Homework Answers
The goal of in vitro transcription is to synthesise a RNA product from any stretch of gene (s), outside the body, in culture conditions which can be precisely regulated.
We synthesise the RNA to study the molecular mechanisms of transcription and the ways by which it can be effected by an external stimuli.
It can be used for the synthesis of microRNAs and anti-microRNAs; Riboprobe synthesis for Northern blotting and in situ hybridization; RNA aptamer synthesis for SELEX; CRISPR gRNA synthesis for RNP-mediated gene editing etc.
tRNA act as an adapter molecule, owing to its 3 leafed clover structure, it helps in decoding the information in mRNA to protein product by interacting with both of them simultaneously. The tRNA binds to its specific amino acid attached to its end and subsequently upon binds to its corresponding codon in the ribosome, it transfers this amino acid to the end of the growing amino acid chain. It is used to enhance the translational efficiency by lifting translational rate.
