Sex cells such as eggs and sperm only have one set of DNA.
The structures in the nucleus that contain DNA are chromosomes. Chromosomes are rod-like structures that are composed of DNA and protein.
A haploid cell is a cell which contains one set of DNA. Most cells have 2 full sets of DNA. Gametes (found in sex cells: sperm and egg cells) are gametes. It is important that they have only one set of DNA because, when the egg is fertilised, the two gametes fuse together to make a zygote with the full 2 sets of DNA.
so that there will be two sets of DNA ... one for each new cell. If the DNA doesnt replicate one new cell would have no DNA. and cells need DNA.
The semi-conservative process refers to DNA replication, where each newly synthesized DNA strand contains one original (parental) strand and one newly synthesized strand. This process ensures that each daughter cell receives a complete set of genetic information during cell division.
DNA is also known as deoxyribonucleic acid. It is found in the cell's nucleus as nuclear DNA. A genome is a set of DNA.
DNA
They are called chromosomes.Proteins are histone proteins.

Plasmic DNA is extrachromosomal DNA found in prokaryotes that replicates independently of the chromosomal DNA. Genomic DNA refers to the complete set of genetic material within the nucleus of eukaryotic cells or the nucleoid region of prokaryotic cells.
A set of genes derived from one parent is called a haplotype. Haplotypes consist of specific variations in DNA sequences that are inherited together. This genetic material represents a combination of alleles from one individual.
The mother's DNA is needed to perform a fully accurate paternal DNA test. If only one parent is included, this can only account for 50% or less of the child's DNA. So the results of just one parents DNA will not in any way give an accurate result.
The purpose of copying DNA is that, after mitosis, each daughter cell each has a complete set of DNA and is genetically identical.
