Question

Press esc to exit full screern True or False about DNA? . Palindromic sequences can potentially form cruciform structures . Deoxyribose is bound to the nitrogenous base at C-1' A pyrimidine in one strand of DNA always hydrogen bonds with a purine in the opposite strand . GC pairs share 3 glycosidic bonds The phosphodiester bonds that link adjacent nucleotides join the 3' hydroxyl of one nucleotide to the 5' hydroxyl of the next . The phosphodiester bonds that link adjacent nucleotides are uncharged under physiological conditions I1 406/420 BIOL301 Lecture 8 Module 5 110xaE

Explanation / Answer

1. True

Palindromic sequences can form cruciform structures due to sequence complementarity.

2. True

A nitrogen base is bonded to C1 of the sugar.

3. True

A purine always pairs with a pyrimidine.

4. False

GC base pair has three hydrogen bonds.

5. False

The phosphodiester bond links 3'-OH group with the 5'-Phosphate group of the next nucleotide.

6. False

The phosphodiester bond is charged under physiological conditions.
