A web of proteins in the cytoplasm is known as what?

Biology
1 answer:
Artemon [7]3 years ago
5 0
<span>The cytoskeleton is a structure found in the cytoplasm that is composed of a web of proteins. It is a network composed of protein microfilaments, intermediate filaments, and microtubules. They can be found in all living organisms and are responsible for giving them their distinct cell shapes and coherence. 

Aside from providing the cell shape, the cytoskeleton is also responsible for cell movement, organelle movement, and cell division.</span> <span>It plays a crucial role in cell division because they provide the movement of chromosomes to the daughter nucleus. The absence of these protein filaments would result to different abnormalities and diseases in the genes. </span>

A strand of DNA that is 36 nucleotides long codes for how many amino acids?
Margarita [4]

Answer:

See answer below

Explanation:

Hi there,

Assuming this DNA strand is fully capable of being mature mRNA (5' m7G cap and PolyA tail), nucleotides lead to an mRNA codon, which is 3 nucleotides per codon. In turn, 1 codon leads to 1 amino acid. However, as a single strand, it must be capable of terminating translation, which always requires a stop codon, and thus 3 nucleotides. Hence, we must subtract this from the total amount of codons <em>first</em>.

36 \ ncltd \ \frac{1 \ codon}{3 \ ncltd} = 12 \ codon\\12 \ codon - 1 \ codon \  = 11 \ codon\\11 \ codons\ \frac{1 A.A.}{1 \ codon}  = 11 \ A. A.

Hence, only 11 amino acids will be coded by a single DNA strand 36 ncltd long.

thanks,

The contraction of auricular muscles around the ear produces a range of motions in the ears of domesticated animals as well as t
creativ13 [48]
The correct answer is letter C, in most primates, the inability to move the ear has been replaced by the ability to stand upright on two legs. This is because movement was much of a need to these primates than hunting for food. They needed to be agile to locate specific places where sources of food are abundant.

NemiM [27]

Answer:

The correct answer is - option E.

Explanation:

African infants have had a higher chance of survival if they have a living grandmother who is with no young child of her own, this fact supports the evolution of menopause.

The 2 major hypothesis related to the evolution of menopause explains either to help the mother of the infant, protecting from the risk related to age-specific mortality or to provide maternal grandmothers who enhance their inclusive fitness.

Thus, the correct answer is - option E.

Given the inefficiency of two of the pathways shown in figure 9-4, what advantage could there be to using these pathways to prod
Olin [163]

Answer:

<u>Pathway A and B</u> are <u>anaerobic</u> ways of extracting energy (ATP) from glucose. These pathways are advantageous when little or no oxygen present. The net energy in both pathways is 2ATP. Both pathywas take place in the cytosol of the cell and are categorized as fermentation.

<u>Pathway C is aerobic</u> in which oxygen is used to yield energy (ATP). This pathway is advantageous when energy needs are high because it produces 36 molecules of ATP. Therefore, net energy in this pathway is higher than the anaerobic pathways. This pathyway takes place within the mitochondria and is recognized as cellular respiration.

A schematic illustration can be seen in the image attached.

PS: <u>Glycolysis</u> is common to fermentation and aerobic respiration.

Elza [17]

Answer;

-Endoplasmic reticulum

Explanation;

Molecules produced in the nucleus are transported to the cytoplasm via endoplasmic reticulum.

-Endoplasmic reticulum (ER) is a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins.

It is an interconnected network of flattened sacs or tubes encased in membranes. These membranes are continuous, joining with the outer membrane of the nuclear membrane. It works closely with the Golgi apparatus, ribosomes, mRNA, and tRNA.
