Best Answer

In DNA, there are 4 different kinds of nucleotides. A, T, C and G

In RNA, there are also 4, but T has been replaced by U. (I think. It's been awhile)

So there are 81 combos that you might see in real life, but there are 243 that you could prepare in a lab.

three.


How many codons are there in an mRNA with 75 nucleotides?

There are 25 codons in an mRNA with 75 nucleotides because each codon consists of a sequence of three nucleotides.


How many nucleotides are needed to 'read' or place a single amino acid?

Three.


How many nucleotides are required to encode one amino acid?

Three nucleotides are required to encode one amino acid in the genetic code. This unit of three nucleotides is called a codon and it corresponds to a specific amino acid.


How many tRNA nucleotides form an anitcodon that will attach to the mRNA codon?

The codon and the anticodon interact with each other via hydrogen bonding, hence both the codon and anticodon are made up of the same number of nucleotides, which is three.


How many DNA nucleotides make up a gene with a protein with 150 amino acids?

A gene with a protein containing 150 amino acids would require 450 nucleotides. This is because each amino acid is coded by three nucleotides in DNA.


How many nucleotides are necessary to code for a polypeptide that is 200 amino acids long?

A minimum of 600 nucleotides is necessary to code for a polypeptide that is 200 amino acids long because each amino acid is coded for by a sequence of three nucleotides in mRNA. This is due to the genetic code being triplet, where every three nucleotides represent one amino acid.
