Series of events that takes place from one cell division to the next

1. Chromosomes

   1. Located inside of the nucleus, these hold ALL of the genetic information

   2. Are made of:

The Cell Life Cycle includes

1. When cells get ready to divide, chromosomes 

duplicate themselves into two identical strands 

called

What is the process of cell division called?

What holds chromosomes together at the center?

What is the end result of mitosis?

1. The way a cell’s nucleus divides to form two 

identical nuclei

What phase follows metaphase in mitosis?

Mitosis occurs in

During which phase of mitosis do the chromosomes line up in the center of the cell?

This phase of mitosis is the longest

1. The centromere allows the chromatids to separate

2. The spindle fibers pull the individual chromosomes apart causing the cell to stretch more

Chromatids become visible under a microscope and the nuclear membrane starts to disintegrate

1. The chromatids line up across the center of the cell 

2. Spindle fibers attach to the centromere

3. The cell starts to stretch

Which structure is responsible for the separation of chromosomes during mitosis?

What are the results of Mitosis?

What is the term for the division of the cytoplasm following mitosis?

1. A new organism is produced with identical DNA of the parent organism

Meiosis occurs in

1. Occurs when the sperm and the egg join together

The cell that forms is then called a zygote

The event of two sex cells (gametes) joining together to make a new organism

1. Cells that have two sets of chromosomes (2n)

2. This is what mitosis makes 

3. Results in two identical daughter cells 

1. Gamete cells with only one set of chromosomes (n)

2. This is what meiosis makes

What phase does meiosis II NOT have?

What are the results of meiosis?

Who discovered DNA in 1952?

Who made a model of DNA in 1953?

What shape is DNA?

What nitrogenous base is NOT in DNA?

In DNA, Adenine pairs with?

In RNA, Adenine pairs with?

1. DNA unzips when it is about to be copied. 

2. The enzyme ___________________ does the unzipping by breaking the bonds between the nitrogenous bases

1. Determines characteristics such as hair color

1. It is made in the nucleus and modeled after DNA but it is only a half copy

2. It has the nitrogenous bases of Adenine, Guanine, and Cytosine but has Uracil instead of Thymine

1. Carries the code that directs the ribosome

1. Brings the amino acids to the ribosome

1. Makes up the ribosome

1. Any permanent change in the DNA sequence of a cell’s gene or chromosome

2. Can be caused by X Rays, Sunlight, and Chemicals

3. Can change the traits of an organism
