The Central DogmaBy the end of the week, I will be able to describe how genes allow for gene expression by reading about the Central Dogma, drawing a diagram and writing a paragraph to go with my analysis. Reference: The Central Dogma>
A. What is a central dogma ?The central dogma is when DNA turns in to RNA and then turns in to proteins . It is the explanation of the flow of the genetic information in the biological system of our bodies . Proteins are in the cells with makes our body function correctly .
|
B. What is DNA ?DNA strands are made of letters. DNA builds different part of cells. It is the carrier of genetic information. DNA is in all living organisms .It looks like a double twisted ladder called a " double helix " . Genes and cells make other molecules called protein.
|
C. What is a gene ?Genes are things that make our bodies fucntion properly. Genes are made of DNA. Each strand of DNA has genes in it. We need genes in our bodies to operate them. In our whole body we have about 25,000 genes. People mostly have genes from there parents which causes us to act and sort of look like our relatives.
|
D. Transcription and TranslationIn the nucleus the cell copys the gene into the RNA. DNA and RNA are very similar. RNA has 4 nucleotide boses . The protein machine in our body called the ribosome translates in to the amino acid . The stop Codons tell the ribosome when the protein is complete .
|
E. What is a protein ?Proteins are the " machines " in our body that makes everything work properly. Our bodies contain alot of cells and in each cell it has protein which makes the cell run properly . When we feel pain in our bodies we have cells called " receptor proteins ". Protein are large molecules with long chains of amino acid. We need proteins in our cells to help our hair grow , nails grow , work our body ect..

F. An example of gene expressionthe message from a gene is sent to a functional gene product.
