Answer:
Explanation:
The molecular and cellular mechanisms and processes that explain muscle contraction in striated muscle occur in the myofibril sarcomere. Their understanding depends on the organization's understanding of the structure of the sarcomere. In an imaginary experiment we first assemble an ideal sarcomere.
Remember that the myofibril is a set of cylindrical compartments that are located next to each other, constituting an elongated cylinder. Each of these cylinders is a sarcomere and borders its neighbor on a line or band called, line or band z.
On each side of the z line, thin cylindrical filaments that are actin filaments are inserted. Each actin filament is formed by a double strand of actin molecules that are rolled over each other. In this organization, actin is called actin F.
Answer:
This question is asking to fill in the blank spaces with the correct terms. The correct terms to the four blank spaces are:
1) GEL
2) DYE
3) DNA MARKER
4) LID
Explanation:
This question is describing the Gel electrophoresis technique which is used to separate DNA fragments using electric current. The DNA fragments of different sizes migrate through a GEL which serves as the matrix made from Agarose.
In order to physically see the samples that we put in the gel, we first have to add DYE to each sample of DNA. After loading the samples to be separated, a substance made up of DNA fragments of known sizes referred to as DNA MARKER, which acts as the standard curve in a tube is used.
Before running the gel, it's important to make sure that there is LID covering the gel in the gel rig. This will make sure that the electrical current runs through the gel and the gel stays cool.
