Answer:
C
Explanation:
Add radio labeled actin sub units to a mixture of actin filaments in which conditions are favorable for polymerization. This would enable you to identify the plus end of actin filaments.
Actin filaments are linear polymer of globular actin sub units Actin filaments have polarity. This means that the two ends can be identified due to structural differences.
Answer:
Option (d).
Explanation:
Enzymes are bio catalyst that can increase the rate of a bio chemical reactions of the body. Enzymes work at specific pH and temperature conditions only.
The activity of enzyme is highest at its optimum temperatures. The treatment of enzyme with excess heat or cold can decrease the enzyme activity. The exposure to cold decreases the activity of a enzyme as motion of the molecules decreases at low temperatures.
Thus, the correct answer is option (d)
The answer <span>is AB and aB
<span>A man is heterozygous for sickle cell anemia: Aa
</span></span>A man is <span>homozygous dominant for familial hypercholesterolemia: BB
So, his genotype is AaBB. He will give only one allele of two for each gene.
He can have 2 different combinations in sperm cells:
- AB
- aB</span>
