Which of the following places the steps in the PCR procedure in the correct order?
Marta_Voda [28]

Answer:

Polymerase chain reaction (PCR) test is used to duplicate traces of DNA from any living form, for identification purposes.  The correct sequence is 1, 3, 2; based on the options given.

Explanation:

The steps to be followed for the PCR procedure are:

<em>Denaturation</em>

Option 1.  Involves incubation at 94°C to denature DNA strands into single strands by breaking of weak hydrogen links

<em>Annealing</em>

Option 3.  Temperature is lowered to 60°C to allow primers joining their similar DNA sequences.

<em>Elongation</em>

Option 2.  Incubate at 72°C to promote the extension of the DNA strands, actually extending them.

A survey reveals that 25 percent of a population of 1,000 individuals have attached earlobes (are homozygous recessive for the t
Mumz [18]

Answer:

d. pxp +2pq

Explanation:

The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:

                           p² + 2pq + q² = 1

where, p = dominant allele

           q = recessive allele

Here,

 p² represents frequency of homozygous dominant genotype

2pq represents frequency of heterozygous genotype

q² represents frequency of homozygous recessive genotype

Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.
