Which of the following best describe(s) the function of the 5' mRNA cap?
a) Termination of transcription
b) To provide a binding site for poly(A) polymerase
c) It provides a site for ribosome binding in the cytoplasm
d) To protect the transcript from degradation
Answer:
c) It provides a site for ribosome binding in the cytoplasm
d) To protect the transcript from degradation
Explanation:
Transcription is the very first stage of gene expression, which involves the synthesis of a mRNA molecule from a DNA template. The mRNA transcript produced is referred to as a pre-mRNA until it undergoes further processing in the nucleus. This processing makes it matured and ready to be translated (form protein).
The mRNA processing involves three main processes viz: 5' capping, 3' polyadenylation and splicing. The capping of the 5' of the mRNA involves the addition of a 7-methyl guanosine molecule to the 5' of the mRNA molecule. This capping helps protect the mRNA transcript from being degraded by nucleases (digestive enzymes in the nucleus). In addition to this function, the added CAP also provides a recognition site for ribosome to bind to during translation initiation.
Why does Edwards use the word provoked instead of the word angered in this passage? The word provoked suggests that God’s anger is fierce and irrational. The word provoked suggests that sinners bear responsibility for God’s anger. The word provoked suggests that God’s anger is sharp and deadly. The word provoked suggests that sinners do not want to change their ways.
Answer:
The word provoked suggests that sinners bear responsibility for God’s anger.
Explanation:
From the passage Sinners in the hands of an angry God, Edwards uses the word 'provoked' instead of 'angered' to suggest that God's anger towards the people was as a result of the actions of the people and that they would bear responsibility for it.
The word 'provoked' means to stir up, or provoke someone
The word 'angered' means to be filled with great anger.
Answer:
The word provoked suggests that sinners bear responsibility for God’s anger.
Explanation:
Each orientation of chromosomes produces gametes with the same genetic information from each parent.
a) true
b) false
Answer: a) true
Explanation:
The goal of mitosis is to produce daughter cells that are genetically identical to the mother cell, without a single extra or missing chromosome. Meiosis, on the other hand, is only used for one purpose in the human body: the production of gametes or sex cells, i.e. sperm and eggs. The question is oriented to mitosis, in which prior to this cell division, the cell duplicates its DNA so that each daughter cell then inherits the genetic material. That is, the cell originally possesses 23 chromosomes, they duplicate to a total of 46 so that then each daughter cell receives 23.
The metaphase is the second phase of mitosis and meiosis that occurs after prophase where the envelope is lost and microtubules of the achromatic spindle (also called meiotic or mitotic) appear.
During metaphase, the chromosomes align themselves in the middle of the cell and this balanced midline spindle alignment is due to the equal and opposing forces generated by the kinetochore brothers.
Then during metaphase, the chromosomes will line up in the center of the cell to be separated and go each to a different daughter cell. But the moment they're found there, each orientation of chromosomes produces gametes with the same genetic information from each parent. Because because there have been no changes or mutations in the chromosomes, they have duplicated and have the same genetic information.
A population of finches experiences a drought where all of the normal food types disappear leaving only ant hills that certain finches with thin beaks can access. Over time, almost all of the population has a similar long sharp beak. This is an example of:
Answer:
This question lacks options; the options are:
A) Artificial selection
B) Stabilizing selection
C) Disruptive selection
D) Directional selection
The answer is D) Directional selection
Explanation:
Changes in the environmenal condition affects the distribution of organisms phenotypes. Via this change, organisms with certain traits are naturally selected. The types of natural selection are; stabilizing, disruptive and directional.
Based on the description of the selection in this question, the type of selection is DIRECTIONAL. Directional mutation is that in which one of the two extreme phenotypes in a population is selected against while the other is favored by the occurrence of a natural environmental hazard. The distribution gradually shifts to favour one extreme over the other until the other unselected extreme gets extincted.
This is the case regarding a population of finches affected by drought caused by flood causing all their food source to disappear leaving only ant hills that certain finches with thin beaks can access. This environmental change favorably selects one extreme phenotype (finches with long thin beaks). Hence, a type of DIRECTIONAL selection
What are the two defining characteristics found in organisms that are grouped in the clade Lophotrochozoa
Answer:
A protostome creatures’ clade categorized within the Spiralia is known as Lophotrochozoa. Based on the molecular proof, the taxon was recognized as a monophyletic group. The two illustrating features of lophotrochozoans found in various members are the presence of a small, translucent top-shaped ciliated larvae or trochophores, and the existence of a horseshoe-shaped ciliated tentacles crown known as iophophores.
why blood is classified as tissue in cellular organization?
