Why is a mutated single copy of a tumor-suppressor gene expected to behave as a recessive gene?

Biology

Doss [256]3 years ago

This is mainly because in order to the tumour suppressor gene to be completely expressed or to no longer be effective in repressing cellular production, both versions, alleles of the gene must be mutated. This is the only way that the rumour suppressor gene to be inactive in its role and behave as a dominant gene.

A particular triplet of bases in the template strand of DNA is 5' AGT 3'. The corresponding codon for the mRNA transcribed is __
earnstyle [38]

Answer:

The correct answer is 3' UCA 5'

Explanation:

The rule of pairing of base-pair says that A and T base pairs with each other with two hydrogen bonds and G and C base pairs with each other with three hydrogen bonds in DNA. In the case of RNA Uracil comes at the place of thymine that means uracil replaces thymine.

Therefore according to this base-pairing rule the corresponding codon of mRNA transcribes from DNA codon 5' AGT 3' will be 3' UCA 5' as U came in place of A nucleotide, C comes in place of G nucleotide, and A comes in place of T nucleotide.  

Therefore the correct answer is 3' UCA 5'.
