What is a gene?
The term "gene" can be interpreted in a number of ways. The molecular gene is a sequence of nucleotides in DNA that is transcribed to form a functional RNA, whereas the Mendelian gene is the fundamental unit of inheritance. Protein-coding genes and noncoding genes are the two categories of molecular genes.
Gene is basically responsible for the inheritance of a particular character, the character expressed in an individual with the help of the protein responsible for that particular character. DNA has a nucleotide sequence in which collectively triplets are called codon which is mainly responsible for the protein-coding.
Hence, a gene ( codon in the form of a triplet ) that codes a specific protein.
