Q

How is plant cell mitosis different from animal cell mitosis?

A

Plant - NO cleavage furrow, a cell plate forms to divide the cell

Animal - YES cleavage furrow, the cytoplasm is pinched to split the two cells

13
Q

A mutation that involves the substitution of one nucleotide (letter) for another

A

Point Mutation

14
Q

A large mass of cancer cells

A

Tumor

14
Q

Who or what does cancer affect?

A

All multicellular organisms

15
Q

What are three reasons a cell would have to divide?

A
  1. DNA Overload
  2. Cannot take in enough materials (resources) fast enough
  3. Cannot get rid of waste fast enough
16
Q

Which phase of mitosis is being described:

  • Chromosomes become visible
  • Nuclear membrane dissolves
  • Spindle forms
  • Centrioles move to poles of the cell (opposite ends)
A

Prophase

17
Q

What are the three types of RNA?

A

mRNA, tRNA, rRNA

18
Q

During metaphase…

A
  • The chromosomes line up in the middle of the cell
  • The spindle fibers attach to the centromeres
20
Q

True or False: Volume increases slower than surface area

A

FALSE.

Volume increases FASTER than surface area!

22
Q

The uncontrolled growth and reproduction of a cell

A

Cancer

24
Q

3 letters in a row on mRNA is known as a ____ and is used to code for proteins

A

Codon

27
Q

The RNA that maintains (makes up) the ribosome is ____

28
Q

What allows cells to specialize?

A

Gene Regulation

(know this!)

29
Q

What are the two ways cells regulate cell division?

A
  1. Through internal regulators (cyclins)
  2. Through external regulators (touch)
30
Q

mRNA molecules are made from DNA molecules during _____ in the _____

A

Transcription in the Nucleus

31
Q

Which type of RNA copies the DNA from the nucleus and carries the information to the ribosome?

A

mRNA
m = message

33
Q

This is a picture of what molecule?

A

DNA

34
Q

How should the number of purines and the number of pyrimidines compare?

A

The number of purines should be equal to the number of pyrimidines
