Test on transcription and translation
May 1, 2018

April 30, 2018
Class notes and vocabulary from chapter 10 will be collected and graded.
The class will practice for the test on Wednesday by working on a transcription and translation worksheet.

Introduction to transcription and translation. The class was taught how to transcribed the mRNA from the DNA. They also learnt how to read the genetic code chart.
The Image below shows the transcription of the mRNA from the DNA:
The nitrogenous bases present in the RNA are:
1) cytosine
2) guanine
3)adenine
4) Uracil
(The RNA is copied from the DNA molecule.)
April 16, 2018
The following pages from Biology; A Human Approach, ( the textbook assigned), will correspond to the lessons in class. Pages 516 - 532. (The genetic code chart can be found on page 530.
The class was taught how to copy the DNA.
The DNA is double helix.
The nitrogenous bases in the DNA are:
1) cytosine
2) guanine
3) adenine
4) thymine
The base pairing rule for copying the DNA is
Cytosine bonds with guanine ( C bonds with G)
thymine bonds with adenine ( A bonds with T)
Introduction to the chapter explained the role viruses played in identifying DNA as the genetic material.

Pages 496 - 515 from the BSCS Biology Book, ( The textbook checked out to you), will cover the topics covered in class since the start of Genetics.
Sex linked / X-linked traits explained.
Sex-linked / X-linked disorders affecting mainly males was also explained.
Examples of a few sex-linked conditions are: hemophilia, red-green color blindness, congenital deafness, Duchenne muscular dystrophy, and some forms of mental retardation.

Introduction to Gregor Mendel; The Father of Genetics
Introduction to dihybrid cross
In addition to his studying of single gene, Mendel also studied the phenotypic expression and segregation of two genes. This highlights his Law of Independent Assortment.
A dihybrid cross is a cross between two true-breeding parents that differ at two alleles.
For example: Peas that yellow and smooth crossed with peas that are green and wrinkled.
Let's make green and smooth the dominant trait.
Parental generation genotype:
ggSS x GGss
F1 Generation (First Filial Generation)
The phenotype : all green and Smooth
The genotype : GgSs
F2 Generation ( Second Filial Generation)
Results: 4 Different phenotypes.
Use the information explained in class and practice finding the phenotypes and genotypes of the F2 generation.
