Homework Answers
1.The answer is a. coding exons are seperated by noncoding introns.
In eukaryote genes, unlike prokaryotes, we can find both coding and non coding sequences in the gene. The coding regions are called exons and noncoding regions are called introns. during posttranscriptional modifications, these introns will be removed form the mRNA.
2. The answer is a. 7.
Explanation is: Two exons are seperated by one intron. simply the formula is "no of exons - 1", so here 8-1 = 7.
3. Rhodopsin is an eukaryotic gene, so it contains both exons
and introns. but if we take mRNA, it contains only exons, coz
during post trascirptional modifications, the introns will be
removed. so, the average number of nucleotides in exon is
=Total number of nucleotides in mRNA/number of exons
= 2768/5 = 553.6 ~ 554.
The answer is a. 554 nucleotides.

QUESTION 31 You have a DNA sequence of 1600 bp. To characterize it, you decide to make a restriction map. Cutting with the first enzyme, you show by electrophoresis that the fragments produced are 400 and 1200 bp, respectively. After using the second enzyme, you recover 700-bp and 900-bp fragments. After treatment with both enzymes, fragments were 300, 400, and 900 bp. Which is the correct map?
