Explanation:
About 95 percent of the time, Down syndrome is caused by trisomy 21 — the person has three copies of chromosome 21, instead of the usual two copies, in all cells. This is caused by abnormal cell division during the development of the sperm cell or the egg cell.
Answer:
DNA replication is the process by that DNA make a copy to the cell division.
Explanation:
- DNA replication is the double structure to the DNA molecule,it is biological process.
- DNA replication molecule the serve that template for the production to referred conservative replication.
- DNA replication occurs living the biological property of division and they performed complementary stand.
- DNA replication to that begin the specific location and origins in the genome, and growing from the origin.
- DNA replication is performed to the outside and artificially to the cell,in the DNA molecule.
- DNA replication is single strand by the DNA chain of nucleotide function, DNA contain the sugar .
- DNA replication is the basis of single strand to 3 prime and 5 prime end, these refer to the carbon atom in the chain attaches.
- DNA replication allow the strand to the one another strand to used in partner strand.
- DNA replication is to matched in the template strand at one time with the creation of bonds,they high energy bonds.
