Sammy Sperm

Mr. Meiosis and Mrs. Meiosis gave birth to a sperm born on February 20, 2000 in Testi Hospital.  The Meiosis family decided to name the sperm Sammy. When Sammy the sperm was 5 months old, Sammy became lost and ended up in the Epididymis. Sammy learned and matured over this period of time. Sammy started his journey to find the golden egg. Before Sammy left, his dad told him to always go left. Sammy did not know what he was talking about.  He swam down to the Van Deferens Water Highway, he then reached Lake Bladder. There was a race to get to the other side of the lake, the winner would be able to find the golden egg and free dinner. Sammy won the race and ate at the Seminal Vesicle Diner. After Sammy has rested, Sammy continues his adventure to the Urethra Underwater Expressway. However, to go through the rough traffic he needed some supplies. Sammy bought semen at the Prostate Gland Acid Proofing Shop and lube from the Copwers Gland Lube Shop. He takes a spermship and launches into the air. After one month the spermship orbits into Vaginaland Sperm Station. Sammy realizes he is almost there and keeps on pushing to Uterusville until he is met with an intersections. He could either go left or right and he remembered what his dad was talking about. He turned left and found the golden egg and her name was Ms. Ovum. They loved each other so much that they merged and became a baby.

Bee Mutation Blog

Bee mutation A had 2 pairs of antennas instead of having one. This mutation is positive since the bees use their antenna to smell, feel and taste. Having 2 pairs of the antennas will provide a spare antenna if the other main one becomes damaged. Also, the abilities to smell, feel and taste will double.

Bee mutation B had a smaller sting than usual. This mutation is neutral because the size of the stinger does not matter, a small stinger sill does the same job by giving out venom when used.

Bee mutation C had no wings. This mutation is very negative, the prevents all the abilities of a bee. The bee will not be able to return home with pollen since it cannot fly back up to its hive. The bee would most likely die without the ability to fly.

This activity helped me realize that a little change can have a big effect or a small effect. There are a lot of variations of animals and it is very interesting what each of them do. I learned that mutations can affect the survival rate of animals.

 

DNA Bracelet

I had to make a DNA bracelet using string and cereal. Each coloured cereal represents a combined base letters to make it into a codon. Green = adenine, purple= guanine, yellow = thymine, and pink = cytosine.  The 3 pieces of cereal makes it a letter in the alphabet of the DNA alias code. The entire message of the bracelet represents the DNA sequence. My name represents multiple codons which make up amino acids. The mRNA fits through the pores in the nuclear and the ribosome holds onto the mRNA then, reads the instructions and links to the amino acids. image

DNA Model

In this experiment, I had to make a model of a DNA using liquorice, marshmallows, and toothpicks.  The liquorice represents the double helix. The backbones of the DNA are made up of sugar and phosphate. The marshmallows in the photo represents the bases which are adenine, thymine, guanine, and cytosine. Pink is cytosine, green is guanine, yellow is adenine and orange is thymine. The “rungs” or base are ALWAYS bonded in a certain way, adenine (A) double bonds with thymine (T) and cytosine (C) triple bonds with guanine (G). This activity helped me in a visual way. Since I have not seen a real DNA, and this gave me an understanding of what a DNA is shaped like and the base bonds.
