Question

1. Which step begins the process of translation?

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


2. What initiates translation?

tRNA brings the first amino acid to the protein chain
a ribosome detaches from the mRNA strand
a ribosome reads a start codon
mRNA leaves the nucleus for the cytoplasm

Answer 1

Answer no 1:

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

Explanation:

Translation can be described as a process in which the information in a mRNA is decoded by the ribosome decoding center of a ribosome. The process of translation occurs after the process of transcription. After transription, the mRNA is moved into the cytoplasm from the nucleus. The ribosomes present in the cytoplasm begin translation by reading the codon sequence present in the mRNA.

Answer no 2:

The correct option is D. mRNA leaves the nucleus for the cytoplasm

Explanation:

Translation is a process in which mRNA is read and proteins are made by reading the codon sequence of the mRNA.

After mRNA is made through the process of transcription, the mRNA made travels to the ribosomes in the cytoplasm. Here,ribosomes read a start codon and tRNA brings anticodons for the codon sequence and the process continues.
