A codon is a string of bases in RNA that code for a specific amino acid. How many nucleotides make up each codon?

Each codon on the RNA is made up of three nucleotides.

Explanation:

A codon is a triplet of nucleotide which codes for a specific amino acid. A codon is made up of three nucleotides residues. There are 64 codons in existence. Every amino acid is coded for by at least one codon. An amino acid can be coded for by one or more codons. One out of the 64 codons (AUG) is the initiation or start codon which signals the commencement of translation, the initiation codon AUG also codes for methionine. Three out of the 64 codons do not code for any known amino acid and hence are called nonsense codons or stop or termination codons. They signal the termination of translation. The three termination codons are UGA, UAA and UAG.

Hope I helped and Have a wonderful day

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
