DNA Replication
DNA strands are made in this direction
What is 5' to 3'
These are the three different "stops" at a ribosome
What is APE? Aminoacyl, Polypeptide, and Exit?
This method is used to magnify DNA strands
PCR (polymerase chain reaction)
Beadle and Tatum hypothesized this
What is the "one gene, one enzyme" hypothesis?
These are protein coding regions of the transcript
This enzyme unwinds the DNA
What is helicase?
This step of protein synthesis comes before translation.
These are the three steps of PCR
Denaturation
Annealing
Extension
They exposed neurospora to this to cause mutations.
What is radiation?
This can result in different expression of genes due to splicing
what is alternative splicing?
DNA is replicated this often
What is every cell cycle
This is the role of tRNA
What is to carry amino acids to the mRNA strand
why do we use PCR
to copy certain pieces of DNA
They did another experiment with the intention to determine this
Which metabolic pathway was broken in each mutant?
A RF of less than 50% indicates these
What are linked genes?
These are the three steps of DNA replication
What are initiation, elongation, and termination?
these are the end products of protein synthesis
what is a polypeptide chain
Large parts of DNA stay towards this charge
What is a negative charge?
They used these mediums
What are minimal and complete mediums.
This causes "derivatives" of stem cells
What is cell specialization?
Human cells' DNA take this long to replicate
What is 6-8 hours?
EPA occurs in the
ribosomes
This is the hottest step of PCR
The spores with this label were unable to grow on a minimal medium
What are "nutritional mutants?
These get spliced out during RNA splicing
What are introns?
