Question: Ribosomes found in bacterial cells consist of two subunits, a small subunit (30S) and a large subunit (50S). “S” stands for Svedberg units, which indicated the relative sedimentation rate in a centrifuge for a particle of a given size and shape. The small ribosomal subunit consists of a single 16S rRNA molecule plus 21 proteins (chains of amino acids), while the large ribosomal subunit consists of two rRNA molecules (23S and 5S) plus 34 proteins (chains of amino acids).
TASK:
1. Make a diagram of a bacterial chromosome (genome) and label on it the places where the genes are for all of the rRNA molecules and prteins that are used to build a bacterial ribosome.
2. AID to the diagram ALL of the RNA molecules that will be transcribed from these genes. Indicate a single RNA transcript from each gene
3. AID to the diagram ALL of the protein molecules that will be translated from the RNA molecules. Indicate a single protein from each translated RNA.
4. Indicate on the diagram how the RNA molecules and proteins come together to form the functional small and large ribosomal subunits in a bacterial cell.
5. Last, how does ribosome assembly differ in eukaryotes?
Im really confused on what to do here. I know that I need to label a genome with 30S, 50S, 16S rRNA with 21 proteins, 23S, 5S and 34 proteins. What Im stuck on is what a bacterial chromosome looks like and how to locate these molecules and proteins on the genome.
