Answer: The correct answer is- B) Okazaki fragments are made on the lagging strand but not on the leading strand.
DNA replication is a biological process in which two identical replica of DNA are produced from single original DNA molecule through an enzyme called DNA polymerase.
The strands of double helical DNA are first separated ( with the help of helicase enzyme) so that the template DNA strands are exposed. DNA is synthesised in 5' to 3' direction.
Leading strand ( whose template strand is 3' to 5') is synthesized in continuous manner as DNA polymerase moves along the direction of replication folk.
Whereas lagging strand ( whose template strand is 5' to 3') is synthesized in a discontinuous manner as it requires multiple primers to synthesise the DNA. It generates small fragments of DNA called okazaki fragments.
Is a fallacy that consists of a false appeal to the authority of "everyone"; based on the assumption that a course of action should be taken or an idea should be supported because "everyone" is doing it or believes it.
There are two types of succession that lead to the increasment of the ecosystem:
1. Primary succession is the change in the structure of an ecosystem represented with the increase of the ecological community on an area that has not been previously occupied by an ecological community such as area after the lava flow or glacial lake. The first organisms of primary succession are pioneer plants usually, lichens and mosses.
2. Secondary succession includes the step of removal of pre-existing community and after that, colonization of the new one.
