Exam 18: The Structural Basis of Cellular Information: DNA, chromosomes, and the Nucleus

The 5' end of a DNA molecule can be chemically distinguished from the 3' end because there is a(n)__________ group at the 5' end and a(n)__________ group at the 3' end.

The data below were obtained as the result of the Sanger method of DNA sequencing.Determine the DNA sequence,making sure to indicate 5' and 3' ends,and add the sequence for the complementary strand.

________ demonstrated that there were equivalent amounts of adenine and thymine and equivalent amounts of guanine and cytosine.

The mitochondrial DNA can be used to identify a species based upon

The specific field of study that examines the gene products of a genome is known as

Which of the following terms is used to indicate the entire set of RNA molecules that can be made by a cell?

DNA isolated from cow liver cells contains 28% A; what percent will be C?

The nucleolus

The nuclear membrane functions as a

You and your neighbor have how much difference in your DNA sequence?

In experiments designed as those of Hershey and Chase (1952),³⁵S was added to a virus replicating within its bacterial host.The new virions were carefully isolated and used to infect fresh bacterial cells in the absence of any radioisotopes.Where would you expect to find the ³⁵S radioisotope?

The scientist credited with the discovery of DNA,which he called "nuclein," from salmon sperm in 1869 is

________ is the name given to DNA characterization based upon digestion of DNA with specific restriction enzymes.

DNA isolated from Aspergillis has an adenine content of 25%.Based upon this information,what is the %G + C within the Aspergillis DNA?

Which one of the following is not characteristic of prokaryotic genomes?

All of the following structures are found within the nucleus of a eukaryotic cell except

DNA is different from RNA in that

The normal gene for hemoglobin was isolated,cloned,and subjected to restriction enzyme digestion with BamHI.Following gel electrophoresis,three bands are routinely obtained.However,following the same procedure with the hemoglobin gene from an individual with sickle-cell anemia,four bands are routinely obtained.These data suggest that
