Chromosomes are actually made up of genes put together like beads on a string. Human body cells have about 35,000 genes each! Each gene will control a trait. One chromosome in a pair is from the female, the other is from the male. Usually, there are two copies of every gene. They are lined up in the same order for both chromosomes. The alleles on the genes may be different, but A will line up with any A, capital or lowercase, and B will always line up with any B and so on. Sort of like if you were making 2 identical bracelets. If you were making 2 identical bracelets, then you would want red to match red, and blue to match blue. Even if you had 2 beads that are different sizes, you might line them up red on red and blue on blue; unless you are a perfectionist. Chromosome alignment is very important because if the chromosomes don't align, mutations could occur in the DNA. Some mutations are good, but most do not end well.
Why is this important to me??
This was one of the more memorable topics for me. This was the topic I remembered the best because it was an interesting topic and it was the last topic we talked about that had to do with cells, and it was the last BIG test we had. We are also studying human growth and reproduction so my memory is always being refreshed.
To demonstrate your learning, here is a kahoot for you to test your knowledge.
