DNA Structure
DNA Replication
Where does it happen?
Misc.
100
Watson and Crick used this term to describe the shape of DNA.
What is a double helix?
100

This is what results from copying one strand of a DNA double helix

What are two strands of DNA?

100
This is where DNA replication takes place.
What is the nucleus?
100

New nucleotides are added on to this carbon of a nucleotide

What is the 3' Carbon?

200
The sugars and the phosphates.
What is the "backbone of a DNA molecule"?
200
This is the first step in the replication of one DNA molecule.
What is the unwinding of DNA?
200

A single ring

What are pyrimidines? (also C/T/U)

200

The fragment of DNA added to the lagging strand during replication

What is the Okazaki fragment?

300
The type of bond that holds bases together in the double helix.
What is a hydrogen bond?
300
This is what you call a "G" binding with a "C" or an "A" binding with a "T".
What is a base pair?
300

Adenine and Guanine

What are purines?

300
With RNA, A (adenine) binds with this other base.
What is U (uracil)?
400
A (nitrogenous) base, a sugar, and a phosphate.
What are the 3 parts of a nucleotide?
400
The enzyme that is used to make a copy of a DNA molecule.
What is DNA polymerase?
400

This is what holds the mRNA strand in place while translation proceeds. (proteins are made with this organelle)

What is the ribosome?

400

Enzyme that links two sections of DNA together after DNA polymerase is done

What is ligase?

500
He is credited with the discovery that the amount of G's was roughly equal to the amount of C's (and A's with T's) in several samples of DNA.
Who is Erwin Chargaff?
500
The proteins which the DNA double helix winds around so that DNA can become "supercoiled".
What are histones?
500
When mRNA is transcribed from DNA, it then slips through these to get into the cytoplasm.
What are the nuclear pores?
500
DNA is an abbreviation for this term.
