Top NEET Biology Questions
- Name the class of enzyme that usually catalyzes the following reaction: \[ S - G + S^{\prime} \rightarrow S + S^{\prime} - G \] Where \( G \) represents a group other than hydrogen, \( S \) is a substrate, and \( S^{\prime} \) is another substrate.
- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025

Nomenclature and Taxonomy
A branch of science that deals with the nomenclature, identification, and classification of living organisms and extinct organisms is known as taxonomy. We have millions of species on Earth that are commonly known by their local names.
The nomenclature of an organism is only possible when we correctly know all the specifications of the organism that describes them clearly. The described process of an organism is known as identification.
Rules for the Binomial Taxonomy Nomenclature:
- Irrespective of their origin, these biological names are derived from Latin words and are written in italics.
- ‘Genus’ - is the first word in the biological name whereas the second word represents a specific epithet.
- To show the Latin origin both the genus and specific epithet are separately underlined or written in italics.
- With capital letters, the genus should start and with a small letter, a specific epithet starts.
- The name of the author should be written in the abbreviated form after the specific epithet which denotes the name of the person who described the species such as Mangifera indica Linn. In this Linn indicates the Biologist Linnaeus who for the very first time described the species of mango.
