levacccp [35]

Answer:

a. 0.7

b. 0.3

c. Yes

d. 90

Explanation:

As the random mating population was escaped from external evolutionary forces such as mutation, natural selection, and migration, the gene frequency will not change over time. The population will be at Hardy-Weinberg equilibrium throughout the time.

<u>As the number of sleepyheads (recessive trait) was 90 out of class of 1000 students at the start of course.</u>

<u />

q²=0.09 ∵ fraction of sleepyheads = 90/1000 = 0.09 denoted by q²

q that is the recessive gene frequency will be equal to 0.3 (by taking square root of P²

Hence, <em>allele frequency of a allele is 0.3</em>

<em></em>

As, frequency of dominant allele A is denoted by letter p and p+q=1

∴ p=0.7 As p=1-0.3

Hence,<em> allele frequency of A allele is 0.7</em>

<em></em>

Counting the probability of aa alleles (sleepyheads);

As a= 0.3

∴ aa= 0.3×0.3 = 0.09 (In terms of percentage, it is 9%)

To 0.09×1000= 90 or 9% of 1000 = 90

Hence, 90 students should be sleepyheads.

Why are ribonucleoside triphosphates the monomers required for rna synthesis rather than ribonucleoside monophosphates?
torisob [31]

Answer:

The phosphates provide energy for the bond between each nucleotide.

Explanation:

When each nucleotide is being bound, the two extra phosphates provide the energy needed for it to form the bind between each nucleotide that's being added to the RNA. Without this energy, the RNA wouldn't be able to form due to the lack of enough energy.
