there are 12% cytosines in a DNA molecule , what percentage of thymines

Answers

Answer 1

Answer:

To calculate the percentage of thymine we need to use Chargaff's rule:

Chargaff's rules state that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine

A+G=T+C

A=T

C=G

100%-(2x12)=2T

T=(100%-24%)/2

T=38%

After filling out the information above, answer this question in depth (at least 5 sentences). Use your notes as necessary. Why may chromosomal disorders be more detrimental than DNA mutations?

Answers

Answer: Chromosomal disorders are the disorders that are caused due to the presence of extra chromosomes, or absence of one or more chromosomes or specific part of the chromosomes. Mutation can be defined as the change that occurs in the genetic makeup of the organism either during copy of genome during replication or due to external factors like exposure to ultraviolet radiations, cigarette smoke, and due to carcinogenic agents.

Explanation:

The change in shape of the chromosome as compared to the normal one also exert influence over the functions. Down syndrome, Klinefelter syndrome, Turner syndrome, and others are the examples of the chromosomal disorders. These syndromes affect the normal functioning of the human being rendering it unfertile, rudimentary development of sex organs, development of traits in opposite sex, induce short life span, poor health, lack of proper mental development, and other abnormal characteristics in the effected individuals.  On the other hand mutations are not always detrimental, only a small percentage of mutations can cause genetic disorders. Some mutations can change the genetic makeup by does not affect the functioning of the protein thus the physiological functions of the body are remained restored.

Doctors found out that you are suffering from a serious disease that can only be cured using stem cell therapy. The doctors explain that both adult and embryonic stem cells can be used in your case. Which of the 2 types would you prefer and why? Use facts about each to support your answer.

Answers

Answer:

embryonic stem cells

Explanation:

I prefer embryonic stem cells instead of adult stem cells because embryonic stem cells can be differentiate into any cell type whereas adult stem cells can't be differentiated into other cell type. Due to this feature of embryonic stem cells, it can be used for the therapy and the disease can be cured with the help of these embryonic stem cells. So I prefer embryonic stem cells due to their unique ability of differentiation into any type of cell.

1. A student is completing a Punnett square for a trait (X/x) that is autosomal and inherited by the dominant allele. The father does not have it (xx), but the mother does (Xx). If they had two children, a son and a daughter, what would the completed Punnett square look like (i.e., would the son have the trait, would the daughter have the trait)?

A. Both children would not inherit the trait.

B.Both children would inherit the trait.

C. Each child has a 50% chance of inheriting the trait.

D. One child would inherit the trait and one child would not.

Answers

Answer:

C

Explanation:

autsomsal means that it is not x-linked/ realted to gametes. Dominate means that it needs only one X to get the trait

Using the punnet square

             X       x

      x     Xx   xx

      x     Xx   xx

there is 2 X which means there is a 50% change that their child will get the trait

In the punnett square analysis, each child has a 50% chance of inheriting the trait.

The mother Xx has the trait and the father xx doesn't.

Using the punnet square

Xx                 xx

Xx   Xx  xx  xx

There are just two traits which are Xx and xx which are in equal frequency

and proportion.

This therefore means that the children have a 50% chance of getting the trait.

Answer:

C. when a portion of the moon passes through the earth's umbral shadow.

Explanation:

A partial lunar eclipse occurs when the Earth passes between the sun and moon but the celestial bodies are not arranged in a straight line. When that occurs, a small part of the moon's surface is covered by the darkest, central part of the shadow of the Earth called the umbra. The rest is covered by the outer part of the shadow, termed penumbra.

Answers

Answer:

volcanic islands

Explanation:

As per the diagram given below that shows the model of the plate tectonics and shows the movement of the two plates one plate collides with another and the there moves under due to subduction.

The magma rises and can lead to the formation of volcanic islands. The island is a geologically active part of the plate that rises upwards and is formed by the process of sedimentation.

What is International Astronomical Union?

In 1919, the International Astronomical Union (IAU) was established. Its goal is to encourage and protect astronomy in all of its forms, including research, interaction, education, and development, through international cooperation.

The International Astronomical Union (IAU) is the oldest intergovernmental organization of professional astronomers, having been in existence for over a century. It has over 13000 members and 82 national members, among them India.

The IAU designates a constellation by its boundary rather than its pattern, and the same constellation can have multiple representations. Asterisms should be distinguished from constellations.
