The basic reason why unripe fruits have defensive chemicals is that they need to protect the seeds that are not ready to germinate. On the other hand, the seeds of the ripe fruits are ready to germinate and so they need to get spread with the help of animals and birds and so there are no defensive chemicals. These seeds spread to different places and the soils help them to germinate under suitable conditions.

Answer:
- Pol III binds to 3' end of primer B
- Poll III moves to 5' to 3',adding DNA nucleotides to primer B
- Pol I binds to 5' end primer A
- Pol I replaces primer A with DNA
- DNA ligase links fragments A and B
Explanation:
Both strands of parental DNA acts as a template for the synthesis of new DNA. The site of synthesis is called replication fork because the daughter strands look similar to <em>two-pronged fork.</em> The strands formed from Okazaki fragments(short sequences of DNA nucleotides) is called the <u>lagging strands,</u> which is synthesized in short fragments and in the opposite direction. While the strand that is synthesized continuously and in the same direction as the movement of the replication fork is called the <u>leading strand.</u> Both strands are synthesized in a 5'→3' direction. DNA ligase join these fragments together.
The mutation in the sperm cell could be passed on to offspring, while the skin cell mutation could only affect the individual.
