Sample Flashcards
What is a gene?
A section of DNA that codes for the production of a specific protein. The sequence of bases in the gene determines which protein is made.
What is an allele?
A different version of the same gene. For example, the gene for eye colour has alleles for brown eyes and blue eyes. Alleles arise due to mutations in the original gene.
