DNA Structure
In DNA, Cytosine always bonds with _____.
What is Guanine?
This is the site of DNA replication.
What is nucleus?
What is replication fork?
This was used to determine that DNA was a double helix.
What is an X-ray?
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 rebuilds DNA.
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?
Adenine matches up with Thymine and Cytosine matches up with Guanine is called.
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.
The enzyme check 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?
