This week in science we learned more about DNA, the size order of cell parts, and how a cell compares to other things.

We learned more about DNA by reading sections of a DNA book and doing some simulations online. One thing I learned about DNA is that it is the main form of nucleic acid. Also, it carries genetic information and controls reproduction. Another thing I learned is that proteins are made up of amino acids. This is important to know about because our body is full of DNA.

We learned about the size order of cell parts by brainstorming with our groups. Here's the list our group came up with

1. atoms
2. molecule
3. adenine
4. base pairs
5. strand DNA
   
6. chromosome

This is important because an experiment can be completely inaccurate if the person conducting the experiment got one of these items mixed up with another.

We learned about how a cell compares to other things by creating an analogy. For example, I said that a cell is like a house. Ribosomes are like light bulbs and the house structure itself is like the cell wall. This is important to know because when trying to think of an organelle's function, you can think about the analogy and what each part of the home compares to in a cell.
