The combination of mitotic cyclin with CDK signals the __________.
Masteriza [31]

Answer:

The correct answer is beginning of cell mitosis.

Explanation:

Cyclins are cell cycle regulatory protein which regulates the catalytic activity of cyclin dependent protein kinase or CDK.From the name cyclin dependent protein kinase it can be concluded that CDK helps in the phosphorylation of key proteins of cell cycle.

  The combination of cyclin with CDK helps in the progression of cell from one phase to another.

  Such as cyclin A CDK 2 helps also called G1 cyclin CDK helps in progression of cell from G1 to S phase whereas Cyclin B CDK 1 or M cyclin CDK helps in beginning of mitosis phase or M phase of the regulated cell.

aksik [14]

Answer:

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Explanation:

The composition of nitrogenous bases in DNA is calculated using the suggestions proposed by the results of the experiment performed by Erwin Chargaff.

He found that in a DNA sample the composition of purine to pyrimidine is 1:1. This indicates that the amount of purine equals pyrimidine. This can be presented as purines + pyrimidines= 100. Also, adenine binds thymine and cytosine binds guanine.

In the given question,  

<u>For sample A </u>

A= 17.7 %, Therefore, thymine will be = 17.7 %,

A+T= 35.40%

Now, G+C=100- 35.40%

G+C= 64.60%

content of G= 64.60/2= 32.30%

content of C= 32.30%

<u>For sample B </u>

T=28.9%, A will be= 28.9%

A+T= 57.80%

G+C=100-57.80%

G+C= 42.20%

Thus content of G will be= 42.20/2=21.10

content of C= 21.10%

Thus,  

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Most red deer who successfully reproduce have about four fawns during their lifetimes. However, a small percentage of red deer p
Rasek [7]

Answer:

Natural selection will favor red deer that produce a dozen or more offspring that survive for at least a year.

Explanation:

Natural selection results in adaptation, which means the increase of the aptitude phenotype.  Aptitude is the contribution of each genotype to the next generation.

Natural selection is the result between the individual phenotype and the environment that determines the destiny of genes. It is the differential capability of individuals to leave offspring.

Aptitude (or fitness) is the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring. Aptitude must be significant to the natural selection act in its favor.  

Natural selection, eventually, will favor red deer that produce a dozen or more offspring that survive for at least a year. These animals have more chances of leaving fertile descendants that will be able to grow, develop, survive, and reproduce. They have a higher aptitude than those individuals that only have four fawns during their lifetimes. These animals have fewer probabilities of leaving survival descendants able to reproduce.
