Question

How does the presence of tRNA in ribosomes allow ribosomes to manufacture proteins?

It allows for random distribution of amino acids.

It stores information about proteins already manufactured.

It allows sequencing of amino acids based on an mRNA template.

It stores chemical energy required for manufacturing proteins.

Answer 1

It allows sequencing of amino acids based on an mRNA template.

Step-by-step explanation:

I took the quiz and got this correct.

Answer 2

The presence of tRNA in ribosomes allows the sequencing of amino acids based on an mRNA template. This is the process of translation which takes place in the ribosomes, that are made of RNA and protein. Ribosomes organize translation and catalyze the reaction that joins amino acids to make protein chain. The tRNA work is therefore to read the message on the mRNA and then translate it to amino acids, such that each individual codon corresponds to an amino acid.
