Correct!

Chromosomes are inside every cell in your body.

Inside each human cell there are 46 chromosomes (23 from mom, and 23 from dad). The chromosomes carry the cell's instructions—telling the cell what to do. The billions of cells in your body carry out their instructions and make you...you.

Sorry, that is incorrect.

Correct!

Your DNA is almost exactly like the DNA in all other human beings.

All humans share 99.9% identical DNA. We are all members of the same species. And, it is our many similarities that make us human, and make our bodies work in much the same way as one another. Just a relatively few genetic differences account for the millions of differences you see in people around you.

The answer is 20,000 - 25,000.

Scientists don't know the exact number of genes for sure, but their best guess is that people have between 20,000 and 25,000. What's funny is that some very simple creatures have about as many genes as people do-like a kind of worm, called "C. elegans," which has about 19,500 genes.

DNA stands for: Deoxyribonucleic Acid

Inside each cell is "deoxyribonucleic acid," or DNA. DNA is like an instruction warehouse telling the cell what its job is inside the body, and what to do to accomplish its job.
