All the molecules generated during PCR will not be full length. Some will also be of intermediate length. Which of the statements is correct?

#Unit 13. Methods in Biology
  1. After first cycle, majority of the molecules will be full length and only some will be of intermediate length
  2. In the next cycle, each intermediate molecule will generate one intermediate molecule and one target molecule
  3. The number of full length molecules increase as number of cycles proceed
  4. The number of intermediate molecules increase geometrically and the number of target molecules increase arithmetically
