Actually, you get 2 new chromosomes for each old chromosome. Each DNA molecule makes up 1 chromosome. When DNA replicates it splits into 2 strands. The replicated DNA is then coiled with proteins to give you the chromosome structures you're used to seeing. So total you will have 46+46 = 92 chromosomes in the nucleus. These will become evenly divided into 2 new daughter cells after mitosis.
The structure of DNA explains how it's replicated. Each strand has all the information needed to reconstruct the other half by base-pairing. During DNA replication, the molecule separates into two strands to produce two complementary strands following the rules of base-pairing. Each strand of the double helix serves as a model for the new strand.
Two copies of DNA are formed from parental DNA during replication .
Two Identical DNA molecules formed.

No molecules are visible to naked eye.Even to microscope,single molecule is not visible.
A single sugar molecule is known as a monosaccharide.
Replication in prokaryotes differs from replication in eukaryotes for prokaryotic chromosomes have a single origin of replication, whereas eukaryotic chromosomes have many. Eukaryotes and prokaryotes for replication double stranded DNA, four kinds of dNTPS, primers, and origins.
role of ssb protein in dna replication is when the double stranded dna is brought in the single stranded form during replication the ssb bind to the single stranded dna so that the ss dna remain in the the single stranded form and when replication process is completed these protein get dissociated from the dna
DNA replication uses thymine.

the bacterium copies its single chromosome
Evolution begins with self replication. Evolution on Earth began around four billion years ago. We don't have any record of that long lost microscopic beginning, but it may have been a single molecule that could make copies of itself.
