If a mutation occurred that increased the number of exons in a sequence of DNA, what impact would this have on the protein forme
erastovalidia [21]

Answer:

See the answer below

Explanation:

<em>An increase in the number of exons in a sequence of DNA would result in another protein with a longer amino acid sequence.</em>

<u>Exons are the coding part of a gene as opposed to introns. After transcription, the non-coding part of the gene - the introns - are removed by splicing and the exons are joined back together. The final RNA that will undergo translation consists of only exons. </u>

The longer the exons in a gene, the more the codons present in the corresponding mRNA from the gene, and the more the number of amino acids that would be translated from the mRNA. A longer amino acid chain would result in a different protein.

Hence, a mutation that causes an increase in the number of exons in a sequence of DNA would result in a different protein with a longer amino acid sequence.

Select the statements that best explain Makali's GALT activity levels? Makali may have a mutation in the gene that encodes galac
adelina 88 [10]

Answer:

Makali may produce only small amounts of a non-mutated (wild-type) GALT enzyme.

Makali may have normal amounts of GALT, but the enzyme may be mutated.

Explanation:

Makali is lactose intolerant because of his ancestry. Because of this he is not able to digest any lactose which indirectly protected him from galactosemia. Thus he must avoid consuming galactose. He has a low GALT or galactose 1‑phosphate uridylyltransferase activity. He has a normal amount of GALT and may produce only small amounts.
