Last Hoorah for Mrs. Maine

Well Mrs. Maine, it has been a wonderful year. From our little bio parties, and Sicki and I making fun from the back of the room, to actually learning a few things here and there. Hopefully Sicki and I can come in alot nex year and have some more fun, maybe pick on your homeroom students hahaha. We will definitely be in there the second day of school (if not the first). Well, see you next year! It's been great!

Monohybrid Cross and Probability
Pennies flipped one at a time
Heads total=52 and Tails total=48

Pennies flipped twice at a time
HH=28 HT=47 TT=25


Our 1st egg consisted of Red and Orange with 2 orange and 2 red starburst inside. Our second egg was orange and yellow with 2 orange and 2 yellow starburst inside.
What we already know:
What we still need to do:
Questions we have:
Answer to our questions:
There are 2 yellow starbursts and two orange starbursts in the one yellow and orange egg.
There are two red and two orange in the red and orange egg.
Each color/half of an egg represents a parent in some cases.
Each parent gives half the chromosomes to each kid.
Red and yellow make orange. Have to be pure. Orange has to be a mixture.
discuss with other groups on the color of their eggs and the starburst inside.
What color is the dominant trait?

If you had a yellow and a orange how could you get 4 orange eggs?

How can an all orange egg have yellow, orange, and red inside?
Red is the dominant trait.

The egg can have orange, yellow, and red starburst because in an all orange egg you have to have Rr which represents orange. which is a mixture of red and yellow because RR is red and rr is yellow and therefore can have red and yellow in an orange egg. If the egg is completely orange which means both parents have Rr, they can each give a R and a r.



Making a Protein: Model

Marylin_999999.pngThis is the two strands that are together with all the bases before they start to unzip.






splitting.jpgHere, the DNA splits to start the transcription/translation process.
mRNA.pngIn this step the mRNA comes in and transcribes the one strand of DNA, making the slight change of "T's" to "U's"
cytoRNA3760.pngNow the mRNA moves out into the cytoplasm and then into the ribosomes.
tRNA1234567.pngOnce in the ribosomes, the mRNA is translated by tRNA, and is formed into a new protein to be used by an area of the body.



Gel Electrophoresis

Who's Yo Daddy?

We have came to the conclusion that the father being tested is not the father because not enough of the DNA from the father matches the child.


Mitosis Drawings
Intherphase.png
In Interphase, DNA duplicates.
prophase747347.png
Prophase: Nuclear membrane disappears and chromosomes start to move towards center
metaphase1234321.png
Metaphase: The chromosomes line up along the center.


anaphase.jpg
The paired chromosomes separate, and now they start moving to the poles of the cells.

Telophase: the cell membrane starts to move in around the cytoplasm.

Cytokinesis is the splitting of the cells.







Replication Models


The double helix at the beginning of DNA replication. The Double helix starts to "unzip".

The double helix split into left and right.


zipping.jpgzipping.jpg
The helix joins together with a new base and "rezips" forming two new double helix strands.

An okazaki fragment is a newly replicated short fragment of DNA. The okazaki frament is created from the lagging strand, which is the strand opposite from the replication fork.

DNA ligase is a type of ligase that links together DNA strands that have a break between both the strands of DNA. DNA ligase has both applications in DNA repair and DNA replication.


Telomerase- Are enzymes that make specific DNA, they make the same sequence every time. TTAGGG which goes with
AATCCC

Transplanted cells - This is a process in which old ells are taken from your body, repaired and made healthy again, and infused back into your body. A stem cell transplant can help your body make enough healthy white blood cells, white blood cells, and platelets.


The cloned sheep was made using a nucleus taken from an adult cell and that was growing in a culture. The cell came from a 6-year-old donor and had been in the culture for several weeks. The cell had been lacking telomeres for several generations, so Dolly had telomeres that were only 80% the length of a normal 1-year-old sheep. Also, sheep that had been cloned from embryonic cells instead had shortened telomeres, but they were not as short as the others of Dolly. Because of Dolly’s short telomeres another question is added to the debate on cloning from adult cells, and it is unknown if the shorter telomeres would lead to a shorter life.

Telomeres- protects the end of a cell from destruction and they also protect from chromosomes becoming attached. They are essential to life of a cell.

Aging- as you get older the process becomes slower and you lose more cells than what you are making. When telomeres shrink they put a limited life span on the cells. Since you have a limited life span on cells you will lose more cells, causing you to age.


Cancer cells are very, very different from regular cells. It is able to divide indefinitely. Most cancer cells have gained the ability to make high levels of telomeres during the cell cycle. This means they are able to stop the shortening of their telomeres, which would mean the end of their lifespan.

Wavelengths and their light spectrum 750-(Infra)red, 700-red, 650-orange, 600-yellow, 550-green, 500-cyan, 450-blue, 400-(ultra)violet. Contrary to what the chart above states, we found that the shorter the wavelength the higher the energy, and the longer the less energy there is. That's why ultraviolet rays and those rays below that, such as gamma rays, are more dangerous to us than those wavelengths of the infrared and higher spectrum.

Exercise for health

Tyler vs. Sam
Sprinted for 60 seconds
Check ph for both
Compare.
Jenna timed them.
Marilyn recorded for Tyler and Shayna recorded for Sam.

Hypothesis:
If you are athletic, your pH will be lower than someone who is not athletic.

How we tested it:
We tested this by having Sam (athletic) sprint for 60 seconds against Tyler (nonathletic) in a closed environment.

Variables:
Sam was the athletic variable and Tyler was the nonathletic variable.

Results:
Sam's pH was 8.4 and after blowing in the pH for 60 seconds the pH was a light green color. Sam's pH after blowing into was 6.71. Before the exercise, his pH was 8.4. After doing the exercise, he blew into the straw and his pH was a darker green color and the pH measured 6.74.

Tyler's pH was also 8.4 and after blowing in the pH for 60 seconds, his pH was a darker light green and measured 6.73. Before the exercise, his pH was 8.4. After completing the exercise, his pH was a lighter green color and it was 6.68.

When Sam and Tyler were blowing into the bromothymol blue, and at 23 seconds, both Sam and Tyler's turned green. After the exercise, at the 42 second mark they both turned green.
