 * 1) ===== What are the 5 elements that make up DNA? =====
 * 2) ===== What is the function of DNA from day to day? =====
 * 3) ===== Describe how long strands of double-helical DNA fit into the nucleus of a single cheek cell. =====
 * 4) ===== What was the purpose of using the cell lysis solution? =====
 * 5) ===== Why does the DNA become visible once the alcohol is added? =====
 * 6) ===== If DNA is so thin, how is it that we are able to see it during this simple lab exercise? =====
 * 7) ===== Why is DNA referred to as your genetic fingerprint? =====
 * 8) ===== Give some examples of how DNA is used everyday. =====

=DNA Model =
 * 1) =====The 5 elements that make up DNA is carbon, Oxygen, Hydrogen, Nitrogen and Phosphorus.=====
 * 2) =====The function of DNA from day to day is thatit controls the day to day functions of your cells.=====
 * 3) =====The long strains of DNA fit into the nucleus because it folds and bends to fit into it.=====
 * 4) =====The purpose of using the cell lysis solution is because it help break the DNA out of the nucleous.=====
 * 5) =====The alcohol help made the DNA visible because it precipitates in the solution.=====
 * 6) =====You can see the thin stain of DNA because of the alcohol added to it.=====
 * 7) =====It is known as your genetic fingerprint because everyone has different finger prints and DNA is different for everyone.=====
 * 8) =====Some examples of how DNA is used in everyday life it in crime investigations, identifying new types of animals, and in identifying people.=====

DNA replication is important because without it we will not be able to pass our traits to our children. And if we can not pass them to our children then we will be wiped out in a matter of years and our kind will not be living anymore.

In the first step of DNA replication is when a enzyme called helicase brakes the hydrogen bonds from the DNA into two parts. One is called the leading strand and the other is called the lagging strand and they go in different direction during DNA replication. This makes the DNA into a replication fork. Then after that the protein called single stranded binding protein keeps strands from binding together. Then primase binds and forms a starting point in the DNA. Last but not least, an enzyme called polymerase binds and replicates the DNA. In the lagging strand, fragments called Okazaki fragments are formed and a enzyme called ligase joins the fragments together. The Okazaki fragments are used to synthesize the lagging strand. And with all of this information this is how a parent can send there DNA to there children so that they look like there parents.

And if the DNA replication went wrong then there is 3 things that might have happened. They are all called mutations. The first mutation is when there is a thing called substitution. Substitution is when there is one of the bases paired with the same base. A example is if Adine and Adine was paired together. Another type of mutation is called deletion. Deletion is when there is a base that isn't paired with anything. And the last type of mutation the occurs in DNA replication insertion. Insertion is when one base is paired with two of the other bases. And example is if Admine is paired to thymine and thymine. The results of the mutations might be autism, down syndrome, and mental retardation

TRANSCRIPTION- DNA is made into mRNA. mRNA then leaves the nucleolus into the cytoplasm

TRANSLATION- rRNA makes Ribosome which binds to the mRNA and reads it. tRna match anticodon to codon and amino acids attached to tRNA bind with peptide bond. Ribosome hits stop codon and completes protein.

=Diaper Dissection Report= First, we cut the diaper in half. Then we cut out a square from the one half. The square held 28mL of water before it leaked. Then we took the other half an saw how much water it held a total of 256mL! We identified the layers and their functions. The top layer feels plush and is used to cover the absorbent layer. The middle layer feels like silk and absorbs the water. The bottom layer keeps the water from leaking and is soft like cotton. the absorbent layer, once wet, can be washed into the drains and clog them.
