Term
DNA Polymerase
Definition
An enzyme that catalyzes the elongation of DNA along the 3' end; adds nucleotides
Term
Aminoacyl Synthase
Definition
An enzyme that binds amino acids to the tRNA
Term
mRNA
Definition
What is transcribed from DNA, T becomes U
Term
UTR
Definition
Untranslted Region of DNA
Term
Lysine
Definition
positively charged Amino Acid
Term
Endergonic reaction
Definition
Non-spontaneous, yields nrg
Term
Exergonic Reaction
Definition
Spontaneous reaction where free nrg is relased
Term
Codon
Definition
A three nucelotide sequence (at/gc/u) that codes for an amino acid or termination signal.
Term
Anti-Codon
Definition
Complimentary codon from mRNA -- signals for amino acid
Term
FAD
Definition
flavin adenine dinucleotide (FAD), a redux agent. Oxidezed to FADH2, gains 2 E-
Term
N-terminus
Definition
Amine group, Signals start to Amino Acid
Term
C-terminus
Definition
Has an O=H, signals end of an AA
Term
Oxidative phosphorylation
Definition
NADH from krebs is oxidized, forms 34 ATP
Term
Substrate Phosphorlyaztion
Definition
A less effective way to create ATP from Phosphate in glycolosis
Term
Chemiosmosis
Definition
Pumps H+ ions across the membrane for ATP Synthesase
Term
ATP Synthesae
Definition
An enzyme that synthesizes ATP from H+ (the rotor) in cellular respiration
Term
Semi-Conservative Replication
Definition
The double stranded DNA helix replicates, Top strands is new and one is a copy. Watson and Crick
Term
Meselson–Stahl experiment
Definition
The experiment that supported Watson and Crick's semi-conservative hypothesie for DNA replicaiton. N15 and N14
Term
Hershey and Chase
Definition
Experiment in phage that showed DNA enters the cell rather than protein, suggesting DNA is hereditary
Term
[image]
Definition
Term
Polymerase
Definition
Enzymes that helps open up DNA during transcription
Term
Helicase
Definition
An enzyme that unzips the DNA strand making it available for template strands in replication
