Term
Virulent
Definition
Describes a microorganism that causes disease that is highly infectous; strictly refers only to viruses that reproduce by the lyctic cycle.
Term
Transformation
Definition
The transfer of genetic material in the form of DNA fragments from one cell to another from one organism to another.
Term
Bacteriophase
Definition
A virus that infects bacteria.
Term
SECTION 2
Definition
Term
Nucleotide
Definition
in a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base
Term
Deoxyribose
Definition
A five-carbon sugar that is a component of DNA nucleotides.
Term
Nitrogen Base
Definition
An organic base that contains nitrogen, such as a purine or pyrimidine; a subunit of a nucleotide in DNA or RNA.
Term
Purine
Definition
A nitrogenous base that has a double-ring structure; one of the two general categories of nitrogenous bases found in DNA and RNA; either adenine or guanine.
Term
Pyrimidine
Definition
a nitrogenous base that has a single-ring structure; one of the two general categories of nitrogenous bases found in DNA and RNA; thymine, cytosine, or uracil
Term
Base-pairing rules
Definition
The rules stating that cytosine pairs with guanine and adenine pairs with uracil in RNA.
Term
Complementary base pair
Definition
nucleotide bases on a chain of DNA.
Term
Base Sequence
Definition
Order of nitrogenous bases on a chain of DNA.
Term
DNA Replication
Definition
Process of making a copy of DNA.
Term
Helicase
Definition
Enzyme that separates DNA strands.
Term
Replication fork
Definition
Y shaped point that results when 2 strands (DNA) double helix separate so (DNA) molecule can be replicated.
Term
DNA Polymerase
Definition
Enzyme that catalyzes the formation of DNA molecule.
Term
Semi-conservative Replication
Definition
In each new DNA double helix, one strand is from the original molecule with one new one.
Term
Mutation
Definition
Change in the nucleotide base sequence of a gene or DNA molecule.
