Web16 jul. 2016 · 3. DNA replication likes one direction. Not the boy band, but rather it prefers to replicate in a certain direction over the other. Publishing their findings in Science Advances, scientists have discovered an enzyme that can perform the procedure in the opposite direction and characterized how it works - a complex process. WebHowever, DNA polymerase enzymes are only able to synthesize DNA in the 5′ 3′ direction. This means that one strand of the parent double helix, called the leading strand, can be copied out in a continuous manner, but replication of the lagging strand has to be carried out in a discontinuous fashion, resulting in a series of short segments that must be ligated … how many children did kobe bryant have https://trabzontelcit.com
