Question

Answer 1

Answer #1

29. Option d is correct. Endospores allow a cell to survive environmental change.

30. Option c is correct. The enzyme in step 1 is RNA polymerase. The step shows transcription which is the conversion of DNA into RNA.

31. Option c is correct. The enzyme in step 2 is reverse transcriptase. It helps in the formation of cDNA from rna.

32. Proof that a microbe could cause a disease was provided by Koch. These are known as Koch's postulates.
