notes on transcription + translation
Term | Definition |
---|---|
polypeptide | string of amino acids |
proteins | made up of amino acids; assembled on a ribosome |
DNA replication | DNA double helix unwinds, becomes single-stranded, new strand forms using A-T, C-G, used to prepare for cell division, whole genome copied or replicated |
DNA | double stranded, deoxyribose sugar, bases = C, G, A, T |
RNA | single stranded, ribose sugar, bases = C, G, A, U |
transcription | RNA forms base pairs with DNA |
primary transcript | length of RNA that results from the process of transcription |
mRNA | type of RNA that encodes information for the synthesis of proteins and carries it to a ribosome from the nucleus |
RNA polymerase | complex of enzymes with 2 functions, unwind DNA sequence and produce primary transcript by stringing together the chain of RNA nucleotides |
exons | coding regions |
introns | non-coding regions |
translation | second stage of protein production; mRNA on a ribosome; tRNA brings amino acids to the ribosome |
tRNA | transfer RNA; bound to 1 end anticodon on the other end complements mRNA codon |
tRNA function | amino acids must be in the correct order for the protein to function correctly; tRNA lines up amino acids using mRNA code |
