Question

What is the function of the process shown which occurs during eukaryotic protein synthesis?

A. A final protein product is being produced at the end of translation.
B. Unnecessary segments of the mRNA transcript are being removed prior to the start of translation.
C. Spliceosomes and snRNPs are excising exons and producing a final RNA transcript.
D. A mutation is being repaired by enzymes before translation begins.

Answer 1

Hint: Protein Synthesis can be defined as the process in which the molecules of amino acids are arranged as a single line into proteins by involving ribosomal RNA, transfer RNA, messenger RNA, and other enzymes. The complete process of transcript and change is called DNA segment.

Complete answer:
> Translational unit of mRNA from 5’ to 3’ includes start codon, region coded polypeptide, a stop codon, and untranslated regions (UTRs) at 5’ end & 3’ end both for more efficiency of the process.

> The ribosome is the place where the whole machinery of translation is present. Each eukaryotic ribosome has two parts smaller 405 subunit and a larger 60S subunit. The lowest unit has a fact for addition of mRNA

> Splicing is the removal of introns from the primary transcript and litigation of exons to form a continuous sequence specifying a functional polypeptide and is mediated by a set of snRNPs together forming spliceosomes. A spliceosome is a great compound molecular apparatus created within the merging specks of the core of eukaryotic cells.

> The bent in the chain of each tRNA molecule contains a definite sequence of three nitrogenous bases that constitute the anticodon. It recognizes the codon on mRNA

Hence, the correct answer is option (C).

Note: Proteins are organic compounds that are made of one or more than one chain of amino acids, or the polymers of amino acids. The amino acids in proteins are linked with each other by a peptide bond. Protein synthesis is completed by the process of protein translation. When the DNA fragment has recorded a transcript, the messenger RNA is turned for protein synthesis.
