Question

Which step begins the process of translation?

Group of answer choices

A ribosome reads the codon sequence at the 5' end of mRNA.

The ribosome releases the protein and detaches from the mRNA.

A stop codon indicates the end of the polypeptide.

tRNA connects an amino acid to the ribosome

Answer 1

Option(a)

A ribosome reads the codon sequence at the 5' end of mRNA.

Explanation:

In the study of molecular biology and genes, translation is a process in which the ribosomes inside cytoplasm synthesize up the proteins after the process of converting DNA to RNA happens in a cell's nucleus. The complete process is known as gene expression

It has three stages such as initiation, elongation and termination. For translation to start sequence of codon should be recognized so the first stage is initiation in which a ribosome reads the codon sequence at the 5' end of mRNA. It follows the stages of elongation and termination.

Answer 2

The correct option is A. A ribosome reads the codon sequence at the 5' end of mRNA.

Step-by-step explanation:

In biology, translation can be described as a process in which proteins are made from the mRNA. The information in an mRNA is in the form of codons. This information is decoded by the ribosomes to form polypeptides. The polypeptides are the building blocks through which proteins are made. The process of translation begins with the step of initiation. In this process, the ribosome reads the mRNA and first tRNA is attached at the start codon.
