TERM 1 DEFINITION 1
the inject door nucleus can direct the recipient egg to
produce normal tadpole, which is basically cloning
tadpole has full range of differentiated cells obtained
from original donor cell
TERM 2 DEFINITION 2
exposing of liver cell to a glucocorticoid hormone, for
example,the production of several specific proteins is
dramatically increase
Glucocorticoids release increase in the body during
starvation and crease the liver to produce glucose
So, the human brain and liver cells have different pattern
of protein
TERM 3 DEFINITION 3
a cell can control the proteins it makes by controlling six
steps show in the figure
TERM 4 DEFINITION 4
gel- mobility shift assay:
allows even trace amounts of a sequ ence-specificDNA-
bindingproteinbe readily detected
short DNA fragment of specific length labeled and mixed with
cells. free DNA move fast
loaded onto a polyacrylamide gel and subjected to
electrophoresis
It is native gel and protein would bind
TERM 5 DEFINITION 5
once a sequence-specific DNA protein has been purified, the
gel-mobility shift assay can be used to study the strength
and specificity of its interactions with different DNA
sequences

TERM 6

transcriptional activator

DEFINITION 6 is a protein that increases gene transcription of a gene or set of genes. the bindchromatinin the promoter region recruitRNA polymerase TERM 7 DEFINITION 7 used once the DNA sequence that a gene regulatory protein recognizes has been determine double-stranded oligonucleotide of the correct sequence is synthesized by chemical methods and linked to an insoluble porous matrix such as agarose attach beads to the determined DNA sequences ion interaction between the activator and repressor DNA TERM 8 DEFINITION 8 determining the sites on DNA that a given gene regulatory protein occupies proteins are covalently cross-linked to DNA in living cells cells are broken open, and the DNA is mechanically sheared into small fragments TERM 9 DEFINITION 9 Antibodies directed against a given gene regulatory protein are then used to purify DNA reversecross-linkeddenature DNA Used theremoved(isolated DNA) in PCR TERM 10 DEFINITION 10 promoter, where the general transcription factors and the polymerase assemble regulatory sequences to which gene regulatory proteins bind to control the rate of the assembly processes at the promoter
