Question 1

What are the differences between DNA and RNA?

Answer 1

1. ribose instead of deoxyribose in RNA
2. uracil replaces thymine in RNA, A=U
3. RNA is mostly single stranded (tRNA has small areas that are double stranded)
4. RNA is complementary to a DNA template

Question 2

In genetics, what is a promoter?

Answer 2

a region of DNA that initiates the transcription of a particular gene

Question 3

Where does the promoter bind to begin transcription?

Answer 3

the initiation site

Question 4

What is RNA polymerase responsible for?

Answer 4

producing the primary transcript RNA (RNAP constructs RNA chains using DNA genes as templates, a process called transcription)

Question 5

All RNA molecules begin with the codon ____.

Answer 5

AUG

Question 6

Each codon dictates a specific ____.

Answer 6

amino acid

Question 7
