Answer:
The correct option is <em>C. Non-genetic factors can influence expression.</em>
Explanation:
Non- genetic factors can be described as factors other than genetic makeup. These factors include environmental factors and factors arising from the lifestyle of an organism.
Certain studies have shown that both the genetic as well as the non- genetic factors play a role in the development of certain characteristics.
In the above-mentioned scenario, both the monozygotic twins have diabetes but one of them is affected 70% of the time due to his lifestyle. The person might be consuming more sugars and alcohol.
The answer is true. During translation of mRNA, the nucleotides are read by the translation unit (ribosome and trna) in sequences of three (3). These sequences are referred to as codons. Codons code for amino acids. Some codons are start of stop codons meaning they initiate or terminate translation. Additionally, more that one codon could code for one amino acid.
The correct answer is B, I know this because none of the other answers are even reasonable. For example-
A is wrong because the size of elephant tusk has not changed over time, elephant tusk just grow...
C is wrong because it makes no sense to hunt elephants with no tusk :/
D is completely wrong because tusk have nothing to do with reproduction, those are two completely separate bodily functions.........
