Which nucleotide could be inserted as a mutation in the sequence a—g—a—t—g—c—g—a—g—t—t—a—c—g—g? a. adrenal b. cytosine c. grautine d. thyme

Cytosine could be inserted as a mutation in the sequence. Cytosine is one of the four primary bases found in DNA and RNA, alongside adenine, guanine, and thymine. It is a pyrimidine subsidiary, with a heterocyclic sweet-smelling ring and two substituents joined. The nucleoside of cytosine is cytidine.

The nucleotide that can be inserted as a mutation in the sequence is cytosine. The four nucleotides in DNA are Guanine, Adenine, Cystosine, Thymine. From the choices given the only one that is a nucleotide is cytosine. Since thyme is an herb that can be used for cooking.
