On Monday's homework, we made a concept map onDNA, genes, protien, m-RNA/t-RNA, codons,amino acid,and chromosomes. This is important because it helps us understand these things and also know what they do together. For example, the DNA exposes the gene which forms the m-RNA and so on.
On Tuesday we learned about reproduction. We learned that cells come from other cells. They replicate the DNA. They are exactly the same. This is called A-sexual. This means that you could reproduce by it self. Sexual is when you have to have contact with another cell or person to reproduce. This is important because your body is constantly reproducing new cells. We also learned about chromosomes. The boy has an x and y chromosome, and the girl has a x and x chromosomes. If the baby gets two x chromosomes, then it is a girl. If they have an x and y chromosome, then it is a boy. The males have a sperm cell, and the girl have an ova cell. When combined, they make a new cell. That is called fertilization. This is important because it shows how people are reproduced. We also did this on Wednesday.
On Thursday and Friday, We did a lab on looking through a microscope looking at the ends of an onions root. This is because the roots grow to get more water. We saw cells and the DNA. Then we answered questions on it.
