How many chromosomes are in cells formed during mitosis?
A cell undergoing mitosis has twice the usual number of chromosomes for that species. For example, human body cells have 46 chromosomes, but after DNA replication, which must occur before mitosis, a human body cell will have 92 chromosomes.
If an organism has a diploid or 2n number of 16 how many chromosomes do its sperm and egg cells contain?
Diploid cells contain twice the number of chromosomes as haploid cells. Sex cells (sperm and egg) are haploids. Therefore, if the diploid number is 16, sperm and egg cells must contain 8 each.
Why must a genetically engineered plasmid contain a genetic marker?
During the experiments for genetically engineered plasmids, a large number of cells are used because the frequency of insertion and recombination of the target gene is very low. This also generates a large number of cells in which the plasmid may not be taken up at all. In order to differentiate genetically engineered cells from normal ones, genetic markers are used which quite frequently are related to some physiological effect.
What must all cells contain?
A nucleus, A cell Membrane, Golgi- bodies, mitochondria, A Rough endoplasmic reticulum, a Smooth endoplasmic reticulum, chromosomes, A nucleolus, A nuclear membrane, and Cytoplasm.
Role of RBC lysis solution in DNA isolation?
When isolating DNA from blood, white blood cells (WBC's) are the target. This is because RBC's do not contain a nucleus and therefore do not contain DNA. The function of the lysis buffer is to help in the lysis (or breaking) of white blood cells. WBC's must first be lysed so that the DNA may be released from inside the cell.
At some time during their lives all cells must contain DNA. is this true?
At some time during their lives, all cells must contain DNA.
Why must their cells contain mitochondria as well?

What must a human zygote contain for making different types of cells in the human body?
I think it's stem cells
How does iron create red blood cells?
No - iron does not create them. However red blood cells must contain iron so it is needed for the cells to be formed.
Muscle cells use a lot of energy. Therefore what must they contain a lot of?
Mitochondria that produce ATP.
Why must Islamic believers go to Mecca once during their lives?
They must visit Mecca at least once in their lives unless they can not, this is the fifth pillar of Islam (Pilgrimage).
Do you see a nucleus in the red blood cells?
No - red blood cells do not contain a nucleus. This means that they cannot replicate, and must therefore be continuosly manufactured in the bone marrow.
Why must food be digested?
Digestion is necessary because for energy from the food to be released and carried into the cells in our body the food must be broken down into soluble molecules for it to diffuse into the cells. Then energy is released during respiration.
How many chromosomes are in cells formed during mitosis?

What happens if statement must contain an?
The if statement must contain else.
Why must a cell reduce the amount of genetic material during meiosis?
So that it can separate into more cells.
