Exam 16: The Molecular Basis of Inheritance

-Refer to the figure above.What bases will be added to the primer as DNA replication proceeds? The bases should appear in the new strand in the order that they will be added starting at the 3' end of the primer.

One major difference in prokaryote replication versus eukaryote replication is

Why do histones bind tightly to DNA?

Suppose you are provided with an actively dividing culture of E.coli bacteria to which radioactive thymine has been added.What would happen if a cell replicates once in the presence of this radioactive base?

How do we describe transformation in bacteria?

Which of the following sets of materials are required by both eukaryotes and prokaryotes for replication?

Which of the following represents the order of increasingly higher levels of organization of chromatin?

How might adding telomerase affect cellular aging?

The elongation of the leading strand during DNA synthesis

The leading and the lagging strands differ in that

A new DNA strand elongates only in the 5' to 3' direction because

You briefly expose bacteria undergoing DNA replication to radioactively labelled nucleotides.When you centrifuge the DNA isolated from the bacteria,the DNA separates into two classes.One class of labelled DNA includes very large molecules (thousands or even millions of nucleotides long),and the other includes short stretches of DNA (several hundred to a few thousand nucleotides in length).These two classes of DNA probably represent

What is the function of DNA polymerase III?

In his work with pneumonia-causing bacteria and mice,Griffith found that

If a mutation occurred in the primase gene,which of the following would you expect?

Which of the following statements is true of histones?

In trying to determine whether DNA or protein is the genetic material,Hershey and Chase made use of which of the following facts?

Which of the following cells have reduced or very little active telomerase activity?

What is the role of DNA ligase in the elongation of the lagging strand during DNA replication?

Until the mid-1940s,which molecule was favoured as the molecule of inheritance?
