Answer:
Apples : adenine
Trees : thymine
Cars : cytosine
Garages : guanine
Explanation:
The bases in DNA are adenine, thymine, guanine, and cytosine. It helps to remember the popular mnemonic, "apples in the tree," that helps you remember that A goes with T, and "car in the garage," so C goes with G, to understand how DNA bases pair. The bases in RNA are adenine, uracil, guanine, and cytosine.
Answer:
mtDNA is used, consider forensic laboratories to characterize bone remains and identify individuals who have other evidence
The disadvantage of using mtDNA in relation to nuclear DNA is that it does not identify individuals unambiguously, it only detects relationships between groups of individuals
Answer:
Option B = Lipids
Explanation:
Lipids include waxes, fats, steroids and oils. These are found in both eukaryotes and prokaryotes. Lipids play important role of energy storage, membrane formation, cell division and protection.
Structure of lipids:
Lipids are made up of triglyceride which are further consist of fatty acids and alcohol glycerol. Because of great diversity more than 10,000 lipids are discovered. Lipids are smaller than the protein.
Example:
Fatty acids are the lipids and act as a building blocks for other kind of lipids. The carboxyl group (-COOH) in fatty acids attached to the carbon chain trough attached hydrogen and make the chain water soluble. There are two kinds of fatty acids saturated and unsaturated. The saturated fatty acid has single bonds and unsaturated fatty acids have double bonds. The unsaturated fatty acids yield oils when combine with triglycerides.
Function of lipids:
Lipids play important role in organism. Some are important roles are given below:
1. They make protective barrier.
2. They take part in the formation of cell wall of plants and cell membrane.
3. They are also act as an energy storage device.
4. They take part in the formation of Golgi apparatus, nuclear envelop and other cellular compartments.
5. They provide the insulation against harsh environment to the vital organs