Answer:
Blood is considered as a connective tissue .
Connective tissues have cells scattered throughout an extracellular matrix. They connect different body systems. Blood is considered as a type of connective tissue because of two reasons.
(i) Like the other connective tissues, blood is mesodermal in origin.
(ii) It connects the body systems, transports oxygen and nutrients to all the parts of the body, and removes the waste products. Blood has an extra-cellular matrix called plasma, with red blood cells, white blood cells, and platelets floating in it.
Answer:
Connective tissues have cells scattered throughout an extracellular matrix. They connect different body systems. Blood is considered as a type of connective tissue because It connects the body systems, transports oxygen and nutrients to all the parts of the body, and removes the waste products

Which type of lipid is shown?
A.) a saturated phospholipid
B.) a saturated triglyceride
C.) an unsaturated phospholipid
D.)an unsaturated triglyceride
Answer:B
Explanation:
Energy receipt is highest between 0° and 23.5° N and S as this is where the sun moves overhead. What would happen if instead the sun moved overhead across a much larger region, such that it was traveling overhead between 0° and 60° N and S? Think about how think might impact certain, major wind patterns.
Answer:
Energy receipt is most noteworthy between the tropics. Had the sun gone up to 60 N and S and back forward, this would have prompted total decimation in significant wind pattern, numerous biomes, for example, Mediterranean biome.
Be that as it may, the most vital effect would have been on the wind patterns since worldwide wind pattern (mainly first order wind) are to a great extent reliant on the weight belt which are constantly influenced by the development of the sun to and fro.
Taking into account that Sun begins its excursion up to 60 N and S, at that point for a day, the Sun would be overhead on this scope. This would imply that during summer solstice (in northern half of the globe), all the weight belts and likewise wind belts would be reached out up to the 60. Thus, the proportionate region under the exchange winds that streams between the equator and the sub-tropical high-pressure belt would increment and the locale under Westerlies effect would additionally build toward the north.
If you have a strand of DNA that reads 3'TACGCGATAGGCAAATT5'. 1. Give the corresponding strand of mRNA 2. Assuming the last condon is a stop codon, will this mRNA strand code correctly for a five amino acid protein
Answer:
1. 5'AUGCGCUAUCCGUUUAA3'
2. No
Explanation:
1. Considering the base-pairing rule, the substitution of the thymine base in DNA with Uracil base in the corresponding mRNA, and the directionality in DNA/RNA; the corresponding mRNA sequence from the DNA strand 3'TACGCGATAGGCAAATT5' would be: 5'AUGCGCUAUCCGUUUAA3'
2. A codon is made up of 3 nucleotide bases. There are 17 nucleotide bases in the mRNA and if the last codon is a stop codon, it means 14 nucleotide bases would be translated. When 14 is divided by 3, there would be 4 complete codons and 2 nucleotide bases would remain. Hence, the mRNA cannot code correctly for a five amino acid protein.
Answer:
5'AUGCGCUAUCCGUUUAA3'
No, the mRNA strand code will not have a five amino acid protein.
1 Explanation:
Use this formula and it can not be the other way around unless stated:
T translates to A
A translates to U
G translates to C
C translates to G
Because the congruent strand is reciprocal to the mRNA strand, the original 3' - 5' would need to be flipped to 5' - 3'
Thus the answer for 1. is 5'AUGCGCUAUCCGUUUAA3'
2. Explanation:
Let's break the sequence into codons.
AUG - CGC - UAU - CCG - UUU - AA
AUG states for the start point so it doesn't count as a five amino acid protein, thus eliminating it.
CGC - UAU - CCG - UUU - AA
As stated in the question, the last codon is the stop codon, thus eliminating that as well.
CGC - UAU - CCG - UUU
Now the remaining codon would be only 4, not five thus it wouldn't have five amino acid proteins.

Can star positions be used to determine the future
Answer:
Since stars basically move freely through space, we can use their proper motions to predict where they will be in the future. A star can also move toward us or away from us, following what is known as radial motion. The combination of radial motion and proper motion determines a star's true motion relative to us.
