Unit 6 DNA, RNA, Protein Synthesis and Mutations
Objectives
- To Understand the basic structure of nucleic acids; DNA and RNA?
- To understand the importance of DNA replication ?
- To understand are the different types of RNA, and what are their functions?
- To know what occurs during transcription and translation?
- To find out what happens when changes occur in the DNA?
You need to watch the following videos and then go to schoology and answer the questions. This is due the next time we meet in class. If this is not done, you will have mandatory tutoring.
Schoology Link-If you need the code, go to the biology semester 2 section for the codes.
DNA
DNA-Deoxyribose Nucleic Acid.
DNA is the blueprint for all living things. It is our genetic material. The biomolecule associated with DNA are Nucleic Acids. The basic units in DNA are the nucleotides.
The structure of DNA is made up of many nucleotides. The shape of the DNA molecule is known as a double helix, often described as a "twisted ladder."
DNA is found in the nucleus of Eukaryotic cells and in the Cytoplasm of Prokaryotic cells. DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
In this unit we will learn more about DNA. Watch the video on DNA as well as the power point for better understanding.
Things we will be doing to understand DNA
Review biomolecules
Build a DNA strand and understand the components that make up DNA and its structure
Understand DNA replication and it's importance.

Transcription and Translation and Protein Synthesis
The following power point explains Transcription and Translation and Protein Syntheis
It is now time to practice Transcription and Translation so that you can do Protein Synthesis. You will be creating Snorks. Going through Transcription and Translation you will find the characteristics needed to create your Snork. When you build your Snork, you will make a model of what your Snork looks like. You can use construction paper to create your Snork or you can use clay do make the model.
Creating A Snork
Make sure that you are dong transcription, translation and Protein Synthesis to build your Snork. From the given DNA strand, you need to make:
mRNA
tRNA
Amino Acid
mRNA
tRNA
Amino Acid

Mutations
Mutations
Sometimes mistakes occur when DNA is copied. This can create what is called a mutation. Sometimes mutations can be harmful, sometimes mutations can be beneficial and sometime mutations don't create any change.
Mutations can affect the gene, creating a Gene Mutation, or it can affect the whole Chromosome, causing a Chromosomal Mutation.
