Ans. (C). two double-stranded dna molecules, each composed of one new and one old strand.
DNA replication can be defined as a process that involves formation of two DNA replica molecules (exact copies) from one parent DNA molecule.The double-stranded parent DNA molecule gets separated and provides two template DNA strands for daughter strands synthesis.
Enzyme DNA polymerase adds nucleotides complementary to template strands and synthesize daughter strands. Hence, two double-stranded DNA molecules are formed, each having one old and one new strand.
The correct answer is option A which is in prokaryotes photosynthesis takes place on the folds and in eukorytes, it is present in specialized organelles.
<h3>Explanation:</h3>
Prokaryotic cells don't have distant nucleus and specialized organelles. in photosynthesizing prokaryotes, Photosynthesis takes place on the system of folded membranes near the cell membrane known as mesosomes.
While eukaryotes, all organelles are fully specialized and chloroplasts are double membrane organelle for photosynthesis.
