Final Answer :
A
Explanation :
The modern definition of a gene encompasses a DNA sequence that encodes a specific RNA or protein product, reflecting our understanding that genes can encode both proteins and various forms of RNA (e.g., mRNA, tRNA, rRNA, miRNA) that may not necessarily be translated into proteins.
