Mutation may or may not affect the phenotype.

Cause: Point Mutation

Effect A: Altered Splice Site

Effect B: Lack of Regulation

Effect C: No Change

Effect D: Non-Coding Regions

Effect E: Premature Stop Codon

What is Mutation?

Mutation is the process of changing the genetic material of an organism. It is the basic process of evolution, and it can occur naturally or be artificially induced. Mutations can be beneficial, neutral, or harmful, and they can affect a single gene, multiple genes, or the entire genome.

A mutation can affect the phenotype, or visible characteristics, of an organism by changing the expression of a gene or by altering the structure of a gene product. Some mutations can have severe effects on an organism’s phenotype, while other mutations may have no noticeable effect. In some cases, a mutation may lead to a change in an organism’s phenotype without changing the underlying genetic code. For example, a mutation in a gene that regulates the expression of other genes may lead to a change in the expression of those other genes, resulting in a change to the phenotype.

state the three laws inheritance by Mendel. explain​

Answers

Mendel's three rules are the Law of Segregation, the Law of Dominance, and the Law of Independent Assortment.

It implies that meiosis is the process of separating two alleles from one another. Two copies of each chromosome are actually separated from one another during the second stage of meiosis, which is when segregation or separation occurs.

The child will inherit the XX genotype and the dominant phenotype if one parent carries the dominant allele X in two copies and the other parent carries the recessive allele X in two copies. The segregation of the allele pair into two daughter cells during the second stage of meiosis division is Mendel's third rule.

The three laws of inheritance proposed by Mendel are: the law of segregation, the law of dominance, and the law of independent assortment.

What are Mendel's law of inheritance?

The three laws of inheritance proposed by Gregor Mendel are:

The law of dominance: This law states that when an organism inherits two different forms of a gene (alleles) for a trait, one allele will be dominant and will be expressed in the organism's phenotype, while the other allele will be recessive and will not be expressed. For example, if an organism inherits one allele for brown eyes (B) and one allele for blue eyes (b), the brown eye allele is dominant and the organism will have brown eyes.

The law of segregation: This law states that during the formation of sex cells (gametes), the alleles for a trait separate from each other so that each gamete receives only one allele. This means that the offspring will inherit one allele from each parent and will therefore have a combination of alleles for a trait.

The law of independent assortment: This law states that the inheritance of one gene or trait is independent of the inheritance of another gene or trait. In other words, the alleles for different traits are inherited independently of each other and are not linked in any way. This means that the probability of inheriting a specific combination of alleles for different traits is the product of the probabilities of inheriting each allele for each trait.

Explanation:

If the Earth did not spin what would happen?
Select one:
a. The Earth's wind would bend due to gravity.
Ob. The Earth would only have two large convection currents.
Oc. The Earth would have the same temperature throughout.
Od. The Earth would have several difference convection currents at different latitudes.

Answers

Answer:

B. The Earth would only have two large convection currents. The power of Earth's spin to turn flowing air is known as the Coriolis Effect. If the Earth didn't spin, there would be just one large convection cell between the equator and the North Pole and one large convection cell between the equator and the South Pole.

Explanation:

At the Equator, the earth's rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.

If the planet stopped suddenly, everything on the surface would be destroyed, as the atmosphere, oceans and anything not nailed down kept spinning. Even braking to a halt over a minute would mean everything experienced a sideways deceleration of three-quarters of Earth’s gravity, so ‘down’ would feel like it was at an angle of 38° from the vertical. That’s enough to knock over most buildings.

If it slowed down over several years, it would still be a disaster. Without centrifugal force, the oceans would move towards the poles, dropping ocean depth by 8 km around the equator. Since this is less than the depth of the ocean there, Earth’s water would be divided into two huge polar oceans separated by a belt of land in the middle. Everything north of Spain would be underwater, as well as all of Antarctica.

Once Earth doesn’t spin on its own axis, a day lasts as long as a year. Everywhere receives six months of daylight, gradually heating up the planet to well over 100 °C. The huge central continent would get the hottest, and any remaining lakes and rivers would boil away and be blown to the poles by fierce winds. Even primitive life would only be possible along a narrow strip at the coast.

Answers

In the sequence of amino acids, a ribosome will read the mRNA about three or more letters at a time, each set is called a codon.

What are amino acids and its sequence?

The sequence of a protein is normally notated as a string of letters, according to the sequence of the amino acids from the amino-terminal to the carboxyl-terminal so to a ribosome, it will gaze like this: AAA-CGA-GGC-UAA. That first codon, AAA, tells the ribosome to start structuring the protein with the amino acid lysine.

Amino acid sequences can be written using either the three-letter code or a one-letter code is the order in which amino acid rest, attached by peptide bonds, lies in the chain of peptides and proteins

What is Peptidoglycans?

In most bacterial species, the cytoplasmic membrane is encased in a hard material called peptididoglycan. It helps maintain cell shape throughout the life cycle and shields bacterial cells from environmental stress. The production of peptididoglycans has a significant role in controlling bacterial cell division. A polymeric macromolecule known as peptididoglycan is composed of linear glycan strands joined together by peptide bridges. The sacculus, which surrounds the cell and is made of covalently closed peptididoglycan, is formed when peptididoglycan is polymerized at the exterior of the cytoplasmic membrane.

Because of its practicality and accuracy, comparative weighing is frequently used to compare two things' masses rather than their absolute values. When preparing reagents and stock solutions, a top pan balance is typically used for rough weighing because minor weight differences do not significantly affect the outcome of analysis.

C.

D.
violet flowers = 0.49, white flowers = 0.61

Answers

The allelic frequency of each type of flower is violet flowers = 0.3, white flowers = 0.7, option C.

What is allelic frequency?

The incidence of a gene variant in a population is represented by the allele frequency. The number of times the allele of interest is observed in a population is divided by the total number of copies of all the alleles at that particular genetic locus in the population to calculate the allele frequency and can be expressed as a decimal, a percentage, or a fraction.

To find the allele frequency:

Frequency = 98/200 = p = 0.49 for white (v) flowers

VV - dominant homozygote with violet flowers and with frequency p²

Vv - heterozygote with violet flowers and with frequency 2pq

vv - recessive homozygote with white flowers and with frequency q²

= 0.49 = √q²  = √0.49 = 0.7

Therefore q in the formula p + q = 1, = p + 0.7 = 1

p = 1 - 0.7 = 0.3

The frequency for violet flowers, p is 0.3 and white flowers, q is 0.7 with substitution method of the "p + q = 1, p2 + 2pq + q2 = 1" formula.
