Question

This is homework for a practice assessment. I need some assistance with these questions, so I can use them for studying material. Thank you so much! I highly appreciate it!

6. The normal sequence a DNA and the MRNA transcribed from it are shown
below.
DNA- CCCATAATTCTGATTGTATAATGAGTCATTGAATAGTAACAT
DNA- GGGTATTAAGACTAACATATTACTCAGTAACTTATCATTGTA
MRNA-5'-GAUUGUAUAAUGAGUCAUUGAAUAGUAACAU-3'
a) Translate this MRNA, the start codon is underlined.
b) Which strand of DNA is the non-coding strand?
c) Label all ends of the DNA with a 5' or a 3'
d) Circle the +1 on the non-template strand of DNA.
e) On the DNA, draw a box around the promoter region of the gene. f) If the DNA was mutated such that
the "A" immediately after the AUG was deleted what would be the amino acid sequence of the protein
produced from the mutant RNA?

Expert Solution

Step 1

For the expression of a gene, the nucleotide sequences present in the template strand of DNA are transcribed to form a single-strand of mRNA. These mRNA sequences are then, translated to form a long polypeptide chain of amino acids forming protein.
