A gene is best defined as a sequence of nucleotides in DNA that codes for a functional product.

Here's why:

1. A gene is indeed a segment of DNA, but this definition is too broad. DNA also contains non-coding regions, so not every segment of DNA is a gene.

2. Three nucleotides that code for an amino acid is known as a codon, not a gene.

3. A sequence of nucleotides in RNA that codes for a functional product is known as mRNA (messenger RNA), which is a product of gene transcription but not a gene itself.

4. A transcribed unit of DNA refers to the process where a particular segment of DNA is copied into RNA (mRNA) by the enzyme RNA polymerase. This process is part of gene expression, but it does not define what a gene is.

Therefore, the best definition of a gene is a sequence of nucleotides in DNA that codes for a functional product. This functional product is usually a protein, but it can also be an RNA molecule in some cases.
