Question: Enlist the characteristics of genetic code?
The genetic code is the set of rules that determines how the information encoded in DNA or RNA is translated into proteins by living cells. Some of the characteristics of the genetic code are:
- It is universal: The same code is used by almost all organisms on Earth, from bacteria to humans. This suggests a common origin of life.
- It is degenerate: Each amino acid can be coded by more than one codon (a triplet of nucleotides). For example, the amino acid leucine can be coded by six different codons.
- It is non-overlapping: Each codon is read separately and does not share any nucleotides with the adjacent codons. For example, the sequence AUGGCU is read as AUG (methionine) and GCU (alanine), not as UGG (tryptophan) and GCU (alanine).
- It is commaless: There are no gaps or punctuation marks between the codons. The translation process starts from a specific codon (the start codon) and continues until a stop codon is reached, without any interruptions.
- It is unambiguous: Each codon codes for only one amino acid or a stop signal. There are no codons that have more than one meaning or function.
