Chapter 17, Problem 21RQ
Summary Introduction
To review:
The total number of base pairs and the length of the deoxyribose
Introduction:
The DNA is the inherited material of the cells. It is a double-stranded polynucleotide comprising deoxyribose sugar and nitrogenous basesthat are adenine (A), thymine (T), guanine (G), and cytosine (C). In a cell, DNA is compacted in the form of chromosomes. It is found as finethreads thatcoil around themselves to form a helical structure.

- Question 1. Although we will not be doing a gel electrophoresis, data from a gel digest of a Bacillus anthrax plasmid is provided so you can do a DNA map. The Bacillus anthrax plasmid is 4000bp (4Kb) long. Note the origin position as well as the reference molecular weight markers on the gel. Two restriction enzymes, A and B, were used to obtain two individual digests, A and B. They were combined to produce the third digest.

Since the top and bottom strands of this restriction site are identical in the 5'-3' direction, only one strand of the site needs to be shown. The single-stranded ends produced by Sau3A cleavage are identical to those produced by BamHI, which recognizes the sequence 5'-G/GATCC-3' and cuts at the location of the slash. This means that an end cut by one enzyme can be ligated onto an end cut by the other enzyme by DNA Ligase. Given this information, answer the following questions: A) Write out both strands of the recognition sequences for BamHI and Sau3A, show what they would look like after they are cut, and what the DNA would look like after you ligate a BamHI site to a Sau3A site. Make sure that it is easy to follow the individual pieces of DNA. You may want to use two different colors to keep them separate. B) What fraction of BamHI sites can be…arrow_forward
- Question 1. Suppose that the diagram below represents the genomic organization of an enzyme involved in eye pigment production in mice. Within the gene are four exons. Biochemical analysis has revealed that the active site of the enzyme is located in the C terminus of the protein. The nucleotide length of each exon and intron is shown. The dinucleotide sequence GT represents the 5’ splice site and the dinucleotide sequence AG represents the 3’ splice site. Both the 5’ and the 3’ splice sites must be present for splicing to occur. Assume that the first and second stop codons are located immediately after the first and second 5’ splice sites, respectively; the third and fourth stop codons are located near the 3’ end of exons 3 and 4, respectively; all these stop codons are in the correct reading frame. E) Suppose you isolate a mutant mouse that has white eyes. When you examine the size of the eye pigment enzyme produced by this mouse, you see that it is 400 amino acids long.
