Introduction to Heredity Video Questions:

Video:                   “Monohybrids and the Punnett Square Guinea Pigs”

By:                          Amoeba Sisters

1.       Guinea pigs obtain their genes from                                       .

2.       What is the definition of an allele?

3.       Alleles are represented by                                          .

4.       How many alleles do you have per gene? (THIS IS NOT IN THE VIDEO. THINK!!!)

5.       Hairless guinea pigs have how many alleles for the gene, Hair?

6.       What is the genotype of the hairless guinea pigs?

7.       When do recessive alleles show up?

8.       A dominant allele is represented by                                        .

9.       What is the definition of genotype?

10.   What are the 2 possible genotypes for guinea pig without hair?

11.   How many alleles are necessary for a dominant trait to show up?

12.   Provide 2 homozygous genotypes.

13.   Provide 1 example of heterozygous genotype

14.   What is a monohybrid cross?

Cell Cycle and Mitosis

Please provide a written description of each phase of mitosis along with a comprehensive drawing of each phase as you watch the Video below.  Also answer VII) Results of Mitosis from today's handout.  As usual, please use your resources to help with this assignment (internet, textbook, and/or additional videos). The handout from today's class can be obtained here.

Transcription Model Guidelines - Fall 2015

I) Organization:
Divide notecards, foam board, poster board, and/or cardboard etc. into 4 sections. Alternatively, each of the 4 sections can also be placed on separate notecards, poster board, and/or cardboard if you so choose.

Section1:
Transcription Location/Starting material/Product/Destination of product

a. Model of DNA structure showing the deoxyribose and phosphate backbone as well as nitrogenous bases.

b. Clearly label each region of the DNA (Promoter, Start codon, Exons, Introns, Stop Codons)

Section3: Initiation

Section4: Elongation

Section 5: Termination


II) Scientific Accuracy:
For each phase of Transcription, generate a model that represents each step of the phase.

INITIATION:
1. Binding of RNA Polymerase to DNA
2. Unwinding of DNA from chromosome
3. Breaking of hydrogen bonds between complimentary base pairs of DNA
4. Start transcription (assembly of mRNA nucleotides) at start codon of DNA

ELONGATION:
1. DNA sequence being transcribed
2. DNA strand used as template to assemble pre-mRNA molecule
3. Sequence of pre-mRNA molecule
4. Labeled introns, exons, stop an start codons on pre-mRNA molecule

TERMINATION:
1. Removal of introns from pre-mRNA
2. Piecing together of exons of pre-mRNA
3. Addition of 5’Cap and polyA tail

MUST CLEARLY LABEL ALL PARTS OF MODEL!!!!!

DNA Transcription Homework - UPDATED!

Homework tonight involved two phases:

Phase 1. Read the following article on this website and summarize each paragraph into summary statements and diagrams (Potential quiz tomorrow)

(In case the link to article does not work, the website is listed as follows:
http://www.nature.com/scitable/ebooks/essentials-of-genetics-8/126042256#bookContentViewAreaDivID)



Phase 2. Watch the Video for the Summary of Transcription.  This video is located at the bottom of the article and answer the following questions:

a. What is the name of the region of DNA that RNA polymerase binds to in order to initiate transcription?

b. Does the newly synthesized mRNA ever bind to parental DNA strand?

c. Why are some mRNA regions "spliced" out of the final mRNA product?

d. What is attached to mRNA in order to signal the exit of mRNA from the nucleus?
