Answer:
In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).
Explanation:
Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.
From the sequence:
AUGGUGCAUGUC
Four codons are obtained, each of which encodes a different amino acid:
<em>Codons: AUG-GUG-CAU-GUC</em>
<em>Amino acids: Met - Val - His - Val</em>
<em>Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.</em>
Answer:
A. It allows two populations to evolve separately.
Explanation:
Geographic isolation is theorized to have catalyzed the formation of new species. Let’s say groups A and B of a bird species get separated by something, and they can’t cross between to interbreed or exchange alleles.
We describe this as no gene flow, which is the opposite of choices C and D. Because of this, they may diverge if given enough time due to the difference in environmental pressures, because they’re now in different environments.
B is incorrect because it doesn’t apply.
85% of adults are grandparents by age 65. This estimation has been made in the U.S. from the surveying of the elderly. So, the correct choice is the third option: 85.
