What do proteins and nucleic acids have in common? a. they are both polymers that are found in living cells. b. they are both components of dna. c. they are both polymers made from amino acid monomers.

A.They are both polymers that are found in living cells.

Explanation:

The monomers are small units or molecules which join with each other end in a huge to end and give rise to the polymers.

If we talk about proteins and DNA, both are the polymers because they are made up when hundreds and thousands of small monomeric units combine.

In case of DNA, those monomeric units are Nucleotides but in case of proteins, these monomeric units are amino acids.

Nucleotides in case of DNA are basically a set of three components, a pentose (five-carbon) sugar that is called de-oxyribose, a nitrogenous base (Adenine or thymine or guanine or cytosine) and a phosphate group (PO4). These nucleotides join with each other through phospho diester linkage when 3'-OH group of one nucleotide is linked to 5' phosphate group  of the other nucleotide. The number of nucleotides can vary from thousands to millions that join and give rise to a molecule of DNA.

Now, if we talk about proteins, their monomers are amino acids. There are 20 different types of amino acids and a specific protein can either be made up of amino acids of one type or other types. These amino acids are joined by peptide bonds to give rise to long chains of units, which ultimately go through some structural transformation to build a proper protein.

Hope it helps!

i'm wiling to try and you : )
