The characteristic feature of the semi-conservative replication of DNA is formation of the leading strand and the lagging strand. DNA polymerases are the enzymes that can add nucleotides to the 3 ' end of the DNA strand only. A DNA double helix is anti-parallel in which one strand runs from 5 ' to 3 ' and the other from 3 ' to 5 ' direction. On the strand having a primer with a 3 ' end, the synthesis of DNA is continuous and forms the leading strand. On the other strand, DNA fragments called Okazaki fragments are produced with multiple RNA primers. It is called the lagging strand. The enzyme DNA ligase joins these Okazaki fragments on the lagging strand. Thus, any defect in the enzyme will affect the lagging strand only and not the leading strand as it does not have any Okazaki fragments.

Paleoclimatologists are the people that study the ancient climate before the availability of the instrumental records or the data and therefore depend on the coral reefs or the rocks and also compare the current climate how dramatically different climate states occur in few decades.
Dina should examine newspaper articles to find out what type of climate was before and now in her hometown and she should also check records of farmer's harvest yield to get what type of weather and climate was there.
