Checkpoint genes encoding protein that stimulate mitosis are called what?
proto-oncogenes
What do checkpoint genes do?
check to make sure if the cell is correct/right/ready to move on to the next stage.
Why do the function of cell differ mitosis?
the renetic genes are similar
Differences between parent and daughter cells in mitosis?
Nothing, they are identical in genes.
What are two differences between mitosis and meiosis?
1: Mitosis and Meiosis are the two ways by which cells reproduce.2: Mitosis and meiosis produce fresh new cells based on their parent cells' genes.
Does mitosis allow genes to move from one chromosome to another?
No. Mitosis produces an exact copy of a cell's DNA. Meiosis allows genetic transfer to occur.
Are genes located on the autosomal called sex linked genes?
No, genes located on the autosomes are not called sex linked genes. Only genes located on the sex chromosomes are called sex linked genes.
Why is accurate replication of genes important for mitosis?
In order to produce identical genome in daughter nuclei
What Mendel called factors are today called genes?
GENES
How do eukaryotic cells make more cells?
Cell can make more cells via two processes. The first is called mitosis: a process which creates two identical cells. Both eukaryotic and prokaryotic cells can undergo mitosis. The second is meiosis: a process which produces reproductive cells in sexually reproducing eukaryotes. When a cell becomes cancerous, one or more mechanisms in the cell that control mitosis breaks down. This occurs due to a mutation in the cell's DNA. The genes in which a cancer-causing mutation can occur are either called proto-oncogenes or tumour suppressor genes. When such a mutation occurs in a proto-oncogene they become activated and become oncogenes. The product of oncogenes promote uncontrolled mitosis, hence the name onco(cancer)-gene. Again, as the name suggests, tumour suppressor genes have some role in suppressing cancer. Tumour suppressor genes are regulators of mitosis. When a cancer causing mutation occurs in a tumour suppressor gene, the product of the gene becomes disfunctional or are not produced altogether.
Reproduction by mitosis duplicates?
Haploid cells use mitosis for asexual reproduction..Meiosis is used in animal cell division to create haploid cells for reproduction
Why is gene regulation an important issue in gene therapy?
several genes may play a part in turning other genes on and off. For example, certain genes work together to stimulate cell division and growth, but if these are not regulated, the inserted genes could cause tumor formation and cancer
