Answer:
The correct answer will be option-C
Explanation:
Replication is a complex process which makes copies or replicates the DNA in every organism present on the Earth. Replication is an ATP dependent process which is catalysed by several enzymes including DNA helicase, polymerase, primase.
During replication, the two strands are synthesized from parent strand in which the strand which is synthesized in 5' to 3' direction is known as the leading strand which is continuous whereas another strand synthesized in 3' to 5' direction is known as lagging strand as it is produced in the lags.
Since in the leading strand DNA polymerase adds nucleotides at 3' end, therefore, it requires only one RNA primer which assists DNA polymerase to proceed the reaction whereas in the lagging strand since the strands are synthesized in the lags so possess many RNA primers so that DNA polymerase can bind.
Thus, option-C is the correct answer.
Answer:
Yes.
Explanation:
Yes, small plants began to grow along the remaining soil because of the presence of seeds in the soil that sense suitable environmental condition and come out of the soil. The ashes of burn trees have huge amount of nutrients in the form of minerals that triggers the growth of small plants. After the destruction of forest, new plants grow on that land, this type of phenomenon is called ecological succession.
Answer: D
Explanation:
When a photon hit photosystem II, light energy absorbed by one of the pigments in photosystem II, energy is carried from one pigment to another and reach down to the reaction center.
Answer - Genetic Engineering (Confidently Correct)
Reason - With Technology we can change the genetics of a species and help it adapt to it env. to survive longer and reproduce.
