DNA is double stranded helix, connected by what could be described as "ladder rungs". These rungs are actually nucleotides, the building blocks of DNA. A sequence of three of these nucleotides is known as a codon. Codons are important in the composition of proteins, because each codon calls for a specific ____________.
A) enzyme
B) helicase
C) amino acid
D) RNA strand

It calls for a specific amino acid.
  • Codons are important in the composition of proteins, because each codon calls for a specific amino acid.
  • Each codon is made up of three nucleotides and each codon present on the complementary mRNA strand made from the DNA is read by the RNA polymerase machinery to and it calls for a specific amino acid attached to a tRNA.
  • The amino acid corresponding to the codons is then incorporated in a growing polypeptide chain to finally make up the protein.
