Answer:

Phosphate group

Explanation:

Each nucleotide consists of a heterocyclic base linked via a five-carbon sugar (deoxyribose or ribose) to a phosphate group. DNA and RNA each contain four different bases. The purines adenine (A) and guanine (G) and the pyrimidine cytosine (C) are present in both DNA and RNA. So both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine). One of the most significant similarities between DNA and RNA is that they both have a phosphate backbone to which the bases attach.

Which of the following is not attached to the central carbon atom in an amino acidA. A carboxyl functional groupB. An amino func

gavmur [86]

Answer:

The correct answer is C. An oxygen

Explanation:

Amino acid is a compound which serves as the building block or proteins. They are the smallest and simplest unit of protein. They contain carbon, oxygen, hydrogen, and oxygen.

Each amino acid has a central carbon atom which is designated as alpha carbon which is attached with a carbonyl functional group, an amino-functional group, a hydrogen atom, and a side chain(R group). So oxygen is not bound directly with the central carbon atom.

The R group is different in different amino acid. Glycine is the simplest amino acid and it has H in place of the R group.
