Explanation: I just took the quiz
PEA stands for Phenylethyl Alcohol Agar medium. It is a selective solid medium that is used to culture Gram Positive bacteria. In this medium, phenylethyl alcohol is an active ingredient that inhibits the growth of Gram Negative bacteria. It causes leakage in the cell membrane of Gram Negative bacteria. It is also used for the growth of obligate anaerobic bacteria.

Answer:
The correct answer is- lagging strand
Explanation:
During the DNA replication both the strands acts as template strand and DNA polymerase replicated both the strand. During this replication, one strand is replicated continuously which is called the leading strand and another strand is not synthesized in a continuous manner.
So small DNA fragments are formed due to discontinuous replication of DNA which is called Okazaki fragments. These fragments are then joined by DNA ligase and the strand is called lagging strand.
Therefore the strand which is synthesized in a discontinuous manner is called lagging strand.
