What else can I help you with?
What would happen if cells with mutated DNA replicated?
Cancer.
Where are mitochondria constructed?
They are not built. They replicate themselves in cells
What is a characteristic of mitosis and not of meiosis?
The daughter cells produced are genetcally identical. A mitosis divides cells, which still contains the same number on chromosomes. In mitosis DNA is replicated once, and the nucleus divides once. In meiosis DNA is replicated once, but the nucleus is divided twice.
When and why does DNA need to be replicated?
When cells divide, the new cells produced must have a full set of genes in order to function correctly. Genes are made of DNA so it is necessary to replicate (copy) the DNA before the cell divides.
Why is it essential that DNA be replicated?
The cells that follow must be the same as the cells that they came from. You don't want a finger to grow out of your nose.
What would happen if cells with mutated DNA replicated uncontrollably?
If cells with mutated DNA replicated uncontrollably, it could lead to the development of cancer. This is because the mutations can cause the cells to grow and divide rapidly, forming tumors that can invade nearby tissues and spread to other parts of the body.
Do cells replicate or copy their DNA before going through meiosis?
Yes. The DNA is replicated during interphase before prophase I.
When is DNA duplicated and why is DNA duplicated?
DNA is duplicated during the S phase of the cell cycle, prior to cell division. DNA is duplicated to ensure that each new cell receives an exact copy of the genetic information, allowing for the accurate transmission of genetic material to the daughter cells.
How is recombinant replicated?
Recombinant DNA is replicated using host cells, typically bacteria or yeast, that have been engineered to contain the desired DNA sequence. These host cells are then grown in a lab setting under specific conditions that allow for the replication of the recombinant DNA. The cell division process allows for the production of multiple copies of the recombinant DNA.
What is a characteristic of meiosis and not meiosis?
The daughter cells produced are genetcally identical. A mitosis divides cells, which still contains the same number on chromosomes. In mitosis DNA is replicated once, and the nucleus divides once. In meiosis DNA is replicated once, but the nucleus is divided twice.
Why are all cells produced by mitosis exactly alike?
Becuase the DNA is replicated, so the two cells produced by mitosis are clones of eachother!
What is before DNA?
What is DNA replicated before?
