S. ynthesis Exam Review. DNA & RNA. What . is DNA replication? Where does it occur in the cell?. WHEN DNA MAKES A COPY OF ITSELF.. IN THE NUCLEUS!. What . is the function of genes (segments of DNA. GO TO . BIOINTERACTIVE WEBSITE. DNA replication questions. Why is DNA replication so important?. In what part of the cell cycle does DNA replication occur?. What enzyme brings in the new DNA nucleotides that form complimentary pairs with the old DNA strand?. DNA .  RNA  Protein. 2 Major Steps. Transcription. – DNA is transcribed (copied!) into single stranded mRNA . (DNA code transcribed into RNA code). Translation. – mRNA is translated into protein (amino acids). Chapters 16 and 17. Before the end of the semester we will be covering…. Historical DNA experiments. Structure of DNA/RNA. DNA Replication. Protein Synthesis (Transcription and Translation). Mutations. DNA is made of long chains of . nucleotides. each nucleotide has 3 parts:. 1. . deoxyribose. . sugar. 2. . phosphate group. 3. . nitrogenous base.  . DNA Components. there are . 4. possible nitrogen bases:. Objectives. Explain the purpose and process of transcription and translation. Recognize that gene expression is a regulated process. Describe the roles of DNA and RNA in cell differentiation. Identify and illustrate changes in DNA and evaluate the significance of these changes. Learning Objectives. Identify. . the genetic code and explain how it is read.. Summarize. . the process of translation.. Describe. . the . central dogma of molecular biology.. The Genetic Code. RNA has four bases: adenine, cytosine, guanine, and uracil. These bases form a . Learning Outcomes. At the end of this . topic . you should be able to . . Outline the steps in protein synthesis.

Using one half of the a DNA helix, show what the correct pairing would be, skip lines.. ATT CGT TAC CAC CTC. TAT TAG GCA ATA TTC. GTG TGA TTA ATA GCC. CTA AAG GAA TAG GAT. GAT GAA TAC CCA CGA. Gene Expression. When a cell “reads” the DNA, it doesn’t directly say for example blue eyes.. . What the DNA actually says is what types of proteins to make, when to make them, & how much of them to make.. codons.  that define specific amino acids. Many questions pertaining to this genetic code were posed in the late 1950's:. • How many RNA nucleotide bases designate a specific amino acid?. If separate groups of nucleotides, called . 69NB. Directions:. Using the DNA strand as a template, transcribe mRNA. Make sure to use the correct Nitrogen bases.. ATA CCT TAA CGC GTC. TAT TAG GCA AAA TTC. GTG TGA TTA ATA GCC. CTA AAG GAA TAG GAT.
