Question

What are the characteristic features of transcripts or mRNA.

Answer 1

• Messenger RNA is single-stranded RNA.
• The mRNA carries genetic information from DNA to ribosome present in the cytosol, where it is used as a template for protein synthesis.
• Messenger RNA is furnished with genetic code (message) as the sequence of codons.
• The message of mRNA is read consecutively in 5' to 3' direction. each amino acid is recognised by specific codon.
• mRNA comprises only about 5% of the total RNA in the cell but is most heterogenous type of RNA in cell varying in the coding region.
