Cytoskeletal elements play important roles in cell division. The mitotic spindle apparatus is made of ________ and pulls sister
Veseljchak [2.6K]

Answer:

Cytoskeletal elements play important roles in cell division. The mitotic spindle apparatus is made of "microtubules" and pulls sister chromatids apart, whereas the contractile ring is made of "actin filaments" and required for the separation of daughter cells at the end of the mitotic phase of the cell cycle.

Explanation:

The three chief organizational apparatuses of the cytoskeleton are microtubules (formed by tubulins), microfilaments (formed by actins) and intermediate filaments. All three apparatuses cooperate with each other non-covalently. The cytoskeleton is composed of protein filaments and is found throughout the inside of a eukaryotic cell. The cytosol is the main component of the cytoplasm, the fluid that fills the inside of the cell. The cytoplasm is everything in the cell except for the cytoskeleton and membrane-bound organelles.

3. a recently developed test for detecting fetal duchenne's muscular dystrophy is ________.
yuradex [85]

Amniocentesis is a freshly established test for identifying fetal duchenne's muscular dystrophy.

<h3>What is tested for during an amniocentesis?</h3>

Amniocentesis is a test that may be recommended to you during pregnancy to determine whether your unborn child has a chromosomal or genetic disorder like Down syndrome, Edwards syndrome, or Patau's syndrome.

<h3>What exactly does an amniocentesis entail?</h3>

A little sample of amniotic fluid is removed during an amniocentesis operation for testing. This is the fluid that a pregnant woman's fetus is enclosed in. The amniotic fluid shields the fetus from harm and is transparent and pale yellow in color. provides infection protection.

<h3>What takes place after a positive amniocentesis test?</h3>

If the test yields a positive result, the fetus may have the genetic disorder. To confirm this, more testing are sometimes required.

Darwin’s theory of common descent states that all organisms _____.
choli [55]
The correct answer would be the last one: "evolved from past organisms." This theory basically just states that all living organisms evolved from a single common ancestor. Hope this helped! :)

What is the major difference in the production of transgenic bacteria, plants, and animals?
Flauer [41]

Answer:

Transgenic animals require a host to grow but transgenic bacteria and plants do not require host.

Explanation:

Transgenic organisms are the organisms in which foreign genetic material are introduced so that the transgenic organism can get some particular traits and characteristic.

The process of producing transgenic animals is different from producing transgenic plant and transgenic animals because in transgenic animals DNA from a cell is transferred into an enucleated oocyte.  

Then this oocyte is transferred to the oviduct of a surrogate mother to raise the genetically modifies embryo but in plant and microbe, no host is required.
