Bio Test

Mitosis, Meiosis, Genetics

TermDefinition
cell division that our body cells or somatic cells undergo Mitosis
cell divisions that produce reproduction cells or gametes (sperm or egg) Meiosis
study of heredity Genetics
cell that has one set of chromosomes or one set of genes (n) Haploid
cell that has two sets of chromosomes (chromosomes still in pairs) (2n) Diploid
haploid cell egg and sperm (reproductive cell) Gamete
diploid cells that are our body cells anything there than egg or sperm Somatic cell
diploid cell fusion of egg and sperm Zygote
cell grows Interphase- G1
DNA replicates Interphase- S
produced anything needed for cell division Interphase- G2
trying to prevent cancer “guardian angel of cell division” P53 gene
cell divion that prokaryotes undergo like bacteria Binary Fission
rod shaped structure that contains DNA histone protiens Chromosomes
replicated chromosomes two strands help together by a centromere Sister Chromatids
similar in size shape and traits not identical Homologous Chromosomes
mass of cells that are non-cancerous Benign Tumor
mass of cells and tumors that are invasive metastasis Malignant Tumor
pinching of the cell membrane during cytokinesis Cleavage Furrow
forms before the cell wall during cytokinesis Cell Plate
protein that holds two sister chromatids together Centromere
microbulus that separate sister chromatids during cell division Spindle Fibers
number of chromosomes in a human egg or sperm 23 Chromosomes
number of chromosomes in a zygote, fertilized egg or a human body cell 46 Chromosomes
the swapping of genes of non-sister chromatids in the homologous pairs Crossing-Over
the replicated homologous pairs lie close together that becomes a tetrad (during Prophase I) Synapsis
diagnostic tool used during the 16 week of pregnancy to determine the health and sex of the baby Amniocentesis
fusion of egg and sperm fertilization
What is the main goal of Mitosis? to have identical daughter cells identical to each other and identical to the parent
What is the goals of Meiosis to seperate the pairs of chromosomes - want one member of each pair

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.
