He called the things he saw cells. Though they were dead, he was still the first person to see cells upclose. <br /> <br /> Cell theory is made of 3 basic ideas. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. All living things are made of cells. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. All cells come from preexisting cells. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.

He spent hours studying gravity and how it effects motion. This helped him developed his 3 laws. Layer Albert Einstein said that space bended around it, causing thing to &quot;roll&quot; into the bend.

The bases can be adenine, thymine, guanine, &nbsp;and cytosine. A microscopic machine runs along DNA and copy it,only replacing thymine with uracil.<br /> <br /> This copied strand is called mRNA (messenger Ribonucleic acid). This strand is taken to rRNA(ribosome).<br /> <br /> This part is why your arrangement of DNA matters<br /> <br /> In the ribosome tRNA(transfer Ribonucleic acid)with arranged bases on it is attracted to the base it is attracted to.<br /> <br /> Adenine goes to thymine/uracil<br /> <br /> Cytosine goes to guanine<br /> <br /> Amino acids on the end of each tRNA link together to form a chain. This chain fold up to form proteins, making you who you are. Other https://www.kidzsearch.com/questions/363353/what-is-dna Wed, 25 Sep 2024 00:20:51 +0000
