It has four.
There are 9 * 8 * 7, or 504, three letter permutations that can be made from the letters in the work CLIPBOARD.

Six.
There are 13 combinations.
Three nucleotides makes up each codon. The codons consist of combination of 4 differing nucleotides A,G,T, and C.
Nine nucleotides are needed to specify three amino acids.
A three-nucleotide sequence makes up a codon.

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