set of rules for how DNA/RNA codes for proteins
Genetic code
molecules that store genetic information
DNA
molecule involved in protein production
RNA
building blocks of DNA/RNA
nucleotides
repeating structure forming the sides of DNA/RNA
sugar-phosphate backbone
twisted ladder shape of DNA
double helix
DNA replication where each new DNA has one old and one new strand
semiconservative model
enzyme that builds new DNA strands
DNA polymerase
enzyme that joins DNA fragments together
ligase
opened section of DNA where replication occurs
replication bubble
Y-shaped area where DNA strands separate
replication fork
DNA strand synthesized continuously
leading strand
DNA strand synthesized in short fragments
lagging strand
segment of DNA coding for a trait or protein
gene
process of making RNA from DNA
transcription
process of making proteins from mRNA
translation
genetic code read in three groups of three bases
triplet code
three-base sequence on mRNA coding for an amino acid
codon
beginning stage of transcription
initiation
stage where RNA strand grows
Elongation
stage where transcription ends
termination
enzyme that builds RNA during transcription
RNA polymerase
DNA sequence where transcription begins
promoter
DNA sequence signaling transcription to stop
terminator
