        I think that the author does not like Santa Claus or he thinks that Santa Claus is obese and imaginary. In the whole article he says that Santa Claus is a made up person. He says that in different ways, in scientific  matters. He says that it is not possible that there is a real person like that, and he backs the information with a lot of the exact information. One thing he says is about that amount of kids, and how many are Christian. He also talks about how there is about 3.5 kids in every household, but that is just averaging some people have more kids while others  people have no kids at all. Isn't is interesting how he says it all. He also talks about how many houses he gets done in 24 hours right, but since there are different time zones in all the different places wouldn't he possibly get done??
       Not only does he talk about the time and the amount of kids, but he also writes about the amount of cookies and milk that Santa would eat. He says the amount of calories that they are each worth, but does that necessarily mean he eats all the cookies or that everybody leaves him a cookie. What if he only eats how much he is able to , then he puts them in a bag and collects them all. Another thing he mentions is the weight of the sleigh and the over-weight man that is in it. I think that it is possible to carry a big amount of toys in 2 different sleighs, isn't is possible that Santa has people that help him? Well if it is  doesn't  is that possible.

DNA Replication

       DNA always duplicates, so that when your cells divide they will all contain the exact same DNA. The DNA first splits from the middle. When it is splitting new nucleotides are forming  on the other side or strand of the DNA. This is happening to both sides. So while it is splitting from the middle it is  slowly forming two DNAs from just one. So this progress will keep going until those new nucleotides stick to one of the old ones and then they will become two complete exact DNAs. One strand is made up of all the old nucleotides, and there will be another strand in which all the new nucleotides will be. So now there are two DNAs that each have one strand with the original DNA and another with the new strand of nucleotide.
       This will keep happening all the time that there will be new DNA forming. So this is how DNA is replicated. This usually just needs to start when the DNA is copied during the interphase in a cell's replication to make two daughter cells. All this means that when you were one cell big, there was just one piece of DNA in you so that first DNA is the actual original of all your other DNA.

      DNA is the part of us that gives us each different characteristics. Its structure was very complex, and it took many people to contribute to its finding. The DNA in our body looks like a twisted ladder. It has many pieces to it for example it is made up of groups. On the edge of the   DNA there are deoxyribose sugar and of phospategroups. DNA also has base groups a, t, c, and g. They stand for adenine, thymine, cytosine, and guanine. These bases are designed to fit together. So adenine and thymine go together and guanine and cytosine go together.These are called base groups  .
     In class we have been building models of the DNA.
