Answer:

C. Nucleotides

Explanation:

Nucleic acids are macromolecules which are polymers of nucleotides. There are two types of nucleic acids namely: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleotides are the building blocks of nucleic acids.

A nucleotide is made up of three components:

- A phosphate group

- A five carbon sugar called pentose sugar. In RNA the sugar is ribose sugar and in DNA the sugar is deoxyribose sugar.

- Nitrogenous bases: There are four different types of bases in DNA: adenine, guanine, cytosine and thymine. In RNA thymine is replaced by uracil. Adenine and guanine are purines whereas cytosine, thymine and uracil are pyrimidines.

Nitrogenous base and sugar together are called nucleoside and when phosphate is also attached then it is called nucleotide.

The genetic code is redundant. What is meant by this statement?
storchak [24]

Answer:

This means that one amino acid can be coded by more that one codon.

Explanation:

A triplet code that code for an amino acid during translation is called genetic code. The genetic code is said to be redundant because a single amino acid can be coded by more that one triplet codon.  

So there can be synonymous codon for one amino acid. For example, leucine, serine, and arginine have 6 synonymous codons.

The genetic code is unambiguous also because each triplet codon can only code for a particular single amino acid. Genetic code is also universal which means the same code is used in all life forms.
