Lipids and proteins
(however our bodies mostly break down sugars e.g. glucose and are the only molecules we can break down without the need for oxygen)
Both have been impacted by oil drilling and mining.
Answer:
Explanation:PRC1 accumulates on the central spindle in anaphase,
and suppression of PRC1 expression causes failure of microtubule interdigitation.
Answer:
The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.
Explanation:
The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.
In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.
Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.
Answer: B
Explanation:
i think B because it sounds the most right and the other ones jsut don’t make sense
