What's the new peptide chain when the new DNA segment is translated?
saveliy_v [14]

Answer:

The correct answer is - Methionine, serine, histidine, aspartate, glycine

Explanation:

The new segment of DNA is: 3'-TACAGGGTGCTACCCACT-5', which performs two processes to form a peptide chain, transcription, and translation. In transcription, the DNA segment is encoded to an mRNA molecule which has its complementary sequence to DNA sequence.

New DNA strand: 3'-TACAGGGTGCTACCCACT-5'

mRNA sequence: 3'-AUGUCCCACGAUGGGUGA-5'

The translation of this mRNA would be on the basis of chart

AUG - Methionine (start codon)

UCC - serine

CAC - histidine

GAU - aspartate

GGG - glycine

UGA -  stop codon

The peptide chain would be - Methionine, serine, histidine, aspartate, glycine

Gulls don’t eat herring but they are apart of the food web. How is the gulls population affected if herring disappeared
pshichka [43]
If the herring was eaten by something that either ate or was being eaten by the gulls, then they would be affected differently. If the gulls had less food because there food source had less food if the herring disappeared, then they would have a lower or population of perhaps become extinct. If the thing eating the herring became extinct because it had less food, then the gulls population would increase and either boom and bust or grow and level out once they reached the carrying capacity.
