This is found in the nucleus and codes for proteins
DNA
Molecule/s that transports the codes for proteins
RNA
Copying DNA is called
DNA replication
This is the stage in the cell cycle where DNA is copied
Synthesis
Rule that says base pairs are equal percentage
Chargaff's Rule
DNA has what base pairs?
A, T, G, C
RNA has what base pairs?
A, U, G, C
What is the name of the following Molecule?
DNA
What is the shape of DNA?
Double helix
What is the backbone of DNA made of?
Sugar-phosphate groups
What are the bonds between base pairs called?
Hydrogen bonds
What is this structure?
RNA
List two similarities between DNA and RNA
Both have base pairs C-G,
Both have sugar phosphate back bone
List two differences between DNA and RNA
One is double stranded the other is single stranded
RNA has U while DNA has T
RNA can leave the nucleus
What does semiconservative mean in DNA?
Two copies of the original DNA molecule are produced, each copy replicating the information from 1/2 of the DNA
What is the first step in DNA replication
Unwind the double helix
Which enzyme is responsible for un-zipping the double helix?
Helicase
Which enzyme builds the complementary strands during DNA replication?
DNA Polymerase
When a DNA gene is copied into a strand of mRNA
Transcription
When mRNA is read at the ribosome to assemble amino acids and build a protein
Translation
According to Chargaff's rule, if I have 23% of A bases in RNA, how many of the remaining three bases do I have?
23% A, 23% U, 27% G, 27% C
When does DNA replication occur?
S phase of interphase during the cell cycle
Why is DNA considered semi-conservative?
It is half old/half new
What does anti parallel mean in DNA replication?
The DNA is being made at the same time in different directions.
Who stole Rosaline Franklin's DNA structure discovery and knowingly accepted the Nobel peace prize from a dying woman?
Watson and Crick
