Dna replication and its types
Websources. The insertion of small RNA segments 10 to 15 nucleotides long is the next step in DNA replication. These sequences, known as RNA primers, are created by an enzyme known as primase (in eukaryotes, the primase is a kind of DNA polymerase known as a [alpha]). Primers initiate the replication process by acting as binding sites for DNA …

WebDNA replicates by a semi-conservative method in which each of the two parental DNA strands act as a template for new DNA to be synthesized. After replication, each DNA has one parental or “old” strand, and one daughter or “new” strand. Errors made during replication are typically repaired. If they are not, mutations can result. WebThere are three types of DNA Mutations: base substitutions, deletions and insertions. 1.
