5'-3' : One strand
Two - the leading strand and the lagging strand.
DNA replication requires the opening of the 'zipped up' DNA strand. This is so a 'new' strand of DNA can be inserted and have a template strand to 'read' off. DNA polymerase analyses the bases on the template strand and adds each complementary base to synthesise the 'new' strand. In order for DNA polymerase to be able to do this the DNA has to be opened up by helicase to reveal the bases of the template strand. The unzipping of the DNA by helicase forms the replication fork. Thus the function of the replication fork is to reveal template strands for DNA replication to actually occur.
a cable.
i believe its 2. correct me if im wrong
DNA consists of two strands of nucleotides twisted into a double helix.
Two - the leading strand and the lagging strand.
At the beginning of DNA replication there are two strands of DNA nucleotides.
because it just is

an error in DNA replication would affect many generations of cells
Absolutely they are affected. Infinitely many strands. Many variables go into how severe the birth defects will be.
DNA replication occurs once during mitosis. Replication also occurs once during meiosis even though there are 2 divisions that happen.
The DNA double helix contains two coiled biopolymer strands. The double helix was discovered by James Watson and Francis Crick.
2 strands in total I believe.
how many rounds of chromosome replication occur i the cell pirior to mitosis
Wire made of many strands is 'cable'
DNA is made of 2 strands so when it replicates the strands separate and 2 new strands complete the old strands. leaving 4 strands making 2 sets of DNA, both sets of DNA consist of one old strand and one new strand.- Sierra A. Buchanan
