Answer:
Characteristics of the Genetic Code
The genetic code is universal. All known living organisms use the same genetic code. ...
The genetic code is unambiguous. Each codon codes for just one amino acid (or start or stop). ...
The genetic code is redundant. Most amino acids are encoded by more than one codon.
Promoter: In molecular biology, a site on DNA to which the enzyme RNA polymerase can bind to initiate the transcription of DNA into RNA.
t RNA;- Transfer RNAs or tRNAs are molecules that act as temporary carriers of amino acids, bringing the appropriate amino acids to the ribosome based on the messenger RNA (mRNA) nucleotide sequence. In this way, they act as the intermediaries between nucleotide and amino acid sequences.
Exons;- a segment of a DNA or RNA molecule containing information coding for a protein or peptide sequence.
