Question

(a) Describe the process of amino acylation.
(b) ‘‘Process of transcription and translation are coupled in prokaryotes, but not in eukaryotes.’’ Explain.

Answer 1

Answer:

prokaryotes have nucleus

Explanation:

Answer 2

Steps of amino acylation and protein synthesis

Explanation:

a) Aminoacylation of tRNA means that the amino-acyl-adenylate enzyme complex reacts with tRNA specific for an amino acid to form an aminoacyl-tRNA complex. Enzyme and AMP are released. tRNA complexed with amino acid is called charged tRNA. The charged tRNA is transported to the ribosomes where its anticodon base pairs with codon present on mRNA and transfers its amino acid to the A-site of ribosome.

b) In prokaryotes, protein blend which is called interpretation begins while the mRNA is as yet being combined which is called translation. This is on the grounds that there is no core in prokaryotes that isolates the interpretation and interpretation process. Along these lines, when bacterial qualities are interpreted then transcripts start to decipher right away. Prokaryotic interpretation happens in the cytoplasm close by interpretation and the two procedures happen all the while.
