DNA Structure
In DNA, Cytosine always bonds with _____.
What is Guanine?
Where is the DNA located when it replicates (or is copied)?
What is nucleus?
tRNA
This technology or instrument was used to "see" and 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?
The type of RNA that "copies" the complementary strand from the DNA?
mRNA
Scientist(s) who discovered the shape of DNA using X-Ray Chromatography?
Who is Rosalind Franklin?
Type of base that has 2 carbon/nitrogen rings.
What is a purine?
These two things make up the "backbone" (or sides) of DNA.
What is phosphate and sugar (deoxyribose)?
The enzyme that "cuts" open the 2 DNA strands?
What is DNA LIGASE?
What is the ribosome or cytoplasm?
Which scientist determined that the % of Adenine always =the % of Thymine. Same applies to 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 RNA that "clamps on" and translates the message from the mRNA.
What is rRNA?
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 that rebuilds or "glues" DNA back together after replication occurs.
What is DNA Polymerase?
The type of RNA that is called the CODON and is used to read the amino acid chart.
If a DNA strand has 20% Adenine, what % is Cytosine? (Think?)
30%
The type of bond that attaches amino acids.
What is peptide?
