Explanation:
Mitochondria is an organelle present in a eukaryotic cell that performs the function of producing ATP molecules from the available substrates in the cell.
The mitochondria organelle has its DNA other than the cellular DNA which shows that it was once an independent organism. This was proved by the endosymbiotic theory that during the formation of the eukaryote cell, the proto-eukaryote engulfed the chemosynthetic bacteria which later formed the symbiotic relationship with the cell and evolved into the mitochondria.
Thus, Option-A is the correct answer.
Answer: The sugar in DNA is called a deoxyribose because it doesn't have a hydroxyl group at the 2' position. Instead it just has a hydrogen
Explanation:
Answer: A
Explanation:
During the test that lead to the discovery of okazaki fragments on the lagging strand, a strand which is discontinuously synthesized with small DNA molecules to its own Primer RNA and was called okazaki fragments. The synthesis along the lagging strand is in 5' to 3' direction. As it moves, the primase synthesizes short RNA primer, to which the DNA nucleotides are added by DNA polymerase.
It was discovered that DNA synthesis is always in the 5' to 3'direction in both strands.
DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication
