Question

What is true about the relationship of DNA and genes? Segments of DNA contain the code to make a gene. Each DNA molecule makes up a segment of a gene. Segments of genes contain the code to make DNA. Each gene contains a segment of a DNA molecule.

Answer 1

DNA is made out of two long, twisted strands that contain complementary genetic information (like a picture and its negative). A gene is a segment of DNA that is passed down from parents to children and confers a trait to the offspring. Genes are organized and packaged in units called “chromosomes.”
