8.7 Mutations Notes

Gene Mutations:
  • Mutations that affect a single gene
  • POINT MUTATION: one nucleotide is substituted for another DNA. May be fixed by DNA Polymerase
  • FRAMESHIFT MUTATION: insertion or deletion of a nucleotide in a DNA sequence, SHIFTS the entire sequence

Chromosomal Mutations:

  • Affects the entire chromosome (many genes)
  • GENE DUPLICATION: caused by exchange of unequal segments during crossing over. One chromosome has 2 copies of some genes and the other has no copies.
  • TRANSLOCATION: movement of piece of 1 chromosome to a non-homologous chromosome.

Potential Impact:

  • Chromosome mutations typically have a large effect on an organism
  • Point mutatiosn may result in premature STOP codons or amino acids with very different properties from the correct amino acid

Silent:

  • Some mutations have no apparent effect.
  • A point mmutation may not change the amino acid coded for.
  • Even if a change occurs, it may be in the non-coding region that has no apparent effect.

Mutagens:

  • Agents that can change DNA.

Thursday & Friday

Thursday: notes on mutations and some practice problems.

Friday: Ch. 8 Quiz and more time to work on test corrections.  As of Friday, you may check out a quiz to take from the room HOWEVER you need to have started your corrections in class.

Next week:

Starting Frogs!
I'll have a calendar for you.  If they make the proposed changes to class scheduling, there will be a LOT to change.

Good job in the lab!  Most of you did a great job with all the tasks you needed to accomplish.

If you missed the lab for any reason, it will be available Monday and Tuesday after school.

Answers to the Dye Lab are due Tuesday.

We're going to start the DNA lab on Monday.  It takes a few days to do it all - on Monday you'll get your DNA together and flow chart all the parts.

Tuesday you'll run gels and stain the previous class' gels (it takes more than a period to run them).  Wednesday morning period 1 will stain the gels from period 6.

We'll start analyzing the gels on Wednesday.  I'm planning that we wrap up the electrophoresis series and chapter 9 on Thursday and the you take the test on Friday.  Whooosh another week.

Have a great weekend, (make good choices!), you've earned it!

Friday

Today you are doing the Dye Lab - Dye Lab answers are Due Monday for Check Off and will be turned in with the next test.

You need to be efficient. Consider it a test for next week's time efficiency in lab.

We have one or two more labs after this (depending on how the timing works out) with electrophoresis.

Afterwards, there will be a test over all the labs/chapter 9.1 and 9.2. As of right now, this is tentatively for Thursday May 7th, but this could change.

Along with the next test you will be turning in:

  • Electrophoresis Lab
  • Dye Lab
  • DNA Lab
  • Study Guides CH. 9.1, 9.2
