Chapter 6 Flashcards: DNA and the expression of genes
Flip
Over
Hint
the full set of genetic material present in an organism
genome
Hint
a sequence of nucleotidea which codes for a protein
gene
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
a phenotype is exhibited from a gene when transcription is followed by translation
expression
Hint
the enzyme involved in transcription
RNA polymerase
Hint
specific region on the DNA where RNA polymerase binds to start transcription
promoter site
Hint
scribe
a person who copies documents (usually in the same language,
e.g.
from oral to written form)
[definition]
Hint
molecules that carry amino acids and bind to codons on the mRNA during translation
tRNA
Hint
triplet of 3 nucleotides on the mRNA that codes for an amino acid
codon
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
