6.3 Genetic information in nucleotide sequence

Question 1

During the synthesis of DNA or RNA, most genetic information is “read” from _______ DNA

Answer 1

unwound

Question 2

In what case is some genetic infromation accessible within double stranded DNA

Answer 2

This is when DNA-binding proteins regulate gene expression

Question 3

What are the 4 chemical factors in which DNA and RNA differ

Answer 3

DNA:
1. Deoxyribose sugar
2. Thymine base
3. usually double stranded
4. self replicating
RNA:
1. Ribose sugar
2. Uracil
3. usually single stranded
4. Cannot self replicate

Question 4

Explain the folding pattern of RNA

Answer 4

Most RNAs are single stranded but can form base pairs within other parts of the same molecule, becuase RNA is flexible
