Cell
Basic/Smallest unit of life.
Nucleus
Largest organelle in a cell, directs activities, contains DNA acts like the brain of the cell
DNA
Deoxyribonucleic acid, organism's genetic instructions

Gene
Sections of DNA (specific segment of DNA) that code for specific traits
Where the cell, nucleus, and chromosomes are located.
Inside the cell the largest organelle, the nucleus, can be found, and inside the nucleus are chromosomes.
How many chromosomes do humans have
46 chromosomes or 23 pairs
Chromosomes, genes and DNA are located
in the Nucleus
Half of these come from one parent and half come from the other parent.
Chromosomes

eye color/ hair texture/ face shape
