transfer RNA, transfers amino acids to ribosome to match them with code from DNA, w/ complementary anti codon , pairs with each codon, adding its amino acid to peptide chain
A three-nucleotide sequence of DNA or mRNA that specifies a particular amino acid of a polypeptide or termination signal; the basic unit of the genetic code, doesn't represent more than one amino acid
in the nucleus
where the DNA helix unzips and RNA nucleotides line up along one strand of DNA following base pairing rules
A specific nucleotide sequence in DNA that binds RNA polymerase and indicates where to start transcribing RNA
A special sequence of nucleotides in DNA that marks the end of a gene. It signals RNA polymerase to release the newly made RNA molecule, which then departs from the gene
takes place in the cytoplasm, ribosome attaches to mRNA and translates its message into a specific polypeptide aided by tRNA
interpreter, structure allowed for picking up appropriate amino acids and recognizing appropriate codon
base triplet on one end of tRNA, complementary to codon on mRNA, recognizes a particular code on mRNA
coordinates functioning of mRNA and tRNA to make polypeptide, consists of two subuits- each made of proteins and rRNA
mRNA, a specific tRNA, and ribosome subunits assemble and determine where translation will begin
2 steps of polypeptide initiation
mRNA binds to small subunit and initiator tRNA binds to start codon, anti-codon UAC binds to AUG, large subunit binds to small one ribosome, p site, holds growing polypeptide
On mRNA, the specific three-nucleotide sequenceAUG) to which an initiator tRNA molecule binds, starting translation of genetic information
codon recognition, peptide bond formation, translocation
each addition of an amino acid occurs in three step elongation process3 steps)
