R-R-R-R-Review for G-G-G--Genetics (oh hey, I'm Ke$ha)

SO BASICALLY
in class we got some papers passed back and we went over mutations. We also got to ask questions about the test (not really). We didn't have time for the 60 minute video Mrs. Stein planned on having us watch (surprise).

NOW ITS TIME FOR R-R-R-R-R-REVIEW!!!!!

Chapter 12: DNA

What makes up a Nucleotide?
-a nitrogen base, a sugar, and a phosphate group

What are the Nitrogen bases in a Nucleotide?

-Adenine, Guanine, Cytosine, and Thymine.

What is the sugar in a Nucleotide?

-Deoxyribose sugar

What do each Nitrogen base pair to? What type of bond hold them together? Why is that bond weak and not a strong bond?

-Adenine to Thymine, Guanine to Cytosine, and Thymine to Adenine and Cytosine to Guanine. A Hydrogen Bond and it is weak because during replication the DNA polymerase needs to be able to separate the double helix easily.

Summarize the events of DNA replication:

-Strands unwind

-hydrogen bonds break (With help of enzyme DNA polymerase)

-New strand is proofread

-sugar phosphate bonds join nucleotides together

When in a cells life does DNA replicate? Where in the Cell does it replicate?

-During the S phase of interphase and in the Nucleus.

Following DNA replication the molecule results in 1 new strand and one original strand.

Write the complimentary Bases for the following strand of DNA

A- T

T- A

G- C

A- T

C- G

G- C

A- T

T- A

Chapter 13 Review-RNA & Protein Synthesis

Explain how RNA differs from DNA. Name 3 main types of RNA.

-RNA is only one strand, and it does not have Thymine, instead it has Uracil. rRNA, mRNA and tRNA

Describe transcription and editing of RNA.

One strand of DNA serves as a template for the synthesis or mRNA (DNA: TACCAGGTT) ----- (mRNA: AUGGUGGAA)

Also, you have to be able to use the Codon Chart.

Summarize translation: Picture below

Incase you haven't NOTICED, your homework is to study for the test tomorrow. AND YOUR TRIBUNE ARTICLE IS DUE TOMORROW

Have a great day people!

P.S THIS TOOK ME FOREVER AND I HAD ALOT OF HOMEWORK TO DO, SO I WAS NOT VERY HAPPY.

but to end on a good note, TOMORROW IS TECHNICALLY FRIDAY!! YAY!!!!!!!!!!

and the next scribe is.....

Yvette! all you have to write about is our test. (idk if i should've chosen a scribe but whatevs)
