Protein Synthesis WebQuest - Transcription

Introduction

Welcome Student Geneticists!   

Essential Questions: How are proteins made from a DNA template?

Objectives: By the end of today's webquest you should be able to:

1) Identify the central dogma of genetics (DNA --> RNA -->protein)         

2) Describe the function of mRNA.                                           

3) Define transcription and describe and sequence the basic steps of transcription.                          

You have been choosen to work with a team of geneticists to determine if a mutation in a specific gene causes a disease. Today you will complete this webquest to learn about the first step of protein synthesis: transcription. Next longblock, you will learn about mutations and the second step of protein synthesis: translation. After you complete both webquests, you will be prepared to join the team of geneticists.

Process

Yesterday, you should have completed the pre-lab at the top of your handout (#1-7).

Today you will research and complete activities on three different websites to learn about transcription.

Website 1- Basic Transcription Activities-Click on the link below. Follow the directions on your handout to complete 8-9b.

MA Biology Curriculum Frameworks Addressed in this webquest:

3.2 Describe the basic process of DNA replication and how it relates to the transmission and conservation of the genetic code. Explain the basic processes of transcription and translation, and how they result in the expression of genes. Distinguish among the end products of replication, transcription, and translation.
