DNA Replication
Transcription
Translation
Operons
100
A single ringed nucleotide, such as T or C.
What is a pyrimidine?
100
Knowing exactly what nucleotide will complement another.
What is specific pairing?
100
The start codon.
What is AUG?
100
The RNA that translates the transcriptional RNA.
What is tRNA?
100
A series of genes that codes for lactase production.
What is the lac operon?
200
The number of rings that make up the width of any given point of double stranded DNA.
What are 3 rings?
200
The enzyme that connects the fragments made on the lagging strand.
What DNA ligase?
200
When multiple codons code for an amino acid.
What is redundancy?
200
Where the transcription RNA goes after the first site, containing the entire chain of amino acids up to that point, before it leaves.
What is the P site?
200
When no tryptophan is present.
What is the on position?
300
A double ringed nucleotide, such as A or G.
What is a purine?
300
A bubble made from the point of origin in replication, where replication takes place outward from that point.
What is a replication bubble?
300
The copy of DNA made from transcription.
What is mRNA?
300
A mixture of protein and RNA where translation takes place.
What is a ribosome?
300
When lactose is absent.
What is the off position?
400
The term to describe the the 5'-3'/3'-5' DNA structure.
What is anti-parallel?
400
The enzyme that adds nucleotides to a new DNA strand.
What is DNA polymerase?
400
The enzyme that makes the RNA.
What is RNA polymerase?
400
3 nucleotides that code for an amino acid.
What is a codon?
400
The operon that codes for the production of tryptophan.
What is the trp operon?
500
The bonds that hold the A's & T's and C's & G's together.
What are hydrogen bonds?
500
Where the enzyme adds nucleotides from on the new strand.
What is the 3' end?
500
Whe DNA sequence where the enzyme binds to start making RNA.
What is the promotor?
500
Where a new transcription RNA binds to join it's amino acid to the others.
What is the A site?
500
And enzyme that binds to an operon to inhibit gene expression.
What is the active repressor?
