Spletpred toliko dnevi: 2 · DNA replication refers to the process of creating a new strand of DNA from existing nucleotides (the building blocks of DNA). This process is essential for cell division, growth, and repair, as well as for the transmission of genetic information from one generation to the next. SpletDNA primase forms an RNA primer, and DNA polymerase extends the DNA strand from the RNA primer. DNA synthesis occurs only in the 5' to 3' direction. On the leading strand, … jeep statistics
