Answer:
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Answer:
Negative regulation
Explanation:
In the trp operon, tryptophan binds to the repressor protein, then this complex binds to operator effectively blocking gene transcription preventing the production of enzymes that aids in the synthesis of tryptophan. This happens when high levels of tryptophan is detected. This, it is a repressible/negative type of regulation.

Translation is a step in protein biosynthesis wherein the genetic code carried by mRNA is decoded to produce the specific sequence of amino acids in a polypeptide chain. The process follows transcription in which the DNA sequence is copied (or transcribed) into an mRNA.
