The trees dont take in co2 cause there are none cutting off the oxygen cycle
The ground finches adapted to have larger beaks to eat the bigger seeds in the drier seasons. This means over the years only the bigger beaked finches could survive to reproduce.
DNA is condensed by a certain amount just on its own, just by its own interactions within the DNA molecule,..but whne proteins get involved it gets condensed 30000 fold
<span>what happens is that proteins called histones are like hockey pucks, and DNA wraps around it 1.5 times and then goes to another histone and wraps around that so that it looks like beads on a string (i hope that makes sense, its the only way to describe it) </span>
<span>these histones condense this DNA a lot, and when the histones get methylated then the DNA packs together even closer to get heterochromatin (VERY densely packed DNA)...the theory here is that DNA has a net negative charge due to the phosphate groups in the DNA backbone and doesnt allow the DNA to come together as closely as it could (like charges repel like charges), but when histones are methylated, the negative charge on the DNA is masked by the methyl groups and DNA can come together closer </span>
If you observe the activity of methylated DNA, you would expect the change in the activity of DNA molecule.
<h3>What is the activity of methylated DNA?</h3>
DNA methylation is a process by which methyl is added to the DNA molecule which can change the activity of a DNA without changing the sequence. When it is located in a gene promoter, DNA methylation acts to repress gene transcription.
So we can conclude that If you observe the activity of methylated DNA, you would expect the change in the activity of DNA molecule.
