Genes — definition?
Sequences of nucleotides on DNA.
DNA — location?
Located in the nucleus.
RNA — role?
Messenger carrying genetic info from DNA.
Uracil — function?
Base in RNA replacing thymine.
Transcription — definition?
Synthesis of mRNA from DNA in nucleus.
mRNA — role?
Carries genetic info from nucleus to ribosome.
RNA polymerase — function?
Enzyme that synthesizes mRNA during transcription.
Stop codons — examples?
UAA, UAG, UGA do not code amino acids.
Genetic code — definition?
Mapping of mRNA triplets to amino acids.
Codon — role?
Specifies an amino acid or stop signal.
Start codon — sequence?
AUG, codes for methionine.
Stop codons — examples?
UAA, UAG, UGA, signal translation end.
Translation machinery — role?
Synthesizes proteins from mRNA templates.
Ribosome — structure?
Made of proteins and rRNA, with small and large subunits.
tRNA — function?
Transfers amino acids and recognizes mRNA codons.
Polyribosome — purpose?
Multiple ribosomes translating the same mRNA simultaneously.
Translation stages — sequence?
Initiation, elongation, termination.
Protein folding — process?
Polypeptide folds into functional structure.
Start codon — role?
Signals the beginning of translation.
Stop codons — examples?
UAA, UAG, UGA stop translation.
