<h2>Protein sequence</h2>
Explanation:
- The given sequence is of coding strand(5'-3' direction)
5’-ATGTTGAAAATGCCGTAGAGGC-3’
- Protein is made up of mRNA and mRNA has the same sequence as coding strand(only T is replaced by U) so the sequence of mRNA will be:
5’-AUGUUGAAAAUGCCGUAGAGGC-3’
According to the genetic code,3 bases code for one nucleotide and further nucleotide codes for amino acid,amino acids forms the base for protein
- AUG codes for Methionine(Met)
- UUG codes for Leucine(Leu)
- AAA codes for Lysine(Lys)
- AUG codes for Methionine(Met)
- CCG codes for Proline(Pro)
- UAG codes for stop codon(Stop)
Once the stop codon comes protein synthesis will be stopped,so the final protein sequence will be:
Met-Leu-Lys-Met-Pro-Stop
Answer:
A
Explanation:
The correct answer would be that <u>the availability of food resources for black mice and brown mice will decrease.</u>
<em>Since the food requirements of the black mice are the same as that of the invasive brown mice, the available food supply that used to be only for the black mice would now be shared by the two strains of mice. Hence, the available food for the two groups of mice will naturally decrease.</em>
There is no sufficient information to conclude that the population of tan mice will decrease, hence, option B is incorrect.
The black mice and tan mice have different food requirements going by the information available in the illustration, hence, both cannot compete for food resources. Option C is, therefore, incorrect. In the same vein, option D is incorrect because the tan mice have different food requirements from the brown mice.
<u>The only correct option is A.</u>
