The function of the ribosome in polypeptide synthesis is to A) hold mRNA and tRN

Question

The function of the ribosome in polypeptide synthesis is to A) hold mRNA and tRNAs together B) catalyze the addition of amino acids from tRNA to the growing polypeptide chain. C) move along the mRNA and eject tRNAs during the translocation process. D) A anti B only E) A, B, and C The following(s) are true about alternative splicing EXCEPT? A) takes place in all eukaryotic mRNA processing. B) takes place in some eukaryotic mRNA processing. C) involved in producing more than one mature mRNAs from one gene. D) happens in the nucleus E) introns are removed from the primary transcript.

Explanation / Answer

39. The answer is 'E'.

Ribosomes are very important in polypeptide synthesis, in this process all 3 types of ribosomal RNAs are involved, they are - rRNA, tRNA and mRNA. The ribosomal RNA moves along mRNA and the amino acids are transcribed by the tRNA.

40. The answer is 'B'.

alternative splicing occurs in all eukaryotes
