Cell Cycle and DNA Review

What is Prophase?

When the DNA replicates and grows to prepare for mitosis

When a new membrane forms

Chromosomes line up in the middle of the cell

When chromosomes become visible and the nuclear membrane desolves

What is Metaphase?

Where chromosomes are pulled apart

When chromosomes line up in the middle of the cell

When the rest of the cell divides into two daughter cells

What is Anaphase?

When the DNA replicates

When new membrane forms two sets of chromosomes

Chromosomes are pulled apart

What is Telophase?

When a new membrane forms two sets of chromosomes

Lol

Chicken

How do daughter cells compare to the parent cells?

They become visible

They become exact replicates of the parent cell

They make their own food

During mitosis, which structure divides?

The cell

The nucleus

What is the structure of chromosomes?

A double helix shape

Single stranded

A condensed DNA molecule

How many chromosomes do normal humans have?

How do sperm and eggs cells compare to normal human cells?

Because they have 23 chromosomes

Because they have 14 chromosomes

What is DNA and where is it located?

DNA is a protein and is found in the mitochondria of a cell

DNA determines all your physical features and is located in the nucleus

DNA is a chromosome that makes protiens

What does DNA code for?

Proteins

Chromosomes

Energy

A always matches with _____ and C always matches with _____

Thymine

Guanine

Uracil

Adenine

Why must the DNA be replicated before the cell can divide?

So it can make a copy of DNA

DNA must be replicated before the cell can divide because every new cell needs a copy of the DNA

Because it needs to make proteins

Because it just does

What are the differences between DNA and RNA?

DNA instructs everything in the cell while RNA makes it happen

DNA is double stranded and RNA is single stranded

DNA needs to replicate, while RNA doesn't

RNA uses Uracil instead of Thymine

What is the order of the cell cycle?

Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinisis

Prophase, Anaphase, Metaphase, Telophase, Cytokinisis, Interphase

Metaphase, Prophase, Telophase, Interphase, Anaphase, Cytokinisis
