Question

Explain the role of each of the following in protein synthesis in eukaryotic cells. • RNA polymerase • Spliceosomes (snRNPs) • Codons • Ribosomes • tRNA

Answer 1

Answer:

The Central dogma includes the replication, transcription and translation.

Explanation:

RNA polymerase; It is invloved in transcription process in which the the squence of DNA is coppied to RNA known as mRNA.

Spliceosomes; The genetic information is in non-continuous form i.e introns (non-codding sequences) are present between exons. These introns are removed by spliceosomes from pre-mRNA.

Codons; Codon is the sequence of three nucleotides on mRNA that code for specific amino acid i.e AUG for methionine.

Ribosomes; These are known as protein factory because protein synthesis take place in ribosomes.

tRNA; It brought the specific amino acids for corressponding codon on mRNA for polypeptide chain.
