lecture 1-15-16 Flashcards
a ____ specifies a particular amino acid
codon
transfer RNA carries an amino acid to the mRNA and Ribosome by using its _________to find a matching mRNA codon
anticodon
set of rules relating particular mRNA codons to particular amino acids; redundant and universal
genetic code
advantages of “pharming”
makes complex human proteins
less expensive
makes large amount of protein
clinically equivalent
genes provide instructions to make proteins
gene expression
amino acid sequences determine the shape and the function of _________
a protein
a protein is made of up of a chain of
amino acids
________amino acids tend to be found folded inside a protein, whereas ______amino acids interact with water on the outside of the protein
hydrophobic; hydrophilic
what determines a protein’s function
the three dimensional shape of the folded protein
what determines how a protein folds
the interaction of the side chains of each individual amino acid
which of the following accurately describes amino acid side chains
they provide unique functions to a folded protein
heating a protein can cause it to denature or unfold. what do you think would happen to the function of a protein in a denatured state
the protein would not be functional because the three dimensional shape dictates protein’s function
what is the final product of gene expression
a protein
_______is the product of transcription, and _______is the product of translation
mRNA; a protein
disease of unregulated cell division; cells divide inappropriately and accumulate, in some instances forming a tumor
cancer
