Predict what the results would be if mrna were radioactively labeled instead of polypeptides
Vikentia [17]
What  would  happen  if  M RNA   were  radio actively  labeled  instead  of  polypeptides  is   that    instead  of  one  seeing  the  DNA  passing  through  all  the  molecular  factories  you  will  instead see  just  messenger  RNA   taking  code  and   delivering  it  to  Ribosome.  This  is  mainly  found   in   cytoplasm  and  Endoplasmic  recticulums.

In a population of 200, 86 individuals express the recessive phenotype. What percent of the population would you predict would b
Nitella [24]

Answer:

The correct option is;

D. 45%

Explanation:

From the Hardy- Weinberg law, we have;

p² + 2·p·q + q² = 1

p + q = 1

Where:

p = Dom inant allele frequency in the population

q = Recessive allele frequency in the population

p² = The percentage of individuals in the population that are hom ozygous dominant

q² = The percentage of individuals in the population that are homo zygous recessive

2×p×q = The percentage of hete rozyous individuals in the population

The number of individuals that express the recessive phenotype = 86

The number of individuals in the population = 200

The percentage of  individuals that express the recessive phenotype, q² = 86/200 = 0.43

Therefore;

q = √0.43 = 0.656

p + q = 1

p = 1 - q = 1 - 0.656= 0.344

∴ The frequency of  individuals that express the do minant phe notype, p = 0.344

The percentage of heterozyous individuals in the population = 2×p×q × 100 = 2 × 0.656 × 0.344 × 100 = 45.15% ≈ 45%

Natalka [10]
This varieation can be justified because since they had different variations they probably had different niches which led them to evolve differently,this will help because the two species will have no competition
