Molecular Biology of the Gene- Introduction

You will review the macromolecules and the monomers:
Macromolecules                                                               Monomers
1) Proteins                                                                        Amino acids
2) Carbohydrates                                                             Glucose
3) Lipids                                                                            Fatty acids and glycerol
4) Nucleic Acids                                                               Nucleotides.

The bonds holding amino acids together are called peptide bonds.  A polypeptide has less than a 100 amino acids bonded together.  More than a 100 amino acids bonded together is called a protein.  (The words proteins and polypeptides are used interchangeably and some textbooks do not distinguish between them.)

You will also be introduced to Viruses working as saboteurs within our cells.

Bacteriophage: "Bacteria eaters"

Notes, Vocabulary, and Labs will be graded.

You will turn in you work to be entered in the computer. Make certain to include the labs:
Determination of Genotypes from Phenotypes and Fingerprint Lab: Incomplete Dominance.

Sex-Linked Worksheets

Tuesday, March 12, 2019

Students worked individually on Sex-linked worksheets.

Wednesday, March 13, 2019
Graded the worksheets from yesterday.

Fingerprints and Incomplete Dominance

Lab: You will examine your fingerprints and those of your classmates to identify the different phenotypes.

Worksheet- Punnett Square Practice.

You will work individually on two different Punnett Square worksheets.

Lab: Determination of Genotypes from Phenotyoes in Human

Thursday, March 7, 2019
You will work in your lab groups to examine your phenotypes such as widow's peak, or straight hair line, and hitchhiker's thumb or no hitch hiker's thumb.  Have fun.

Sex- Linked or X- Linked Genes

You will learn about X-linked inheritance.  In addition, we will review and grade the information on the worksheets from yesterday.











Some examples of X-Linked traits are:
1) Red-green colorblindness
2) Balding
3) hemophilia
4) Some forms of mental retardation                                                                                                                           

Punnett Square Practice

Punnett Square Practice.  You will work individually on two different worksheets to test your understanding of the subject.

Those of you who will be absent should make up the worksheets immediately on returning to school. It will be too late to make up the work after they have been returned.

Dihybrid Cross

The following topics will be covered in class;
1) Recessive conditions such as Tay Sach disease, cystic fibrosis, and sickle cell anemia
2) Dominant conditions such as achondroplasia ( Dwarfism), and Huntington's Disease.
3) Introduction to dihybrid Cross.

 

Punnett Square Practice Worksheet

You will work individually to predict the genotypes of the members in the pedigree charts
