How does meiosis produce haploid gametes?
DNA doubles and cells undergo TWO ROUNDS OF DIVISION in meiosis the four daughter cells have half the amount of DNA as the parent.
Is the manipulation of the DNA of cells to change heredity traits or produce biological products?
Genetic engineering
When DNA is combined from two different sources what kind of organism does it produce?
If the two different sources of DNA are a sperm and egg cell, they produce a diploid organism, which means that it has two sets of chromosomes in its body cells.
Where are genes found in the nucleus?
in DNA which codes RNA which is then sent out the pores of the nucleus so it can produce proteins for cells.
Out of bacterial cells animal cells and plant cells which contain DNA?
Bacterial cells, animal cells, and plant cells all have DNA. DNA contains information for the cell on how to perform tasks. In plant and animal cells, DNA is contained in a nucleus, unlike bacterial cells where DNA is contained in a nucleoid.Hope this helped

Why is dna copied in mitsosis?
To produce exact copy of it for the formation of new body cells.
Why is DNA replication?
The replication of DNA forms new DNA which form new cells when put in the cells of new nucleus's. The body continuously needs to produce new cells through mitosis for growth and repair and therefore without DNA replication these new cells would not be able to be made, which are needed in the human body.
When chromosomes replicate they produce?
when the chromosomes are replicated the cells were about to divide into 2 cells (mitosis)

In the human pancreas acinar cells produce digestive enzymes and beta cells produce insulin because of what?
different parts of an individual;s DNA are used to direct the synthesis of different protein in different types of cells

Does all of the cells of a multi-cellular organism have the same DNA?
That is because there are different parts of DNA that become active depending on the functions and positions of different cells. For example, in a liver cell, the part of DNA that codes for the production of Insulin is not active, therefore, a hepatic cell can not produce Insulin. However, in some pancreatic cells that part of DNA is active and therefore these cells are able to produce Insulin. DNA is not fully activated in any cell.
Why do cells copy all the DNA chromosomes before dividing into two new cells?
In order for cells to divide and produce properly working cells, each resulting cell has to contain all the proper DNA. As such, the DNA is replicated so the cells each have the full DNA, so nothing is missing.
What directly controls how cells are formed and all their activites?

Why is it not possible to produce living cells from nonliving things such as rocks?
Non-living things do not have DNA, which is essentail for life.
