Lec 7-1

Question 1

Gene transcription is going from

Answer 1

DNA to RNA

Question 2

RNA vs DNA differences

Answer 2

RNA contains a ribose sugar rather than a deoxyribose sugar

2’ carbon of sugar has a hydroxyl group in RNA which makes it more unstable

Question 3

RNA can take on

Answer 3

Many secondary structures (ie hairpin)

Question 4

RNA can act like

Answer 4

Proteins

Flexible secondary shape allow some RNA to act as ribozymes

Question 5

Ribozymes

Answer 5

Cut/edit out own sequence

Connect RNA molecules together

Replicate other RNA

Catalyze peptide bonds formation between amino acids

Question 6

Theory of RNA

Answer 6

RNA was the original genetic material on the planet 4 billion years ago (Only RNA and ribozymes)

Question 7

Transcription requires 3 major components

Answer 7

A DNA template

Raw materials needed to build a new RNA molecule

The transcription apparatus, consisting of the proteins necessary for catalyzing the synthesis of RNA

Question 8

Raw materials needed to build a new RNA molecule

Answer 8

ribonucleotide triphosphates- rNTPs
