Answer:
A molecule of DNA is made up of two strands which are joined by the hydrogen bonds present in the nucleotide bases. The sugar and phosphate make up the backbone of the DNA. The sequence of the nucleotide bases determines the traits that an organism will carry. Genes are hereditary molecules which are made up of sections of DNA. Together, they make up the entire genome for the organism. Each gene is located on a specific place inside the chromosomes. The chromosomes are the element of reproduction as they undergo the process of meiosis and duplicate themselves.

Answer:
The study reported here presents a comparative screening of three medicinal plants including oregano (Origanum vulgare L.), lavender (Lavandula angustifolia) and lemon balm (Melissa officinalis) having the same geographical origin, the Southeast region of Romania, and growing in the same natural conditions. The contents of total phenolics and total flavonoids for the extracts of these were determined. Furthermore, the total antioxidant capacity was also evaluated. It was found that Origanum vulgare and Melissa officinalis extracts present the most effective antioxidant capacity in scavenging DPPH radicals, while Lavandula angustifolia is less active. High performance liquid chromatography-mass spectrometry analysis was used to identify the components of extracts. Major phenolic acids identified in the analysed species were ferulic, rosmarinic, p-coumaric and caffeic, while predominant flavonoids were quercetin, apigenin kaempherol, which were present as glucosides.
