In producing eggs and sperm why must DNA be divided to half its normal amount in somatic cells?
Tghe DNA in eggs and sperm must be divided in half so that when they later join together as a fertilized egg the egg has a normal amount of DNA
Is the amount of DNA in a human body cell the same as the amount of DNA in a human egg cell?
No. The amount of DNA in human sperm cells is half of the amount found in body cells.
What are gamets formed through?
Gametes are sex cells, formed through the process meiosis in which a cell divides to have half of the normal amount of DNA.
Why must cells undergo meiosis before they can fuse together to produce another organism?
Meiosis produces cells with half of the DNA of a normal cell so that when two cells that have gone through meiosis (like sperm and egg) are joined, the cell formed has the normal amount of DNA. If meiosis didn't happen each new organism would have twice as much DNA as it's parents.
How do haploid cells differ from diploid cells?
Haploid cells only have half the necessary amount of DNA (sex cells). Diploid cells have a full set of DNA (body cells).
When in a cells DNA content at its maximum?
In a normal cell, DNA content is at a maximum in G2 phase.
One difference between a cancer cell and a normal cell is that?
a. cancer cells divide uncontrollably. b. normal cells cannot make copies of DNA. c. cancer cells cannot make copies of DNA. d. normal cells divide uncontrollably. (A) cancer cells divide uncontrollably
Are DNA in muscle and skin the same?
DNA is found in two organelles: the nucleus and the mitochondria. The amount of nuclear DNA is fixed and does not vary from cell to cell, but the number of mitochondria can affect the amount of mitochondrial DNA.
How do DNA and cromosomes fit together?
Chromosomes are made of DNA. There is a huge amount of DNA in cells. DNA is typically present at a long chain of building blocks called nucleotides. Since long strands of DNA have to be stored in small spaces, they are tightly rolled and packed into structures called chromosomes
The cells hereditary material is called?
DNA
What is a cell that DNA is not found in?
DNA is found in every cell in every organism, even diseased cells.
What is the coded instructions inside cells called?
DNA (deoxyribonucleic acid).
