The correct answer for this question is "Epiglottis". The Epiglottis is responsible for cutting off the passage way to the airway while swallowing/eating food to prevent the food from being inhaled by the body.The Epiglottis has a leaf-like shape structure with a cartilage that covers the passage way into the air ways of the body.
The possible tRNA for serine are UCU, UCC, UCA, UCG
Answer:
On the basis of the phenomenon of the degeneracy of codons, the coding of single amino acid can take place by various codons like four different codons, that is, CCC, CCU, CCG and CCA can code for single amino acid proline.
In case, if there is a mutation in DNA, due to which CCA get transformed to CCG, even in such case coding for the same amino acid proline will take place. Hence, one can conclude that at the level of DNA mutation is taking place, however, the same is not getting witnessed in a protein, and that is why such kind of mutations are termed as silent mutation.
Answer:
<h2>40</h2>
Explanation:
Calculations:
Let q²= homozygous recessive
p²= homozygous dominant
2 pq heterozygous
q² for this population is 640/1000 = 0.64
q = √o.64 = 0.8
so, P= 1- q
= 1- 0.8 = 0.2
The homozygous dominant frequency = p² = (0.2)(0.2) = 0.04
Therefore, you can expect 4% of 1000, or 40 individuals, to be homozygous dominant.
