Camponeschi

Camponeschi Genetics (targets 1a, 1b, 1c)

QuestionAnswer
cell cycle sequence of growth and division of cells
DNA Replication copying DNA so there are two exact sets of DNA - one set for each cell
What occurs during mitosis? The nucleus divides into 2 - one set of DNA is distributed to each new (daughter) cell
Do all cells go through a cell cycle? No - most cells do; however, some specific cells do not (nerve cells)
Why do cells go through a cell cycle? To make new cells to replace old cells; to make more cells to heal wounds or respond to an infection, to grow.
What is the purpose of the cell cycle (cell division)? to make new cells for growing, healing, and replacing old cells.
What percentage of your chromosomes (your genes) come from your mother? 50% (half)
What percentage of your chromosomes (your genes) come from your father? 50% (half)
The cell that carries the chromosomes from your mother to you is called a(an) egg
The cell that carries the chromosomes from your father to you is called a(an) sperm
What is the purpose of meiosis? to produce sex cells (sperm and egg)
describe the steps of meiosis. the chromosomes copy, nuclear membrane disappears, chromosomes line up, split, new nuclear membrane, cytokinesis. then nuclear membrane disappears, chromosomes line up, split, new nuclear membrane, cytokinesis.
How are mitosis and meiosis similar? they both make new cells, have DNA replication, chromosomes line up and split, cytokinesis.
Compare the cells made for mitosis and meiosis. mitosis make body cells; meiosis make sex cells. mitosis makes exact copies of original cell; meiosis makes different cells.
Compare the process of mitosis and meiosis they both make new cells, have DNA replication, chromosomes line up and split, cytokinesis. meiosis have two cell divisions; mitosis has one.
Compare the number of cells made for mitosis and meiosis. Mitosis make two new cells; meiosis makes four new cells.
Compare the percentage of chromosomes in the cells made from mitosis and meiosis. mitosis makes cells with 100% chromosomes of the organism; meiosis makes cells with 50% of the chromosomes.

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:
