Peppered Moths: An Example ofNatural Selection. ... Light-colored peppered moths were no longer well camouflaged on the darkened tree trunks. The dark colored moths, however, were well camouflaged. Because predators were able to spot the light moths more easily, the darkmoths were more likely to survive and reproduce

Differentiate bet prokaryotic and eukaryotic cells

masha68 [24]

There are differences between Eukaryotic and Prokaryotic cells. This difference is considered to be the most important distinction between groups of organisms. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. Both plant and animal cells are eukaryotic cells.

Part A If you want to affect chromatin packaging, which amino acid could you mutate to affect both histone acetylation and methy

attashe74 [19]

Answer:

Lysine

Explanation:

lysine residues on the histone tails of the octamer cn be activated by both acetylation and methylation patterns to influence accessibility or silencing of the genes respectiviely. for example, acetylation of H3K27 (histone 3 lysine residue 27) brings about a region of active chromatin allowing access to transcription activity while its trimethylation will cause silencing of the associated gene at that particular area (no expression of that gene)

Savatey [412]

Answer:

The correct matching pairs are:

1) - B)

2)- E)

3) - A)

4) - F)

Explanation:

Transferases (B): Transeferases is the class of enzyme that catalyzes reactions involving the transfer of certain functional groups. (1)

Example: Transaminase transfers nitrogenous groups

Isomerases (E): Isomerases is the class of enzyme that catalyzes isomerization reactions and intramolecular rearrangements. (2)

Example: Triosephosphate isomerase interconverts aldoses and ketoses

Oxidoreductases (A): Oxidoreductases is a class of enzyme that catalyzes redox reactions (3) which involves the simultaneous transfer of electron.

Example: Alcohol oxidoreductases acts on the alcohol functional group

Ligases (F): Ligases is a class of enzyme that catalyzes reactions involving chemical bond formation between two molecules. (4)

Example: DNA ligase joins DNA fragments
