This week in science

This week in science class we discussed reproduction and DNA. We learned that cells come from other cells. The cells split. Most of them are asexual. This means that it doesn't need another cell for reproduction. There is an egg cell which comes from females and a sperm cell that comes from males. These cells must combine to make a new type of cell. No cells are exactly the same. You look different from your parents because it is coming from two different organisms. Some words for this are DNA, gene, protein, chromosome, mRNA and codon.
