the double helix
cell organelle which houses the DNA
What is the nucleus?
cell organelle responsible for translation
What is the ribosome?
Technique to amplify DNA.
What is polymerase chain reaction/PCR?
The enzyme which "unzips" the two DNA strands.
What is helicase?
a weak bond, disruptible by heat, that holds together two strands of DNA.
What is a "hydrogen bond?"
the normal process of duplicating DNA
What is DNA replication?
three types of RNA
What is mRNA, tRNA and rRNA?
First step in PCR in which two DNA strands are separated.
What is denaturation?
The strand in DNA which is built continuously.
What is the "leading strand?"
a pair of nitrogenous bases which link via hydrogen bonds
What is complementary?
amino acids are linked together to make a protein
What is translation?
triplet of nucleotides on the mRNA
What is a "codon?"
Second step in a PCR cycle in which primers attach.
What is annealing?
responsible for putting down complementary RNA nucleotides onto a DNA strand
What is "primase?"
the building blocks of proteins.
What are amino acids?
The process of constructing mRNA from DNA template.
What is transcription?
chemical bond linking together amino acids
What is a "peptide bond"?
Taq polymerase comes from this heat-loving bacterium.
What is "Thermus aquaticus?"
bits of DNA that are bonded together by DNA ligase.
What are Okazaki fragments?
A protein catalyst
What is an enzyme?
at this time of the cell cycle, DNA replicates
What is S/Synthesis phase (of interphase)?
These amino acids would be coded for in the mRNA strand:
UCC-AAA-GUG
(check a genetic code chart)
serine-lysine-valine
nucleotides, primers, sample DNA, buffers, and Taq polymerase.
What are the ingredients for PCR?
the direction in which DNA is built
What is 5' ----> 3'?
