Living organisms use solely RNA primers, while laboratory techniques in biochemistry and molecular biology that require in vitro DNA synthesis (such as D…
11:45 However, DNA and RNA can still be complementary to one another even though they may have different nucleotides.
Such fragments are too long to be sequenced in a single sequence read using the chain termination method. The lagging strand is that strand of the DNA double helix that is orientated in a 5' to 3' manner.
Primers were once a standard part of every child's education. primer therefore serves to prime and lay a foundation for DNA synthesis.
