Below is the 5'-3' strand of a double-stranded DNA molecule with the following nucleotide
sequences:
5' CCTATGCAGTGGCCATATTCCAAAGCATAGC 3'
1.
If the above DNA strand is the coding (sense) strand and the DNA molecule is
transcribed, what is the correct nucleotide sequence and direction of the RNA formed
after transcription?
2. If the RNA synthesized above (item #1) is a functional mRNA and all the nucleotides
belong to an exon,
a. how many codons are present in this mRNA?
b. how many codons actually code for proteins in this mRNA?
c. what stop codon is present in this mRNA?
3.
If the above DNA strand is the template (antisense) strand and the DNA molecule is
transcribed, what is the correct nucleotide sequence and direction of the RNA formed
after transcription?
4.
If the RNA synthesized above (item #3) is a functional mRNA and all the nucleotides
belong to an exon,
a. how many codons are present in this mRNA?
b. how many codons actually code for a protein in this mRNA?
c. what stop codon is present in this mRNA?
