Q

What does the golgi body (also called golgi complex) do?

A

It processes and “packages” proteins and lipid (fat) molecules for use in other places inside and outside the cell.

Q

What happens during metaphase?

A

The chromosomes line up at the equatorial plate. The centrioles attach to the centromeres of each chromosome.

Q

What happens in Anaphase of mitosis?

A

The great split! The centrioles pull each chromatid.

17
Q

What happens during telephase? Mitosis only.

A

New nuclei form each with two complete sets of chromosomes. Cytokinesis divides cell into two daughter cells.

18
Q

What is cytokinesis?

A

The division of cytoplasm

19
Q

What is diploid versus haploid?

A

A diploid (di meaning 2) is a pair of homologous (same) chromosomes. A haploid is one single ho.

20
Q

How does synapsis play a role in reproduction?

A

Synapsis is the phenomenon in which homologous pairs line up next to one another (i.e. Father’s Chromosome 1 and Mother’s Chromosome 1)

21
Q

In mitosis you start with one cell and how many cells do you end up with?

A

2

22
Q

After meiosis ine cell turns into how many cells do you end up with?

A

4

23
Q

What is a zygote?

A

A diploid cell (having a complete set of choromosomes) resulting from the fusion of two haploid gametes; a fertilized ovum.
It is still a single cell!

24
Q

Gametes have ____ the number of chromosomes as the original cell.

Half
Double
Triple

A

Half

25
Q

What is an autosome?

A

Any chromosome that is not a sex chromosome.

26
Q

What is a covenant bond?

A

A covalent bond is a chemical bond where the electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

27
Q

Long chains of monomers are called what?

A

Polymers!
