Questions…
- How many pairs of chromosomes does a human have?
- What is a zygote?
- One of the videos refers to mitochondrial DNA. This is DNA not found in the nucleus but in the mitochondria. What do mitochondria do in the cell?
- What are the two chromosomes called that determine your sex?
- What is the difference between mitosis & meiosis (apart from the spelling!) [Hint: they both mean ‘cells dividing’]
