What is A triplet in DNA replication?
What is A triplet in DNA replication? Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. It was also known that there are only four nucleotides in mRNA: adenine (A), uracil (U), guanine (G), and cytosine (C). What is found in both DNA and messenger RNA? DNA and RNA each contain four different bases (see Figure 4-2). The purines adenine (A) and guanine (G) and the pyrimidine cytosine (C) are present in both DNA and RNA. The pyrimidine thymine (T) present in DNA is replaced by the pyrimidine uracil...
