Watson and Crick used this term to describe the shape of DNA.
What is a double helix?
100
Multiple origins of replication
How does DNA replicate in a reasonable amount of time?
100
RNA polymerase
What enzyme is responsible for creating mRNA?
100
In the ribosomes in the cytoplasm of the cell
Where does translation take place?
100
The addition of nucleotides in a DNA sequence.
What is an insertion mutation?
200
The sugars and the phosphates.
What is the "backbone of a DNA molecule"?
200
Helicase
What is the protein responsible for unwinding of DNA?
200
Inside the nucleus
Where does transcription happen?
200
Codons
As the ribosome is running down mRNA, it reads these.
200
DNA, mRNA, tRNA, proteins
Where can mutations occur?
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 complimentary base pair?
300
messenger RNA
What is the end product of transcription?
300
A 3-nucleotide sequence used to recognize for an amino acid
What is a codon?
300
When a single nucleotide mutation occurs.
What is a single polymorphism (SNP)?
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 III?
400
Outside the nucleus into the cytoplasm
Where does RNA go after transcription is over?
400
An anticodon
tRNA is recognized and attached to the mRNA by this.
400
This is one of the worst mutations. It is usually accompanied by an addition mutation, and can result in a "misread" of all other amino acids downstream of the site of mutation.
What is a frameshift mutation?
500
With a DNA double helix, the strands run in opposite directions.
What does anti-parallel structure mean with DNA?
500
The proteins which the DNA double helix winds around so that DNA can become "supercoiled".
What are histones?
500
Ribosomes in the cytoplasm
Where will mRNA go to start translation?
500
A protein
The collection of amino acids after translation hits the STOP codon UGA.
The end product
