WebOct 13, 2015 · It needs primers to start it's work. Binding of molecules happen by chance, so the more there are of your primer, the more likely it is that it would bind to any given string of complementary DNA. DNA replication occurs in the five prime to three prime direction because phosphate doesn't allow the reverse reaction. WebThree different approaches can be used for priming cDNA reactions in two-step assays: oligo(dT) primers, random primers, or sequence specific primers (Figure 2, Table 2). Often, a mixture of oligo(dT)s and random …

WebWhen DNA is being copied, one of the two new strands of DNA at a replication fork is made continuously and is called the leading strand. The other strand is produced in many small pieces called Okazaki fragments, each of which begins with its own RNA primer, and is known as the lagging strand.
