WebbIn DNA, each nucleotide is made up of three parts: a 5-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base. DNA uses four kinds of nitrogenous bases: … WebbAdenine pairs with thymine, thymine with adenine, cytosine with guanine and guanine with cytosine. A primer is needed to start replication. Leading strand is synthesised continuously. DNA...

(a principal polymerase in DNA replication) but that DNA polymerase β (a principal polymerase in DNA repair processes) does not play a significant role in this system. WebbReplication factor A (RF-A) is a heterotrimeric single-stranded-DNA-binding protein which is conserved in all eukaryotes. Since the availability of conditional mutants is an essential step to define functions and interactions of RF-A in vivo, we have produced and characterized mutations in the RFA1 gene, encoding the p70 subunit of the complex in … tacografo jatai
