Operon
Name given to a unit of a bacterial chromosome that controls the expression of a specific set of genes
In prokaryotes, the production of a single RNA transcript for a group of related genes is under the control of
Operator
acts as an on/off switch.
Regulatory genes code for
repressors
Repressors block binding of RNA polymerase by attaching to
Operators
At one point, you were just an undifferentiated, single cell. You are now made of many cells; some of these cells function as liver cells, some as muscle cells, some as red blood cells, while others play different roles. What name is given to the process that is responsible for this
Cellular Differentiation
The process by which genotype becomes expressed as phenotype is ______.
Gene Expression
Bacterial RNA polymerase binds to the ______.
Promoter
Reproductive cloning
replacing nucleus of an egg cell with nucleus of and adult somatic cell, results in birth of new animal.
Proto-oncogene
normal gene with potential to become genes that cause cancer
Nuclear transplant
replacing nucleus of an egg cell w/ nucleus from different cell from different adult body
Embryonic stem cell
from blastocysts lead to all specialized cells in body; can be put in particular culture and generate different parts of body
Adult stem cell
cells in adult tissue and replace some of body’s cells (can use for medicine)
Regeneration
regrowth of lost body parts (lizard tail)
Oncogene
genes that cause cancer
Therapeutic cloning
to produce embryonic stem cells
