Central dogma
definition:
dna to rna to protein
transcription
definition:
dna to rna
translation
definition:
rna to protein
there are three kinds of RNA
mRNA
convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression
tRNA
link between amino acid sequence and mRNA
rRNA
link between amino acid sequence and mRNA
mutations
insertion: adding one codon
substition: swapping out a molecule with a different
deletion: taking off one codon
gene sequence
the process of determining the precise order of nucleotides within a DNA molecule
