(CH 11) ______ interacting with ______ turn ______ genes on or off in response to environmental changes
Proteins, DNA, prokaryotic
gene is ____ ____ when it is being transcribed to produce mRNA that is translated to make its corresponding protein
active repressor binds to the operator. inducer binds to and inactivates the repressor
includes three adjacent genes for lactose-utilization enzymes. Promoter sequence where RNA polymerase binds
lactose (lac) operon
the ________ of lactose in the repressor causes the repressor to bind to the operator and prevent RNA polymerase transcription
three adjacent genes for lactose-utilization enzymes, operator sequence where a repressor can bind and block RNa polymerase action
results from the expression of different combinations of genes. involves cell specialization, in both structure and function. Controlled by turning specific sets of genes on or off.
multiple levels of folding and coiling that is undergone by eukaryotic cells. helps with gene expression. Can prevent transcription
name for one X chromosome not being active in each somatic cell of a female mammal. Responsible for tortoiseshell fur coloration in heterozygous female cats
In female mammals one of two X chromosomes is highly _____ and transcriptionally ______
X chromosomal inactivation occurs _____ in embryonic development, and ____ cellular descendants have the same inactivated chromosome
process of root cells cultured in nutrient medium, cell division within culture, plantlet, then adult plant.
plant cloning proves that differentiated cells may retain (all, some, or none) of their genetic potential
can be used to clone animals. replacing the nucleus of an egg cell or zygote with a nucleus from an adult somatic cell
take blastocyst and implant it in female species' uterus. implant embryo in surrogate mother for development. new animal will be genetically identical to nuclear donor
used to produce animals with desirable traits. animals could then produce agricultural products, therapeutic agents, or restore endangered animals
remove embryonic stem cells and grow in culture for medical treatments. induce stem cells to differentiate
first person to connect a job with the onset of a cancer (believed chimney sweeps developed scrotum cancer b/c of the dust getting in the skin)
rare form of cancer that is in the eye and can spread to the brain, traveling through the optic nerves to the back of your brain. Happens in 1 in 20,000 children. Showed cancer could be genetic b/c occurred 3 times in one family.
can cause skin cancer from being exposed to harmful rays through machinery. Marie Cury
