Biotech and Meiosis

TermDefinition
cells having 2 copies of of each type of chromosome diploid
a cell of an organism that has half the number of chromosomes haploid
paired chromosomes with genes for the same traits in the same order homologous chromosome
male sex cell or gamete sperm
female sex cell or gamete egg
fertilized egg, diploid in number zygote
exchange of genetic material by non-sister chromatids during meiosis that results in a new combination of alleles crossing over
cell division in one diploid cell produces haploid cells which have half the number of chromosomes meiosis
haploid gametes fuse to produce a diploid zygote which then develops by mitosis to form a new organism sexual reproduction
nucleotides sequences from 2 different sources (species)are combined in the same DNA molecule recombinant DNA
small circular DNA molecules that replicate separately from eh bacterial chromosome Plasmids
cut DNA molecules at specific DNA sequences called restriction sites; usually makes many cuts yielding restriction fragments bacterial restriction enzymes
can produce many copies of a specific target segment of DNA polymerase chain reaction
uses a gel as a molecular filter to separate nucleic acids or proteins by size, electrical charge, and other properties gel electrophoresis
a living organism that contains recombinant DNA transgenic organism
somatic, diploid, chromosomes in pairs, mitosis body cells
sex cells, sperm and egg, haploid, chromosomes unpaired, meiosis gametes
chromosomes don't separate properly during meiosis non disjunction

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.
