Question

I'm having a hard time with my exam. I would love some help. they are multiple choice.

An can synthesize DNA from an RNA template; enzyme found in retroviruses 12. enzyme that Questions 13-50, each multiple choice question has one correct answer. 13. In bacteria, which of the following helps guide RNA polymerase to the -10 and -35 box of the promoter? a. regulator b. basal transcription factor c. inducer d. sigma factor e. TATA director Listed below are the events of transcription initiation in a typical bacterial cell, but they order. Use this information to answer question 14. are out of chronological i. Sigma binds to the promoter region. ii. The double helix of DNA is unwound, breaking hydrogen bonds between complementary strands. iii. Sigma binds to RNA polymerase. iv. Sigma is released. a. ii, ii, iv, i b. ii, ii, i, iv

Explanation / Answer

13. It is the sigma factor that are that binds with the RNA polymerase and help in recognizing promoter sequences that are located at -10 and -35 . Hence,option d is correct.

14. First sigma factors binds with RNA polymerase , then RNA polymease along with sigma factor recognize the promoter sequence. Afterwards, DNA whose transcription has to perform, will unwind with the help of RNA polymease and afterwards sigma factor released. Hence, option c is correct.
