Question

2.5 points Save Answer Discontinuous replication refers to the fact that: O A DNA synthesis begins at multiple origins of replication OB. one of the daughter strands of a replicated piece of DNA is made in short fragments that are joined together OC DNA synthesis is not continuous with RNA synthesis OD. DNA synthesis starts and stops many times before completion

Answer 1

Answer in 'B' i.e. one of the daughter strands of a replicated piece of DNA is made in Short fragments that joined together are Explanation in where are DNA always OY DNA replication is a process the exact copies of DNA created. The replication Occur on the basis of template DNA previously Synthesized DNA. In this process the previously Synthesized Unzip and Strand act as a template. the basis of template to strand is Synthesized which are Leading strand - continuous Strand- discontinuous DNA each two O ชา - ④ Lagging strand Strand 1000 - 2000 Discontinuous replication or logging Synthesis; Logging Strand is Synthesized on 5'-3' of template DNA in short of segments nucleotides in 5'-3' direction. These segments are called Okazaki frogments. Synthesis of each Okazaki fragments begins with RNA primer by primase and is carried out by polymerase-III · » Synthesized

Thus synthesis of lagging strand of DNA is discontinuous and needs a series of RNA primers for each okazaki fragments.

motion of fork Replication fork 5 RNA Primer leading strand 5 OOC 51 Okazaki fragments Lagging Strand fig: Leading and Lagging strand synthesis. so the answer is B.
