Chromosomal basis of inheritance
sister chromatids separate in this phase of cell division
meiosis II
the number of DNA molecules present in each chromosome
one
term used for synthesis of RNA from DNA
transcription
the on-off switch in gene regulation
operator
term for the location of a gene on a chromosome
locus
a change in genotype and phenotype due to the assimilation of external DNA by a cell.
transformation
type of RNA molecule containing the anticodon
t RNA
this type of operon is usually off but can be stimulated to be on when a specific small molecule interacts with a different regulatory protein.
inducible operon
this gene located om the Y chromosome is required for development of the testes
SRY gene
viruses that infect bacteria
bacteriophage
term for non-template DNA strand
coding strand
inducer for the lac operon
allolactose
an X-linked recessive disorder defined by the absence of one or more of the proteins required for blood clotting
Hemophilia
the bonds that form the sugar-phosphate backbone of DNA
phosphodiester bonds
The DNA sequence where RNA polymerase attaches and initiates transcription
promoter
levels of this regulatory molecule, which also is a second messenger are high when glucose levels are low
cAMP
a linkage map is created using this data
recombination frequencies
proofreading of the new DNA molecule is a function of this enzyme
DNA polymerase
a sequence of 4 DNA nucleotides in the promoter region that is crucial for initiation of transcription
TATA box
the study of the inheritance of traits transmitted by mechanisms not involving the nucleotide sequence itself
epigenetics
