What is the definition of the word mitosis?
What is the process by which the duplicated contents of the cell’s nucleus divide into two equal parts.
200
How many chromosomes do humans usually have?
What is 46 chromosomes 23 pairs of two.
200
What is the definition of the cell cycle?
What is the cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells.
200
What is the definition of sexual reproduction?
What is the production of new living organisms by combining genetic information from two individuals of different types (sexes).
400
During which phase of mitosis is DNA replicated?
What is the S phase or the synthesis phase.
400
What is the definition of chromosome?
What is chromosomes come in pairs one set from the mother the other set from the father.
400
The process of a cell committing suicide by activating an interstellar death program?
What is cell death.
400
What does the word DNA mean?
What is deoxyribonucleic acid.

Name the four basic stages of phases of mitosis?
What is Prophase, metaphase, anaphase, and telophase.
600
What does X/Y pair chromosomes determine in humans?
What X chromosomes are for females and the Y chromosomes are for males.
600
In the cell cycle, this stage is when DNA is duplicated and proteins are made?
What is interphase.
600
Why is X chromosome bigger then the Y chromosome?
What is the additional genes in the X chromosome.

How does cytokinesis differ in plant and animal cells?
What is the main difference is how they form the daughter cells during cytokinesis, during that stage, animal cells form furrow or cleavage that gives way to formation of daughter cells. Due to the existence of the rigid cell wall, plant cells don't form furrows.

What is the genetic disorder by having an extra 21 chromosome?
What is Down-Syndrome.
800
This picture shows what that is being pulled apart from the sister chromatids?
What is anaphase.
800
What are the 4 DNA nitrogenous that have the same base?
What is Adentine, Cytosine, Thymine, Guanine.

What is the process of mitosis?
what the process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. If not corrected in time, mistakes made during mitosis can result in changes in the DNA, that can potentially lead to genetic disorders.
1000
What are chromosomes made up of?
What is DNA and proteins.

Describe briefly how the cell cycle works?
What is the cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

What is nucleotides.
