The release of an inorganic phosphate from the myosin molecule directly results in ________

zhuklara [117]

Answer:

power stroke

Explanation:

The process of muscle contraction requires several steps.
The most famous theory on how the contraction and relaxation of muscles take place is the sliding filament theory.
However, this theory has been refined and one important addition to it is the mechanism by which myosin can pull actin and cause shortening of the sarcomere.
For the movement of myosin, it binds and releases actin and forms cross bridges.
Myosin is subdivided into two regions - S1 and S2. The contraction of the S1 region is what constitutes the power stroke.
An important requirement of the power stroke is the hydrolysis of ATP to release an inorganic phosphate which provides energy for the process.

What is the best explanation if the gel of your PCR product shows smeared bands of multiple sizes? Select one:

trapecia [35]

Answer:

e. None of the above

Explanation:

For me as a Researcher, the reason could be increased Concentration of your DNA sample which you are using as your template. Try to decrease the concentration of DNA (up to 100 ng per reaction is enough and can increase up to 200 ng). so the reason for getting non specific bands is increase concentration of DNA which results in non specific amplification and also degradation of DNA in the reaction which you can see in your gel electrophoresis results.

i always corrected my results using the same technique that is lowering the concentration of DNA between 100 and 200 ng per single reaction of PCR.

Amino acids with hydrophobic r groups are most often found buried in the interior of folded proteins. true or false

pentagon [3]

Answer:

True

Explanation:

Hydrophobicity is the aversion to the water of a molecule (or part of it). Amino acids with a hydrophobic R group (glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, and tryptophan) <em>will fold with the R groups in the interior to avoid water. This behavior is one of the most important forces in protein folding. </em>You can see it exemplified in the image I added.

I hope you fidn this information useful and interesting! Good luck!
