Assuming that each nucleotide in an mRNA is 0.34 nm long, how many triplet codes can simultaneously occupy the space in a ribosome that is 20 nm in diameter?

Hi everyone. Let's take a look at this practice problem together. How many? 0.6 nanometer long nucleotides can fit into a 30 nanometer diameter ribosomes. So this is a straightforward math calculation. There's no tricks. It is as simple as it sounds. So the number of nucleotides that can fit in this ribosomes is going to be 30 nanometers divided by 0.6 nanometers. Which will give you 50 nucleotides. So the answer is going to be be 50 nucleotides would fit into a 30 nanometer diameter of Aiba Zone. Now there is a variation you can see for this type of question and it might say how many code ons are there That can fit in this 30 nanom diameter ribosomes. And in this instance you would take the 50 nucleotides and divide by three because there are three nucleotides in a code on. And that would give you 16.66 code ons. So this is just an example of a variation you might see on this question. But for us, our answer is going to be b 50. Alright, everyone, I hope you found this helpful and I'll see you soon for the next practice problem
