Answer: A. Phosphodiester bond.

Explanation: "A phosphodiester bond occurs when exactly two of the hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. <u>Phosphodiester bonds are central to all life on Earth as they make up the backbone of the strands of nucleic acid."</u>

"The nucleotides in DNA and RNA have three components: a sugar group, a nitrogenous base, and a phosphate group.<u> Adjacent nucleotides in a nucleic acid are joined by a phosphodiester bond." </u>

Calculate the mass in amu of a sample of carbon that contains 62 atoms
victus00 [196]

744 atomic mass units (a.m.u)

Explanation:

We know that 1 carbon atoms weighs 12 atomic mass units (a.m.u). Knowing this we devise the following reasoning:

if        1 carbon atom have a mass of 12 atomic mass units (a.m.u)

then  62 carbon atoms have a mass of X atomic mass units (a.m.u)

X = (62 × 12) / 1 = 744 atomic mass units (a.m.u)
