DNA tech

DNA technology

TermDefinitionhints/examples
differentiated the process of a cell becoming programmed to become a cell with very specific structure and function to become 'different' stem cells produce differentiated cells
DNA analysis the process of comparing one DNA sample to other DNA samples
DNA sequence the specific order of nucleotides on any segment of DNA
fragments pieces of DNA nucleotide sequences - of different lengths
gel electrophoresis a process that separates DNA fragments based upon their size (nucleotide sequence length), separation of DNA is done by an electrical current passing through a gel "electro-" means electricity "-phoresis" means to separate
gene cloning the process of copying a specific DNA nucleotide sequence a 'clone' is a copy
gene therapy the process of replacing 'bad' DNA sequences (alleles) with 'good' DNA sequences (alleles) to improve an organism in some way
genetic engineering the process of adding new DNA sequences (genes) to an organism's own DNA
genetically modified organism (GMO) an organism that is the product of genetic engineering - has had 'foreign' DNA added to its DNA corn, soybeans, cotton
polymerase chain reaction (PCR) the process of reproducing small sequences of DNA artificially - mimics natures DNA replication process
preimplantation genetic diagnosis (PGD) to determine the genetic make up of an embryonic cell before inserting it into a uterus
recombinant DNA when two DNA sources are mixed to become one 'to recombine DNA'
reproductive cloning the process of producing a genetically identical organism
restriction enzymes proteins that are capable of cutting DNA at very specific nucleotide sequence sites - produced in nature by bacteria to 'cut up' viral DNA
sticky ends the nucleotide 'ends' created by restriction enzymes, the 'stick' to other complementary ends made by the same restriction enzymes
technology a tool to improve our conditions or to make life easier
undifferentiated cells that are not programmed to take on a specific structure and function, but instead produce cells that do stem cells themselves are undifferentiated

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
