1. True/False: DNA replication is considered "semi-conservative" because only half of the chromosomes are copied during S phase
BARSIC [14]

Answer:

1) The statement is false

2) Option A) deoxyribose, phosphate, and a nitrogenous base

Explanation:

1) In semi-conservative DNA replication:

- a parent double-stranded DNA splits in two.

- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand

- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.

Thus, because the parent strand is retained in the newly synthesized DNA, DNA replication is described as semi-conservative

2) DNA consists of several repeating units of polydeoxynucleotides where each is made up of a nitrogenous base (Adenine, thymine, cytosine or guanine) linked to

deoxyribose sugar by an N-glycosidic linkage, and then the sugar linked to a phosphate group by phosphoester bond.
