Flashcards
What are genes?
What are genes?
Segments of DNA that instruct the cell to produce specific proteins, determining heredity.
What is DNA's role in a cell?
What is DNA's role in a cell?
A complex molecule containing the genetic information that determines the characteristics of living things; it directs the cell's activities by instructing which proteins to make.
What are chromosomes?
What are chromosomes?
Structures within a cell's nucleus that are made of DNA and protein; they contain the genetic information in the form of genes.
