Translation and Mutations
UAA, UAG, UGA
Amino acids are bonded together as _____ _____ which fold into proteins
mRNA read from _prime to_prime
One of a ribosome's three binding sites for tRNA during translation. This site in the ribosome holds the tRNA carrying the next amino acid to be added to the polypeptide chain.
one of a ribosome's three binding sites for tRNA during translation. It holds the tRNA carrying the growing polypeptide chain.
the first phase of transcription; RNA polymerase binds to DNA @ the promoter, and unwinds the double helix
addition of amino acids to the polypeptide chain; continues until it reaches a stop codon
last phase of transcription, stop codon
many proteins need to be chemically modified and folded, some may need to be cut into segments or have parts removed
cause frameshift, nucleotides added to the sequence
cause frameshift, nucleotides skipped in a sequence
correct nucleotide is replaced with an incorrect nucleotide
Missense and Nonsense are examples of _____ ________.
change in an important amino acid
change in an amino acid to stop codon
larger scale mutations, includes deletions, duplications, inversions and translocations
taking a piece and moving it to a different chromosome
a kind of mutation in which the order of the genes in a section of a chromosome is reversed
