Chapter 10 Vocab Flashcards
________ is a protein that is made by genetically engineered bacteria.
recombinant bovine growth hormone (rBGH)
_______ involves using the instructions carried by a gene to build a particular protein.
Protein synthesis
_______ is the basic building block of nucleic acids.
Nucleotides
_____, like DNA, is a polymer of nucleotides.
RNA
_____ is a sugar.
Ribose
______ is producing the copy of the required gene.
Transcription
_______ involves decoding the copied RNA sequence and producing the protein for which it codes.
Translation
______ is the copying of a DNA gene into RNA.
Transcription
The copy is synthesized by an enzyme called ____ ________.
RNA Polymerase
To begin transcription, the RNA polymerase binds to a nucleotide sequence at the beginning of every gene, called the _________.
Promoter
_______ carries the message of the gene that is to be expressed.
mRNA
_____ are sub cellular, globular structures.
Ribosomes
____ carry amino acids.
tRNA
_______ which is wrapped around many different proteins.
rRNA
As mRNA moves through the ribosome, small sequences of nucleotides are sequentially exposed. The sequences of mRNA are called _______.
Codons
_______ complement a codon on mRNA.
anticodon
Protein synthesis ends when a codon that does not code for an amino acids, called a ____ _____, moves through the ribosome.
stop codon
The ______ _____ shows which mRNA codons code for which amino acids.
genetic code
Changes to DNA sequence is called _______.
mutations
Due to the redundancy of the genetic code, a mutation that changes the mRNA codon from, say, ACU to SCC will have no impact because both of these codons code for the amino acid threonine. This is an example of _________.
neutral mutation
Changing the triplet groupings is called altering the ____ _____.
reading frame
All nucleotides located after an insertion or deletion will be regrouped different codons, producing a ____ _____ _______.
Frame shift mutation
______ ______ act like highly specific molecular scissors,
Restriction enzymes
Most restriction enzymes cut DNA only at specific sequences called ______
palindromes
