History/Structure
Transformation in bacteria was shown by
Who is Griffith
This protein unwinds the DNA double helix
What is DNA Helicase
Regions of mRNA that will be cut out and are non coding
What are introns
The amino acid associated with the start codon (AUG)
What is Methionine (Met)
The Lac and TRP operons are examples of this type of system
What is a negative feedback system
Used bacteriophages to show protein coat stayed outside of nucleus following infection
Who are Hershey and Chase
Missing chunks of DNA found only on the lagging strand
What are Okazaki Fragements
Common promoter region is called
What is the TATA box
Ribosome recognizes this to bind to mRNA and begin translation
The most common phase to regulate gene expression is
What is transcriptional regulation
Discovered that DNA has a double Helix structure
Who is Rosalind Franklin
Prevent DNA double helix from zipping back up after they have been separated
What are single stranded binding proteins
These occur after the mRNA has been transcribed
What are post-transcriptional modifications
Type of RNA that carries amino acids?
What is tRNA
A mutation that occurs because of external factors
What is a spontaneous mutation
A deoxyribose sugar has this many carbons
What is 5
This protein lays down a primer to begin the synthesis of a new strand
Protein that transcribes the mRNA
What is RNA Polymerase
Theory that accounts for the redundancy in the codon table?
What is Wobble Theory
This results in an early stop codon
What is a nonsense mutation
At one end of the DNA strand is a 3' carbon on the deoxyribose sugar, at the other end is this
a free phosphate group on the 5' end
What is the Hayflick limit
Viruses use this protein to take RNA and make DNA
What is Reverse Transcriptase
Amino acids are linked by this type of bond
What is a peptide bond
When bacteria join together to share genetic information
What is conjugation
