The regular sequence of growth and division, DNA duplication that occurs in eukaryotic cells

• cell cycle

• cell replication

• cell growth

• cell DNA

What is the correct definition for mitosis?

• is the division of the cell nucleus and its contents.

• is the growth of cells between its different stages of life

• is the replication of a cell in prokaryotic cells

• is the division of a prokaryotic cell

What word best fits this definition: is the process that divides the cell cytoplasm.

• cytokinesis

• cytodivision

• cytocell

• cell cycle

A chromosome is defined as,

• is one long continuous thread of DNA that consists of numerous genes along with regulatory information

• only a portion of a chromatid

• a gene sequence of the DNA strand that communicates with the cell

• a protein strand that delivers nutrients to the cell

Each of your chromosomes is associated with a group of proteins called ______________. The DNA wraps around them at regular intervals.

• histones

• milestones

• protein stones

• herstones

Word that defines the "spaghetti" stage- the loose combination of DNA and proteins is called

• chromatin

• chromosome

• DNA cords

• histones

What is the definition of a chromatid?

• One half of a duplicated chromosome

• DNA sequence

• only the whole segment

• They produce all the proteins for the gene

What is the definition for a centromere?

• a region of the condensed chromosome that looks pinched, it holds the sister chromatids together at the center.

• a segment of the DNA

• the whole portion of the chromosome

• a protein that is located at the top of the chromatid

The ends of the DNA molecules form structures known as,

• telomeres

• telophones

• histones

• proteins

What state of mitosis is where the nucleus disappears, chromatin condenses into tightly coiled chromosomes. The first part of the word means before.

• prophase

• metaphase

• anaphase

• telophase
