Part I. Introduction and Genetic Engineering Biotechnology Part I. Introduction and Genetic Engineering

Standards: BI4. c. Students know how mutations in the DNA sequence of a gene may or may not affect the expression of the gene or the sequence of amino acids in an encoded protein. BI5. c. Students know how genetic engineering (biotechnology) is used to produce novel biomedical and agricultural products. BI5. a. Students know the general structures and functions of DNA, RNA, and protein.

Objectives: SWBAT explain the structure and function of DNA, RNA, and proteins. predict the physical characteristics of an organism based on its genetic make up. understand the general pathway by which ribosomes make proteins. understand how altering an organisms genetic make-up changes the proteins the organism produces.

How can we “cure” genetic disorders? Biotechnology is an emerging field that could potentially develop cures for genetic disorders. Biotechnology could help these people through technologies such as gene therapy or gene replacement. It may be possible someday to repair, replace, or insert the proper genes into human’s DNA.

How is Biotechnology a part of your life? Medical research Consumer products (clothing) Forensic Science (crime scene investigation) Maury (baby daddies-DNA fingerprinting) Genetically modified foods (you eat them on a daily basis)

What is Biotechnology? Bio=life Technology=usage and knowledge of tools and crafts Biotechnology- technology that uses biological systems, living organisms, or products made from living organisms to make or modify products or processes for specific use

Genetics Review Genes code for proteins (transcription and translation) Proteins-make-up physical characteristics Changes in the DNA sequence will affect the genetic code (mutations) If the genetic code is changed then a protein can be changed This can change an organisms’ physical characteristics

What is genetic engineering? Altering genes to produce a protein Changing of an organism’s DNA to give the organism new traits Transgenic organisms-has one or more genes from another organism inserted into its genome Uses-medication and genetically modified crops

Summary Questions: What are some common uses of biotechnology? How can biotechnolgy be used to cure genetic diseases? How can altering an organism’s DNA change the proteins the organism produces?
