In which enzyme would a defect majorly affect the formation of a whole new lagging strand without affecting the leading strand?

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.

if you’re on Plato the answer is A) DNA ligase

Hope this helps!

Explanation:

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
