Chapter 8 Lesson 3

Question 1

What is the definition of transcription?

Answer 1

The process of making RNA by copying

Question 2

What is the central dogma?

Answer 2

The process of DNA transcribing into RNA, and then later given a specific trait

Question 3

What bases in RNA pair?

Answer 3

C -> G
A -> U

Question 4

What are some similarities between DNA and RNA?

Answer 4

They both contain sugar, phosphorous, and a nitrogenous base

Question 5

What are some differences between DNA and RNA?

Answer 5

DNA contains a deoxyribose sugar while RNA contains a ribose sugar

Question 6

What are the parts of a Eukaryotic gene?

Answer 6

• Enhancer/Silencer
• Promoter
• Exons
• Introns

Question 7

What are the stages of transcription?

Answer 7

1. Initiation
2. Elongation
3. Termination

Question 8

Describe the initiation stage?

Answer 8

Transcription factors are being added and binded to promoters and RNA polymerase gets added and they begin the copying process

Question 9

Describe the elongation stage?

Answer 9

RNA polymerase breaks freeze and adds a 5’ protective cap. As RNA polymerase copies, it begins to splice out the introns

Question 10

Describe the termination stage?

Answer 10

At the polysyndeton site, the termination sequence is recognized and cut. A poly A tail is added to the end of an RNA molecule. The longer the tail = a longer time spent in the cytoplasm = more protiens being made
