Name the protein which fills the cells of the stratum corneum and gives the skin its strength.

1 answer:

4 0

Keratin is an intracellular fibrous protein that gives hair, nails, and skin their hardness, strength, and water-resistant properties. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from the deeper layers

Hope this helped!

Good luck :p

<h2>Messenger RNA</h2>

Explanation:

Messenger RNA (mRNA) is a solitary stranded RNA atom that relates to the hereditary arrangement of a quality and is read by the ribosome during the time spent creating a protein
The three most significant strides of pre-mRNA processing are the expansion of settling and <em>signaling factors at the 5′ and 3′ ends of the molecule,</em> and the expulsion of mediating arrangements that don't indicate the <em>proper amino acids. </em>the mRNA <em>transcript can be “edited”</em> after it is transcribed.
During transcription the RNA polymerase read the layout DNA strand the <em>3′→5′ way, however the mRNA is shaped in the 5′ to 3′ direction. </em>
The essential capacity of mRNA is to go about as a intermediary between the <em>hereditary data in DNA</em> and the amino acid sequence of proteins.

An experiment was performed to study the progress of cells through the mitotic cell cycle. The compounds listed below were used

Hatshy [7]

<h2>Mitotic Cell Cycle</h2>

Explanation:

a. Cytochalasin: an inhibitor of actin microfilament

Cytokinesis is the process by which cytoplasm is divided into two cells hence generation of two daughter cells
In animal cells the division of cytoplasm starts with the assembly of contractile ring
Contractile band consists of actin and myosin and catalyze cleavage furrow formation
Cytochalasin is a drug that blocks the polymerization of actin filament
When cytochalasin is added dividing cell fails to undergo in cytokinesis due to defective assembly of contractile band

b. Colchicine: an inhibitor of microtubule formation

Colchicine tightly binds with free tubulin dimer and prevents its polymerization
In this case mitotic spindle apparatus do not assemble and cells unable to do partitioning of chromosomes into two groups
Thus cell division is arrested

c. Aphidicolin: an inhibitor of DNA Polymerase activity

Aphidicolin is used to induce cell cycle arrest via specific inhibition of DNA Polymerase α
It blocks the cell cycle at early synthesis(S) phase

d. Emetine: an inhibitor of ribosome activity

It blocks the protein synthesis in eukaryotic cells by binding to small subunit(40 S) of ribosomes
It interferes with the synthesis and activities of DNA and RNA
