Question
If an mRNA sequence in the 5'-3' direction usually begins UGG AUG UCG CCC AUA, what would you expect to happen if the guanine in the third position is deleted from the mRNA sequence? AGUCAG Stop Valine A Cysteine A Stop G Tryptophan ArginineG A Leucine Serine U A Adenine U Uracil G Guanine C Cytosine Click to view larger image. The incorrect amino acid will be added in the first position The correct amino acid will be added in the first position Tryptophan will be the first amino acid added to the chain The mRNA will not be translated into a protein at all.Explanation / Answer
In mRNA ribosome will find methinine as first amino acid. Once AUG will find they start protein synthesis. Here UGG is just before the AUG hence deletion will not make any change in this translation. Second answer is correct that is correct amino acid will be added in the first position.
Population geentics is a branch of genetics that gather information about genetic difference between populations. Whereas transimission genetics restrict to a particular family or lineage and study the gene transmission, Here 3rd option is correct.
