Which is the final product of the gene?

The final product of a gene is typically a functional protein, which is synthesized through the processes of transcription and translation. During transcription, the gene's DNA sequence is converted into messenger RNA (mRNA). This mRNA is then translated into a specific amino acid sequence, forming a protein that performs various functions in the cell, such as catalyzing biochemical reactions, providing structural support, or regulating biological processes. In some cases, genes can also code for functional RNA molecules, such as ribosomal RNA (rRNA) and transfer RNA (tRNA), which play essential roles in protein synthesis.
