Term
virus
Definition
A package of nucleic acid wrapped in a protein coat.
Term
bacteriophage
Definition
A virus that infects bacteria
Term
Deoxyribonucleic Acid (DNA)
Definition
A kind of nucleic acid, a polymer built from monomers called nucleotides
Term
Nucleotides
Definition
The building blocks (monomers) of the nucleic polymers
Term
Pyrimidines
Definition
Single-ring structures such as thymine and cytosine
Term
Purines
Definition
Double-ring structures such as guanine and adenine.
Term
double helix
Definition
two strands of nucleotides wound about each other; structure of DNA
Term
DNA replication
Definition
The process of replicating DNA by the double helix separating, each single strand acting as a negation.
Term
DNA polymerases
Definition
Enzymes that make the covalent bonds between the nucleotides of new DNA strands.
Term
RNA (ribonucleic acid)
Definition
Any nucleic acid whose sugar is ribose rather than the deoxyribose of DNA.
Term
transcription
Definition
Process by which a DNA template is used to produce a single-stranded RNA molecule
Term
translation
Definition
Converts nucleic acid language into amino acid language.
Term
Codon
Definition
a three-base "word" that codes for one amino acid.
Term
mRNA
Definition
A RNA molecule that is transcribed from a DNA template.
Term
RNA polymerase
Definition
A transcription enzyme that links the RNA nucleotides U and A together.
Term
intron
Definition
Internal non-coding regions inside RNA transcripts.
Term
exons
Definition
the parts of a gene that remain in the mRNA and will be translated.
Term
RNA splicing
Definition
The process where introns are removed and the exons are joined together.
Term
RNA splicing
Definition
The process where introns are removed and the exons are joined together.
Term
tRNA
Definition
Transfer RNA, translates the three-letter codons of mRNA to the amino acids that make up proteins.
Term
anticodon
Definition
The three bases that are complementary to a specific codon in the mRNA.
Term
rRNA
Definition
Ribosomal RNA, A complete ribosome has a binding site for mRNA on its small subunit and two binding sites for tRNA on its large subunit.
Term
mutation
Definition
Any
Term
mutation
Definition
Any change in the nucleotide sequence of DNA.
Term
mutagens
Definition
Physical or chemical agents that cause mutations
