Given the following sequence 5’ – TGT – 3’, the notation 3’ refers to what, specifically?

a.A free hydroxyl group on deoxyribose at position 3 on the ring

b.A free hydroxyl group on thymine at position 3 on the ring

c.A free phosphate group on deoxyribose at position 3 on the ring

d.A free phosphate group on thymine at position 3 on the ring

e.Position 3 of thymine is attached to the sugar of the nucleotide

Respond to each sentance with true or false regarding the replication of DNA:

Complementary base pairing relies on the number of hydrogen bonds that each base can make.

In a single nucleotide, the phosphate group is attached to the 5' carbon of the sugar unit.

The antiparallel arrangement of double-stranded DNA is due to the phosphate group being bonded to the 3' carbon on one strand and the 5' carbon on the complementary strand.

The phosphate attached to the 5' carbon of a given nucleotide links to the 3' -OH of the adjacent nucleotide.

The -OH group on the 3' carbon of the sugar unit is the attachment site for the nitrogenous base.

Hydrofluoric acid, HF (aq), cannot be stored in glass bottles because compounds called silicates in the glass are attacked by the HF(aq). Sodium silicate Na2SiO3, for example, reacts as follows:

Na2SiO3(s) + 8 HF (aq) → H2SiF6(aq) + 2 NaF(aq) + 3 H2O(ɭ) 

(a) How many moles of HF are needed to react with 0.300 mol of Na2SiO3?

(b) How many grams of NaF form when 0.500 mol of HF reacts with excess Na2SiO3?

(c) How many grams of Na2SiO3 can react with 0.800 g of HF?
