| Definition | DNA is a long polymer with a phosphate and deoxyribose backbone. It has four different bases: cytosine, thymine, adenine, and guanine. | RNA is a polymer with a phosphate and ribose backbone with four different bases: cytosine, uracil, adenine, and guanine. |
| Location | DNA is found in the nucleus of a cell and in mitochondria. | RNA is found in nucleus, cytoplasm, and in the ribosome. |
| Sugar portion | 2-deoxyribose | Ribose |

Vernalization : It is the treatment of low temperature for reducing vegetative phase and hastening the reproductive phase. It was first discovered by Lysenko.
Vernalisation refers specially to the promotion of flowering by a period of low temperature. For example - Subjecting the growing of a biennial plant to a cold treatment stimulates a subsequent photoperiodic flowering response.

Cytokinesis involves the division of the cytoplasm. The cytoplasmic division in the animal cell takes place by furrow formation while in plant cell it occurs by phragmoplast formation. It mainly takes place at the end of anaphase. The formation of cell plate completely separates the two daughter cells at the telophase.

The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water. The electron transport chain is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons across a membrane. The electron transport chain is built up of peptides, enzymes, and other molecules.

Unicellular algae are plant-like autotrophs and contain chlorophyll. They include groups that have both multicellular and unicellular species:
Euglenophyta, flagellated, mostly unicellular algae that occur often in freshwater. In contrast to most other algae, they lack cell walls and can be mixotrophic (both autotrophic and heterotrophic). An example is Euglena gracilis.
Chlorophyta (green algae), mostly unicellular algae found in fresh water. The chlorophyta are of particular importance because they are believed to be most closely related to the evolution of land plants.
Diatoms, unicellular algae that have siliceous cell walls. They are the most abundant form of algae in the ocean, although they can be found in fresh water as well. They account for about 40% of the world's primary marine production, and produce about 25% of the world's oxygen. Diatoms are very diverse, and comprise about 100,000 species.
Dinoflagellates, unicellular flagellated algae, with some that are armored with cellulose.[48] Dinoflagellates can be mixotrophic, and are the algae responsible for red tide. Some dinoflagellates, like Pyrocystis fusiformis, are capable of bioluminescence.

If the substrate concentration increases, initially the velocity of enzymatic reaction rises. In the final stage, the reaction reaches a maximum velocity or V max. This velocity does not rise any further even if there is an increase in substrate concentration. The reason is that at V max, there are no free enzyme molecules available that can bind with extra substrate molecules.

| GLYCOGENOLYSIS | GLUCONEOGENESIS |
| It results in the formation of glucose by breaking down glycogen molecules stored in the liver. | It results in the formation of glucose molecules from non-carbohydrate sources. |
| Glycogen is broken down to form Glucose- 6-phosphate. | Amino acids, lactic acids are converted into glucose. |
| It is hydrolytic process. | It is anabolic process. |
| Less amount of ATP is consumed. | 6 molecules of ATP are consumed per 1 glucose molecule synthesised. |

Diabetes mellitus occurs due to insulin resistance or insulin deficiency and subsequent high blood glucose levels. Diabetes Insipidus on the other hand develops as a result of the stilted production of a hormone in the brain, which is released to stop the kidneys producing so much urine in order to retain water. In diabetes mellitus, hyperglycemia is usually caused by low insulin levels (Diabetes mellitus type 1) and/or by resistance to insulin at the cellular level (Diabetes mellitus type 2), depending on the type and state of the disease. Hypoglycemia is different from hyperglycemia, which occurs when you have too much sugar in your bloodstream. Hypoglycemia can happen in people with diabetes if the body produces too much insulin. Insulin is a hormone that breaks down sugar so that you can use it for energy.
