Question

Based on these cell models, which of

the following observations about DNA is
correct?
DNA is not found in cells.
DNA is larger than cells.
DNA is smaller than cells.
DNA is found outside the cell.

Answer 1

DNA is smaller than cells.

Which is bigger, DNA or a gene?

DNA stands for deoxyribonucleic acid. It is the chemical name of the molecule making up our genes. One entire DNA molecule is called a chromosome. A normal human cell has 46 chromosomes, therefore 46 DNA molecules. We have 46 DNA molecules, but thousands of genes. Therefore, every chromosome contains many, many genes.

Think of it this way: one chromosome (one DNA molecule) is like a book and one gene is one page in the book.
