The restriction enzyme EcoR1 makes staggered cuts at 6 nucleotide palindromic sequences while the enzyme HaeIII makes blunt end cuts in middle of 4 nucleotide sequences. If a given DNA sample is digested by these two enzymes in separate reactions which one would generate more fragments? Explain your reasoning.

You have discovered a strange new enzyme that can carry out demethylation on methylated lysine R-groups as well as on 5-methylcytosine, despite the very different structures of these molecules. Using this method in conjunction with gene expression analysis, is it ever possible to differentiate whether a gene is regulated by histone methylation or by DNA methylation? If so, give an example. If not, why is this not possible?

Which one is typically NOT afeature of a prokaryotic restriction enzyme?

What is the difference between DNA methylation and histonemethylation? I understand that both include the repression of genesand that DNA methylation occurs at CpG islands. But when doeshistone methylation occur and not DNA? VIce Versa? Please includeRITS/RISC complexes in the answer as that is involved.

You found a new mutant C. elegans worm with an abnormal histone H2A gene. This novel histone mutant is predicted to cause the nucleosomes to bind an extra 12 bp of DNA compared to wild type. You perform experiments to release the core nucleosomes from linker sequences. What size DNA fragments would you expect wrapped around the core nucleosome in wild type and mutant worms?

Regulation laws of a library:

Research Local Laws-

Use the internet to find out which laws apply to public library. Find two or three measurements to test. For example, how wide must a doorway to a library be to accommodate a wheelchair? How large must a restroom stall be? Where must fire alarms or light switches be placed? What about drinking fountains or sinks?

Measure the doorway, sink height, or other factors that you have chosen. Record your results and compare them to legal requirements.

The speech will be discussing about what’s in the bolded words above 👆🏼. You are comparing the laws to what they have in a library and if it meets the requirements. If it doesn’t tell the building owner why.

Pretend to write to the building owner of your community library. And explain what did or didn’t meet the standard requirements of a library. 👇🏼

Create a short speech to send to the building owner of a public library. Describe what you found. Explain why the regulation you chose is necessary. For instance, it doesn’t matter if a bathroom stall can accommodate a wheelchair if the only doorway to the bathroom is too narrow for the person to reach the stall. Using the informal presentation techniques you learned about in this unit, do your best to present your ideas in a professional way.

Why are there so many histones found in the nucleus?

What is the role of histones in nucleosomal structure?

one of the mutations that you found in your genomic library of groodie's DNA showed that they had a mutation of a histone that holds a nucleosome attached to the DNA. Otherwise the nucleosome is very similar to the human. What is the structure of the groodie's nucleosome? what histone was mutated in them?

so me and my friends are debating this question and we're stuck between H1 or H3

I say H1 and that nucleosome structure doesn't change but formation of 30nm solenoid structure is inhibited

but my friends say H3, and in the case of H3 they're saying the nucleosome will have looser DNA and so is less compact and cannot readily bind to the histone
