Transcription
The synthesis of RNA using DNA as a template
DNA Polymerase
Binds to site on DNA at the start of the gene being transcribed, unwinds double helix, links rna nucleotides with covalent bonds, detaches rna
Stability
The two strands of dna are only briefly separated, thus the bases are only briefly vaunerable to chemical changes that could cause mutation hence increases _____
Observable change
DNA → RNA → observable changes
Last
Transcription is the ____ stage in gene expression at which a gene can be switched on or off
Translation
Polypeptides synthesized through
One codon
3 rna bases
tRNA
Attaches to ribosome and turns each codon into an amino acid, then helping move the chain of amino acids to the next tRNA
