Question

b. amino acids are required for the proper formation of cell membranes and serve to build connective tissue between cells.
c. amino acids are necessary for the synthesis of nitrogenous bases in dna and rna molecules.
d. amino acids are required during cellular respiration in the formation of atp from glucose molecules.
the image below shows a molecule of dna and a molecule of mrna.
which of the following answer choices correctly identifies the nucleotide sequence of strands x, y, and z?

row	x	y	z

Explanation:

Step1: Match DNA strand Y to X

DNA base pairing: A-T, C-G. For strand X (ACTG), Y is $\text{TGAC}$ (A↔T, C↔G, T↔A, G↔C).

Step2: Match mRNA strand Z to X

RNA base pairing: A-U, T-A, C-G, G-C. For strand X (ACTG), Z is $\text{ACUG}$ (A→U, C→G, T→A, G→C).

Answer:

X: ACTG, Y: TGAC, Z: ACUG
