Today we watched a video on genetics. We took notes on the video. He is going to collect the notes.
- We inherit genetic material from our parents.
- A monk name Gregor Mendel created experiment to figure out how this happened.
- He did an experiment using peas like our pea soup simulation.
- Each parent contributes one factor.
- the factors are genes.
- they can tell what the offspring might look like, but they can also pass some diseases.
- Morgan started working with fruit flies to experiment.
- Morgan took a fruit fly with red eyes and one with white eyes.
- The offspring had red eyes.
- All of the flies with white eyes where male.
- Gender is determined by chromosomes.
- Morgan found out that the eyes and x chromosomes had some relationship.
- diseases are caused by problems with genes.
- George Beetle worked with Morgan.
- Beetle took bread mold and experimented with it.
- Beetle aerated the chromosomes and the mold didn't grow.
- When Beetle added the nutrients the mold started to grow again.
- This showed that genes did more that give the characteristics to offspring.
- Barbara Miclintok was a scientist.
- Miclintok researched the genetics of maize.
- The color showed where the break in the chromosomes occurred.
- The color would show up in different parts of corn.
- Transposons are in all different things.
- Miclintok's work was ignored.
- Alford Hershey and Martha Chase found out whether it was the protein in the bacteria or DNA that caused viruses.
- They found out that it was DNA.
- James Watson were finding out about DNA.
- He made a 3-D version of DNA.
- He got a a x-ray of the DNA and finished the structure.
- They found out that it was a double helix.
- People knew that DNA made protein.
- Scientists found that cells with lots of protein had lots of RNA.
- Scientists found out that mRNA translated instructions from DNA and made protein.
- They found out that when they where aligned with triplets it made proteins.
- The triplets were amino acids.
- Merinbourg found out how to decipher the genetic code.
- Certain types of bacteria had enzymes that stopped viruses from taking over the bacteria.
- Smith found out that the enzymes cut the DNA in the place it was.
- Through a process called alternative splicing RNA can make more protein.
- Jeffreys was a detective.
- Jeffreys found a DNA variant called mini satellite DNA.
- DNA fingering was used in Jeffrey's case.
