NEET PG DENTAL EXAM

Detailed explanation-1: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria (Figure 5) are structures within cells that convert the energy from food into a form that cells can use.

Detailed explanation-2: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center. DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.

Detailed explanation-3: -The majority of the cell’s DNA is present in the nucleus of the eukaryotic cell and it is called nuclear DNA. A small amount of DNA is also present in the mitochondria. In plants, DNA is also present in the chloroplast. In prokaryotic cells, DNA is present in the nucleoid region in the cytoplasm.

Detailed explanation-4: -Both DNA and RNA are present inside the double membrane-bound organelle called the nucleus of the cell. The nucleus usually lies at the center of the cell.
