Is it because in order to form many ribosomes, there will need to be a high number of rRNA, in addition to the high number of proteins produced?

One.

I understand that, but each of those ribosomes is made up of rRNA and proteins. So why would you need more copies of the rRNA than protein?

I'm really not sure. I would think none because the ribosomes, and thus their rRNA are recycled after translation.

A eukaryotic ribosome has 4 different rRNA molecules and about 82 different proteins. There is a single copy of the gene for each of the proteins; however there are multiple copies of each rRNA gene. Why does the genome contain more copies of each rRNA gene than for each ribosomal protein gene...

Are you referring to the mechanisms of topoisomerases and ligases being in common?

1. A. E.coli DNA ligase can act as a DNA gyrase in the presence of high concentrations of AMP. Explain. B. Would you expect the E.coli ligase/AMP combination to resemble type I or II topoisomerase, or neither. Justify. C. Would you expect human DNA ligase to act as a topoisomerase in the...

Thank you so much, I couldn't find information on this anywhere!

Can DNA adopt an A-form helix, and can RNA adopt a B-form helix. If so, under what conditions, and if not, why not? The only idea I have so far is that low humidity will help form the A form, and high humidity forms the B form. However, can humidity change in our bodies? I'm lost here.

Well, a typical cell is around 1 micrometer, or .001 mm. So, if we need volume, I would assume a cell to be roughly square and the volume to be .001*.001*.001 = 1*10^-9 mm^3

1. dTTP is used in DNA synthesis. dTTP concentrations are mM, while a particular chromosome has only two copies. Estimate what fraction of the complete diploid set of chromosomes will be copied if at the start of DNA synthesis all new production of dTTP is blocked and the initial concentration...
