Mostly to make new cells, but they also use it to make RNA which is a working copy. You copy the part of the DNA you want to work with into RNA. Then the RNA is moved to the part of the cell where it's instructions are needed and the amino acids it codes for are made. Eventually those amino acids can be built into proteins.
DNA is the master blueprint of your whole body. It codes for absolutely everything. This makes it very big (on a cellular level) and very, very important. Every cell needs its own copy and it stores that copy in the nucleus.
DNA is too big and too important for everyday use. So, RNA is used. With RNA you are only working with a copy so it is okay if something happens to it. You can always make another. Also. with RNA you only copy the section you need, so you don't have to haul out the whole genome just to make one enzyme.
DNA is only copied into DNA when the cell is splitting into a whole new cell. The it "unzips" its two halves and each cell gets half. When the two cells are totally split they go about replacing that half that they didn't get.
Obviously this is a pretty big understatement and simplification, but you get the idea. :)
The dna is a genetic material and is responsible for the hereditary traits so in order to keep the same quantity in the offspring's the DNA is replicated that is it is copied and distributed squally in their offspring's. The copies of DNA are very important from the poinf of view of evolution.
Cells before going to divide passes through a cell cycle. The cell grows in size while passing through this cycle. During inter-phase the cell grows and makes itself ready for division. It makes the exact copy of DNA by a process of replication. These copies of DNA are passed on to the cells that are formed as a result of cell division.
since DNA holds the genetic code that makes us what we are, DNA copying enable our body to reproduce new cells from old ones as well as reproducing the next generation.
as cell divides the dna also hav to divide to b transfferd in to newly formed cell so for that dna divides
if by any reason the cell does not copy its dna before division the resulting cell could a- be incompatible thus being destroyed automatically
b- be compatible dividing along with the complete one, creating a hybrid or
c- the resulting incompability could destroy both cells
What else can I help you with?
What would be the number of chromosomes in tr daughter cells if the chromosomes in the original parent cell did not duplicate?
46 (2n : 46), is the number r of chromosomes in tr daughter cells if the chromosomes in the original parent cell did not duplicate
What mitotic phrase does chromosomes duplicate itself to produce the chomatids?
The chromosomes duplicate itself during interphase
Why is duplication of chromosome required before mitosis?
Because every cell in the human body contains the formula for our chromosomes. If the chromosomes don't reproduce, then new duplicate cells cannot be formed.
In meiosis how often does cells duplicate their chromosomes?
In meiosis, cells duplicate their chromosomes only once, during the S phase of interphase, before the process begins. This duplication results in homologous chromosomes, each consisting of two sister chromatids. The subsequent two rounds of cell division (meiosis I and meiosis II) separate these chromatids and homologous pairs, leading to the formation of four haploid gametes.
What is the extra step in meiosis than mitosis?
In mitosis the chromosomes duplicate and the cell splits apart. But in meiosis, the cell does the same thing but this time, the daughter cells split again without duplicating the chromosomes. This causes those cells to have only half the amount of chromosomes. Hope i helped!
When do chromosomes duplicate in a cells life?
When there joined with a male chromosomes and a female chromosomes
In a cells life cycle when to chromosomes duplicate?
Interphase
What would be the number of chromosomes in tr daughter cells if the chromosomes in the original parent cell did not duplicate?
46 (2n : 46), is the number r of chromosomes in tr daughter cells if the chromosomes in the original parent cell did not duplicate
What is cell division and chromosome duplicaton?
when cells break apart and when the chromosomes duplicate
How many chromatids do you have when you duplicate your 46 chromosomes?
When you duplicate your 46 chromosomes, you will have 92 chromatids.
What mitotic phrase does chromosomes duplicate itself to produce the chomatids?
The chromosomes duplicate itself during interphase
Do chromosomes duplicate during interphase in the cell cycle?
Yes, chromosomes duplicate during interphase in the cell cycle.
Is duplicate or is duplicated?
When a cell duplicates, both the DNA and the chromosomes duplicate.
