DNA is responsible for carrying the genetic information of a cell and have thousands of genes. Each gene may serve as an ingredient on how to build a protein molecule. Proteins carries out important tasks for the cell functions or can also serve as building blocks. The flow of information from the genes decides the protein composition and hence, the functions of the cell.

The DNA is placed in the nucleus, organized into chromosomes. Every cell must contain the genetic information and the DNA is therefore duplicated before a cell divides (replication). When proteins are required, the corresponding genes get transcribed into RNA (transcription). The RNA is first processed so that non-coding parts are removed (processing) and is then transported out of the nucleus (transport). Outside the nucleus, the proteins are made based upon the code in the RNA (translation).

Therefore, DNA, RNA and protein all are interconnected to many extent.

The central dogma of molecular Biology goes DNA to RNA to Protein. Describe the processes of transcription and translation. (in 2-3 sentences for each). Question 2: RT-PCR (real time - PCR) is a technique we can use that measures the amount of RNA in a cell at a given time. This allows us to see what genes are being "expressed" in a cell. Briefly explain how RT-PCR is being used to determine if people are positive for Covid-19.

The textbook presents a very simple, linear scheme of the central dogma of molecular biology (text page 500), but is explicit in noting the simplicity of the original concept and exceptions to it. Which of the following would NOT be reasonable additions or modifications that could be made to this simple linear scheme to account for experimental data?

1. What is the “central dogma” of biology? 2. What are the three differences between RNA and DNA? 3. What is the process of transcription? 4. Where does transcription occur? Why? 5. What are the three types of RNA? What do they do? 6. Explain the process of translation. How do the different types of RNA work together? 7. What is a codon? 8. How does a ribosome know where to start and stop translation?

The Central Dogma of Biology states that DNA is turned into RNA, which is turned into proteins. Is this rule infallible? Think of RNA viruses and telomeres when writing your response.

How does the central dogma of biology relate to the idea that structure defines function?
