Chapter 5 Flashcards: DNA, Gene Expression, and Biotechnology
Flip
Over
Hint
the full set of DNA present in an organism
genome
Hint
alternative versions of a gene that are inherited from each parent
alleles
Hint
an individual's alleles (genetic makeup), inherited from its parents
genotype
Hint
an observable trait of an individual, determined by its genotype
phenotype
Hint
pheno
appearing, seeming (phenomenon is something observed)
[prefix]
Hint
non-coding regions that occur occur within genes
introns
Hint
the enzyme involved in transcription
RNA polymerase
Hint
specific region on the DNA where RNA polymerase binds to start transcription
promoter site
Hint
triplet of 3 nucleotides on the mRNA that codes for an amino acid
codon
Hint
molecules that carry amino acids and bind to codons on the mRNA during translation
tRNA
Hint
a change in the DNA sequence of an organism
mutation
Hint
insertions or deletions of nucleotides can lead to this type of mutation
frame-shift mutation
Hint
technology used to amplify small amounts of DNA, using DNA polymerase
PCR
Hint
amplify
increase, enlarge (an amplifier increase a signal to speakers for sound production)
[definition]
Hint
an enzyme that cuts DNA molecules at specific restriction sites
restriction enzyme
Hint
surrogate mother
a female who is implanted with an embryo created by in vitro fertilization
[definition]
Hint
non-coding regions of the DNA that can be used to uniquely identify an individual
short tandem repeats
Hint
apparatus to separate DNA fragments based on fragment size
gel electrophoresis
Hint
technology using gel electrophoresis and restriction enzymes to identify individuals by their DNA fragments
DNA fingerprint
