Question

QUESTION 1 bonds are responsible for linking together adjacent nucleotides a single strand of DNA. in O peptide O phosphodiester O noncovalent O hydrogen QUESTION 2 Each deoxyribonucleotide is composed of a O ribose, nitrogenous base, and a sugar. O ribose, nitrogenous base, and a phosphate group. o deoxy ribose, nitrogenous base, and a phosphate group O deoxy ribose, hydrogen bond, and a phosphate group. QUESTION 3 bonds are responsible for holding together complementary nitrogenous bases in double stranded DNA Peptide Phosphodiester

Explanation / Answer

3.

Complenentary nitrogenous bases in double stranded DNA are held together by Hydrogen bonds where Adenine forms hydrogen bonds with Thymine and Cystosine can forms hydrogen bonds with Guanine.

4.

According to Chargaff's rule ,

[A]+[T] = [G] + [C]

[A]+[T]+[G]+[C] = 100%

Since Adenine is paired to Thymine

[A] = [T]

Again Cystosine is paired to Guanine

[C] = [G]

Since

[C] = 10% therefore [G]=10%

Now,

[A] + [T] + 20% = 100%

2[A] = 80% ( Since [A] = [T])

[A] = 40%

Hence answer is 40%
