Crossing over is important because it creates genetic variability.
<h3>What is crossing over?</h3>
It is the exchange of chromosomal segments between non-homologous chromosomes in a tetrad.
Since chromosomal segments contain genes at different loci, the exchange will increase the genetic variability of the new chromosomes.
Thus, the daughter cells carrying the recombined chromosomes will be genetically variable from not just the parent cell, but fellow daughter cells.

Answer:
d) Increasing the pH makes it easier for lactase to function correctly.
Explanation:
The answer is Ser-Arg-Ala-Val-Gly-STOP
It is known that three nucleotide bases on mRNA are called
codon and that each codon codes for the specific amino acid. According to the
genetic code chart, the following mRNA sequence will code for the following
amino acid sequence:
mRNA sequence: <span>UCU CGA GCC GUU GGG UGA</span>
Amino acid sequence: Ser Arg Ala Val Gly STOP
