Answer:
Explanation:
During prophase I, the homologous chromosomes condense and become visible as the x shape we know, pair up to form a tetrad, and exchange genetic material by crossing over.
The question is:
What may be observed as a result of the described mutation in an individual?
<span>1) Skin cancer due to UV rays </span>
<span>2) Darker blue pigmentation </span>
<span>3) A lack of alterase for other functions it may serve </span>
<span>4) The release of a different pigment color
The correct answer is B.
In this theoretical molecular cascade, we have three key parts, the blue2 gene, the blue2 operator and the enzyme alterase.
The enzyme alterase stops the expression of the blue2 gene by binding to its operator, and therefore the blue pigment protein.
The blue2 operator has a specific binding spot for alterase. If this binding spot is changed due to a conformational change, the alterase would not be able to bind to the operator and the blue2 gene could express undisturbedly, resulting in increased concentration of the blue pigment protein.</span>
Answer:
This occurs at the 3′ end position which sits on an mRNA, while a distinct tRNA anticodon triplet sequence matches a three complementary base pair mRNA codon sequence to guide appropriate amino acid into place at a ribosome activation site to form a polypeptide or protein.

Explanation:
hope it helps, have nice day/night
im sorry didnt do all of them it's a little hard for me
L= liquid
S=solid
G=gas
