WebDNA replication is semi-conservative. This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).

WebAug 17, 2024 · Features of Eukaryotic DNA Replication. Replication is bi-directional and originates at multiple origins of replication (Ori C) in eukaryotes. DNA replication uses a semi-conservative method that results in a double-stranded DNA with one parental strand and a new daughter strand. It occurs only in the S phase and at many chromosomal origins.

Nitrogen is a major constituent of DNA. N is by far the most abundant isotope of nitrogen, but DNA with the heavier (but non-radioactive) N isotope is also functional.
