Mitosis/Meiosis Test

QuestionAnswer
Where are chromosomes found? In the nucleus
What are chromosomes shaped like after Prophase? X's
What do we call loose unwound DNA? chromatin
What is the shape on DNA? Double helix
DNA has four nucleotide bases: adenine, thymine, guanine, and cytosine. How can you remember which ones pair up? Apples in the Tree (A with T) Cars in the Garage (C with G)
Each "rung" of the DNA ladder is made of? A pair of nucleotide bases
What is the function of DNA? It carries all our genetic info
What is the function of RNA? It is used in building proteins
Name the phases of the cell cycle? (I picked more apples than cherries) Interphase, prophase, metaphase, anaphase, telophase and cytokinesis
_________ makes exact copies. mitosis
________ makes sex cells. meiosis
Clone cells are called ______________ cells. DAUGHTER
True/False: Cells made by mitosis are called haploid. FALSE! CELLS MADE BY MITOSIS ARE DIPLOID. HAPLOID MEANS 1/2 THE NUMBER OF CHROMOSOMES. MEIOSIS MAKES CELLS THAT ARE HAPLOID.
Human cells, with the exception of sperm and egg cells, have _____ chromosomes. 46
The DNA is replicated during what phase of the cell cycle? Interphase
Mitosis is made up of what 4 phases? (Name them in order) Prophase, metaphase, anaphase, and telophase
Miosis is the dividing of the ____________________ into two new nuclei. NUCLEUS
Cytokinesis is the dividing of the ___________________. CYTOPLASM
What is a chromatid? 2 identical strands of DNA that are joined by a centromere
A change in the DNA during replication is called a mutation
If this were one side of a segment of DNA: AGCT WHAT WOULD THE OTHER SIDE BE? TCGA
Factors that control traits are called GENES
During what phase do chromosomes line up in the middle? Metaphase
During what phase do centromeres divide and chromosome halves move to each side of the cell? Anaphase
True/False: The two nuclei present in telophase (just before the cell actually splits) are identical. TRUE
What phase of the cell cycle is the longest? Interphase

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.
