Answer:
1. A locatable region of genomic sequence, corresponding to a unit of inheritance which is associated with regulatory regions, transcribed regions, and/or other functional sequence regions.
2. Were historically defined as the unit of hereditary material that causes a phenotype.
3. May be composed of a union of genomic sequences encoding a coherent set of potentially overlapping functional products.
Explanation:
A gene is a sequence of nucleotide present on a chromosome which determines a trait of an organism. The gene term was provided by the Wilhelm Johannsen in 1909 to refer to the hereditary unit of the organisms.
The genes in eukaryotes are not necessary that they will code for the protein as there are some RNA molecules which are not translated into the protein like rRNA and tRNA molecules.
The sequence of a gene in eukaryotes is a union of the regulatory of the functional and transcribed genes.
Thus, the selected option is correct.
