The second option is the right one.
For DNA replication to occur, an existing double-stranded DNA (dsDNA) must be “unzipped” to form two strands of single-stranded DNA (ssDNA). The ssDNA then serves as the scaffold onto which a complementary strand of DNA is built by adding nucleotides one by one. At the end of this process, there are two identical strands of dsDNA, which then move into the daughter cells.
Answer:
The correct answers are:
1. A. eukaryote 2. B prokaryote 3. A. animals 4. B bacteria
Explanation:
The cell illustrated in A is a eukaryotic cell as it has a membrane-bound nucleus and organelles. The nucleus contains chromatin in the denser area in the center of the nucleus called the nucleolus. An example of this type of cell is animals or plants.
The other cell is a prokaryotic cell as it has no cell organelle or true nucleus. It has a denser area in cell plasm called nucleoid that has chromosome present. The example of these cells are bacteria or archeae.
