Answer:
The correct answer for the fill in the blank is - A sequence of bases on the DNA that codes for a trait.
Gene is described as a segment of DNA ( deoxyribonucleic acid) that codes for a particular protein, which in turn corresponds to a trait/ characteristic of the living organism.
Gene is first transcribed into mRNA ( messenger RNA) through a process called transcription. mRNA is then converted into protein through a process called translation.
The protein thus formed corresponds to a particular trait ( like eye color, hair color).
