∙ 12y agothey get DNA from cells because the cell has a nucleus inside the nucleus u can find the chromosomes inside the chromosomes there is what we call the DNA inside it we can find the genes

∙ 10y agoDNA can be extracted from most cells by a simple chemical procedure: the cells are opened and the DNA is separated from the other cell parts.

What is the process by which a cell makes a copy of the DNA?
you would want to look into mitosis. This process will explain more about the copying of DNA.
Explain why DNA replication must occur before mitosis starts?
DNA replication mus occur before mitosis starts. Mitosis is another word for cell division and so there must be two copies of DNA for each cell at the end stage.
Biologists change the DNA code of a living organism through?
genetic engineering
How can cell culture be useful to biologists?
cell cultures help other cells reproduce so biologists can study them more
What DNA is found in the cell nucleus?
there is no DNA in the cell nucleus however the cell nucleus is important to replicating a cell in DNA strand. (it supprots the chromatin that replicates the DNA)
Why do all cells contain DNA Explain?
DNA is the blueprints of the cell. It will be like trying to write a book without anything to write about. The DNA tells the cell what to do by sending mRNA.
What is the name for biologists who study cells?
Cell Biologists is the name
What is the process by which a cell makes a copy of the DNA?
you would want to look into mitosis. This process will explain more about the copying of DNA.
What do cell biologists study?
Cell structure and organelles.
What is the process by which the cell makes the exact copy of its DNA?
you would want to look into mitosis. This process will explain more about the copying of DNA.
What do biologists look at when they classify an animal?
Biologists classify animals by their body structure, the way their body structure develops, and by their DNA.
Explain why cells are vital for life?
Cells are what keeps us alive. they hold our DNA and our DNA is what tells us apart. the cells are protected by the cell wall in plants and cell membrane in animals.
What are the substances that biologists call chromosomes?
chromosomes are chromatin fibre which contain DNA or genes that is seen only during cell division where chromatin fibres come together in bundles..
What technique do biologists use to separate on part of a cell from the rest of the cell?
Cell Fractionation.
What subset of DNA changes are analyzed by molecular biologists to determine evolutionary relationships?
Dna changes in important genes
What two things did this DNA model eventually help explain?
The type of cell it formes when the DNA is coppied for the hair mocules and the eye witch will forme often.
A cell would function without a nucleus explain your answer?
Most bacteria don't have a nucleus and they function using free floating DNA within the cell.
