b. The entire base sequence of an mRNA molecule
c. The entire sequence from the promoter to the terminator of a gene
d. The binding of tRNA to mRNA
The sequence of bases in a sample of
MRNA was found to be:
GGU,AAU,CCU,UUU,GUU,ACU,CAU,UGU
a Deduce the sequence of amino acids this
codes for.
b Determine the sequence of bases in the
coding strand of DNA from which this
MRNA was transcribed.
c Within a cell, state where the triplet codes,
codons and anticodons are found.
Why might a single base-pair mutation in eukaryotic mRNA be less serious than one in prokaryotic mRNA?
a. If the mutation occurs in the 5' end of the start site, it will not affect the gene product.
b. If the mutation occurs in the exon, it will not affect the gene product.
c. If the mutation occurs in the splice site of a transcript with alternative splicing, only one gene product may
affected.
O d. If the mutation occurs in the intron or not in the splice site of a transcript with alternative splicing, it will nc
affect the gene product.
O e. If the mutation occurs in the 3' end of the start site, it will not affect the gene product.

Why is this so? A. RNA splicing occurs and removes the noncoding sequences. B. The poly-A tail and 5' GTP cap do not translate into proteins. C. The adenines are reabsorbed by the cell and help to form other forms of RNA. D. The tRNA does not recognize the poly-A tail.arrow_forward
