genetic primer
a cell is
basic building blocks of all living things
genes are
the basic units of heredity that provide instruction. They are bits of biochemical info
biotechnology
collection of scientific techniques that use living cells and molecules to make products and solve problems.
enucleated
the nucleus is removed from the cell
scaffold
parts of a cell
plasma membrane, cytoplasm, cytoskeleton, ER, Golgi apparatus, lysosomes, mitochondria, ribosomes,
epigenetics are
the study of how the expression of genes can be turned on or off, studies how these changes happen in your life and how its passed down.
transgenic animals
species that carry one or more genes from another species. Are important tools for research.
embryo
unhatched or unborn offspring
extracellular matrix
surrounds and supports the cells that form tissues and organs in the body. created and maintained by cells.
nucleus does what
serves as cells command center, is the house of DNA
genetic mapping
genetic maps that identify and chart the position of known genes and markers.
transgenic organisms
organisms that contain another species genes withit in their chromosomes like bacteria.
blastocyst
embryo within the first 5 days of fertilization.
totipotent
give rise to all other cells as well as embryonic tissues (placenta stem cells).
what is DNA
its the hereditary material in humans and other organisms. made up of nucleotides
chromosomes
long continuous pairs of DNA. we have 46 or 23 pairs.
examples of transgenic animals
mice, sheep, goats, cows, chickens, pigs, rabbits, fish.
reproductive cloning
the reconstituted embryo is placed into the uterus of a surrogate female.
pluripotent
genetic engineering
technique used by scientists to manipulate genes.
genotype
is the genetic code for a trait
benifits
they are animal modules, transgenic animals produce substances used in medicine, organ doners, livestock improvement.
theraputic cloning
embryo undergoes cell division until blastocyst stage(in vitro). Then embryonic stem cells are placed in tissue culture.
multipotent
