Term
DNA
Definition
Molecule of heredity, double stranded, subunit nucleotides
Term
Nitrogen bases
Definition
Adenine, Guanine, Cytosine, Thymine
(AG, CT)
Term
Chargraff's rule
Definition
Equal amount of A&T and C&G, A bonds with T, C bonds with G
Term

Definition
created the model DNA
Term
Watson-Crick
Definition
created the model DNA
Term
DNA Replication
Definition
Only occurs when preparing for cell division. Product = 2 double stranded pieces of DNA. 1 parent & 1 child strand
Term
Replication Process
Definition
1. dna helicase pulls apart the parental strand
2. dna polymerase moves along the open parent strand, matching free nucleotides in the cytoplasm with the complementary bases on the parent strand
3. dna ligase joins the daughter strand and the parent strand together.(semiservasive replication)
4. Newly synthesized double helices wind together
Term
Mutation
Definition
proofreading and repair process. environmental exposure increase the error rate.
Term
Point mutation
Definition
at only one point there's an incorrect letter match. (Base level)
Term
Frame shift mutation
Definition
insertion or deleting, everything after is affected. (Base level)
Term
Inversion mutation
Definition
has right info no the right order. (Chromosome level)
Term
Transclocation Mutation
Definition
two chromosomes swap over set of chromosomes. (chromosome level)
