WebThe salient feature of genetic code are as follows: (i) The codon is a triplet. 61 codons code for 20 amino acids and 3 codons do not code for any amino acids, hence they function as stop codons. (ii) One codon codes for only one amino acid, hence, it is unambiguous and specific. (iii) The code is degenerate because some amino acids are coded ... WebMar 27, 2024 · Complete Answer: Genetic code is the sequence of nucleotides in DNA and RNA that determines the amino acid sequence of proteins. i) Commaless: Genetic code is commaless. This means that the arrangement of triplet codons on m-RNA is one after another without a gap. ii) Non-ambiguous nature: Each codon specifies a particular …

WebThe genetic code has following special, features: 1. Triplet Codon: A codon is triplet in nature and is dependent on the sequence of nitrogenous bases in the DNA molecule. A codon codes for a particular amino acid (see Table 6). 2. Commaless: The genetic code is commaless. There are no ‘punctuation marks’ (gaps) between the coding triplets. WebThe genetic code is universal. This means that it is the same in all living organisms. This provides indirect evidence for evolution.

WebA-level Biology – Features of the Genetic Code. Every gene has the following structural features: Start codon: found at the 5’ end of the gene. It marks the beginning of the gene. The start codon has the sequence “ATG”. Exons: regions of the gene which are coding. They contain the codons that are later read to make proteins. WebThe code is degenerate (An amino acid can be specified by more than one codon) 5. The code contains one start and three stop codons. 6. The code is said to be commaless (once reading starts there are no breaks) 7. The code is nonoverlapping. 8. …

WebCells decode mRNAs by reading their nucleotides in groups of three, called codons. Here are some features of codons: Most codons specify an amino acid. Three "stop" codons mark the end of a protein. One "start" codon, …
