Question

Which Characteristics describes the genetic code of humans?

Answer 1

The genetic code refers to the DNA alphabet (A, T, C, G), the RNA alphabet (A, U, C, G), and the polypeptide alphabet (20 amino acids). ... The genetic code is degenerate because 64 triplet codons in mRNA specify only 20 amino acids and three nonsense codons. Most amino acids have several similar codons.

In 1961, Francis Crick and colleagues introduced the idea of the codon. However, it was Marshall Nirenberg and co-workers who deciphered the genetic code.

Answer 2

Explanation:

Genetic code has 4 main features:-

Three nucleotides/bases encode an amino acid, there are 20 different amino acids which are the building blocks for proteins. The genetic code is non-overlapping, for example a sequence UGGAUCGAU is read UGG AUC GAU rather than UGG GGA GAU etc.
