Meiosis/Mitosis

Biology

QuestionAnswer
Sister chromatids They are identical copies of a chromosome.
The region of a chromosome where two sister chromatids are held together are called Centromere
Packages of DNA are called Chromosomes
DNA wound around proteins are called Chromatins
What is the name of the process in which two identical copies of DNA are made DNA Replication
G1, S, and G2 are known as interphase
The process of dividing the nucleus into 2 daughter cells is called mitosis
The process of separating the organelles and the cytoplasm is called cytokinesis
Mitosis has 4 stages (in order) Prophase, Metaphase, Anaphase, Telophase
Chromosomes become viable; nuclear membrace dissolves, centrioles start stretching spindles across cell is called prophase
chromosomes line up down the middle of the cell and attach to spindle at centromere is called metaphase
sister chromatids are pulled to opposite ends of the cell by the spindles is called anaphase
two new nuclear membranes form around each set of chromosomes; spindles dissovle is called telophase
the repeated sequence of growth and division during the life of a cell is called the cell cycle
A segment of DNA that codes for RNA and protein is called a gene
Reproductive cells are called gametes
Examples of organisms that reproduce assexually are amoeba, bacteria
Exmaples of organisms that reproduce sexually are plants, animals
Regular body cells with two complete sets of chromosomes are called diploid cell
Gametes which have half the normal number of chromosomes are called haploid cell
Chromosomes that are similar is size, shape, and kind of genes are called Homologous chromosomes
Males have _____ X and ______Y chromosomes 1 X and 1 Y
Females have ____X and _____Y chromosomes 2 X and 0 Y
A form of cell division that produces daughter cells with half the number of chromosomes as the parent cell Meiosis
What process occurs during prophase I of meiosis crossing-over
The union of the gametes during fertilization leads to the production of zygotes

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.
