Answer:

Microtubules have several functions. For example, they provide the rigid, organized components of the cytoskeleton that give shape to many cells, and they are major components of cilia and flagella (cellular locomotory projections). They participate in the formation of the spindle during cell division (mitosis).

triplet microtubules are linked together to make the walls of the cylinder.

Answer:

Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility

Centrioles are cylindrical structures that are made up of protein tubes called microtubules. Specifically, nine groups of three microtubules, known as triplet microtubules, are linked together to make the walls of the cylinder.

Some genes are important enough to be called "molecular switch" or "master" genes. What is the purpose of these genes?

trapecia [35]

Answer:

Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).

Explanation:

Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.

The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.

The other options are not correct because:

B. Master genes do not determine the organization of the genome .

C. Regulation of cell metabolism depends of substances as hormones and enzymes.

D. The rate of translation does not depend on the activity of master genes.

3 best methods of determining latitude

Anit [1.1K]

Latitude measures how far a point is north or south of the equator. Since the earth is round, distance from the equator is measured in angular degrees with the equator being 0 degrees and the northernmost point -- the North Pole -- being at 90 degrees. The southernmost point -- the South Pole -- is also at 90 degrees.Latitude is measured in degrees north when in the northern hemisphere and degrees south when in the southern hemisphere.

Hope this helps. :)

The Binding Immunoglobulin Protein (BiP) is a molecular chaperone that is essential for the translocation of secreted peptides i

Evgen [1.6K]

Answer: Protein folding and oligomerization

Explanation:

Binding immunoglobulin protein (BiP) is a vital protein present in humans essential for the translocation of secreted peptides.

BiP is a molecular chaperone which is present in lumen of ER (endoplasmic reticulum) which binds to the new protein and then translocat into the ER. The protein in ER is maintained under subsequent condition and important for protein folding and oligomerization (conversion of a monomer or group of monomer into an oligomer).

Several other functions of BiP are:

ER translocation
ER-associated degradation (ERAD)
UPR pathway

Hence, BiP is a chaperone, it is important for protein folding and oligomerization.
