Question

36. The genetic code is said to be degenerate. This means that (2 points) each codon codes for more than one amino acid each tRNA anticodon can interact with several codons, that may differ in any or all of bases the aminoacyl tRNA synthetase enzyme can recognize several different amino acids several amino acids are coded by several codons that can differ only in the third base c c) the genetic code is universally used by virtually all species 37. Which of the following sequences ensures the correct alignment between the ribosome and mRNA (2 points) a) -10 region b) 35 region c) Fis regulatory sequence d) Shine Delgarno sequence e) UP element

Explanation / Answer

Q36:- Option B

Explanation:- Each tRNA anticodon interacts with several codons that differ in any or all of the bases. This is also called redundancy of genetic code and was explained in terms of wobble hypothesis by crick 1958. Since there are 64 codons out which 61 code for amino acids. But there are less than 45 tRNAs this means some tRNAs recognise more than one cofons.

Q37:- Option D

Explanation:-Shine Dalgarno sequence also called RBS ribosome binding site (AAGGAGG) a hexameric polyputine rich sequence that is complementary with 16s RNA OF ribosome that has anti shine dalgarno sequence UCCUCC that facilitates binding mRNA with ribosome.
