DNA Structure
In DNA, Cytosine always bonds with _____.
What is Guanine?
In the cell, this is where DNA is stored?
What is nucleus?
What is replication fork?
This woman was known for her famous X-ray crystallography photo of DNA?
Who is Rosalind Franklin?
The rungs of the DNA ladder are made of these.
What are bases?
This is the SHAPE DNA is described as.
What is double helix?
The purpose of replication.
What is to produce 2 identical strands of DNA?
DNA replication occurs prior to this.
What is mitosis or cell division?
Scientist(s) who discovered the shape of DNA
Who are Wilkins and Franklin?
Type of base that has 2 carbon/nitrogen rings.
What is a purine?
These two things make up the "backbone" of DNA.
What is phosphate and sugar (deoxyribose)?
The enzyme that adds DNA nucleotides ONLY in the 3' direction.
What is DNA Polymerase?
This enzyme breaks the bonds between the bases.
What is DNA helicase?
Scientist who determined that A=T and G=C
Who is Chargaff?
The idea that percentages of Adenine match up with Thymine and percentages of Cytosine match up with Guanine is called this.
What is Chargaff's rule?
This is the name of the building blocks of DNA (it contains three molecules).
What is nucleotide?
During DNA replication, the complementary DNA strand for ACGTCC would be:
What is TGCAGG?
The type of bonds that have to break in order for replication to occur.
What is hydrogen bonds?
The scientist(s) that physically modeled DNA molecule.
Who is Watson and Crick?
If a DNA strand had 40% cytosine, how much adenine would it have?
What is 10%?
The 3 parts of a nucleotide.
What is phosphate, sugar, nitrogen base.
This enzyme also checks for errors in the genetic code.
What is DNA polymerase?
Because half of the original DNA strand is still present in the new strand, replication is often called this.
What is semi-conservative?
Number of photo that confirmed helix and provided additional measurement info.
What is photo 51?
These bases are considered pyrimidines.
What are cytosine and thymine?
