Question
The type of RNA that carries information for the sequence of amino acids during protein synthesis is ______________.
Open in App
Solution
The information from one of the strands of DNA is copied to mRNA by a process known as transcription. The sequence of nitrogenous bases in the mRNA thus formed define the order and sequence of amino acids in a polypeptide chain .
During protein synthesis, these bases are read by the ribosome in triplets. Each triplet codes for an amino acid and are called codons.
rRNA or ribosomal RNA is a major constituent of ribosomes. It is involved in catalysing the peptide bond formation between amino acids.
tRNA brings amino acids from the cytoplasm to the ribosome to form the polypeptide chains.
In eukaryotes, transcription results in the formation of hnRNA (heterogenous nuclear RNA). It consists of coding and non coding sequences. hnRNA undergoes further processing like splicing, capping and tailing to form functional mRNA.
