<span>The metabolic activity of a specific region of the living rat brain can be revealed by measurement of Fos protein concentration.
c-Fos is a proto-oncogene that is the homolog of the retroviral oncogene v-fos. It was first discovered in rat fibroblasts as the transforming gene of the FBJ MSV.</span>
Phospholipids. Phospholipids, arranged in a bilayer, make up the basic fabric of the plasma membrane. They are well-suited for this role because they are amphipathic, meaning that they have both hydrophilic and hydrophobic regions. Chemical structure of a phospholipid, showing the hydrophilic head and hydrophobic tails ..
Answer:
It will shrink because it was placed in a hyper tonic solution
Explanation: Hyper tonic = More solute (sugar)
Hypo tonic = more liquid (water)
When a cell is placed in a solution it will essentially try to balance out so in this case water goes out the cell and solute goes, in shrinking the cell.
Answer:
Streptomycin and Erythromycine.
<u>Streptomycin:</u> inhibit protein synthesis by combining irreversibly with 30s subunit mRNA.Thus the normal synthetic sequences is disrupted.
Streptomycin does not stop protein synthesis in eukaryotic cells because it does not bind to eukaryotic ribosomes.
<u>Erythromycine:T</u>he Erythromycine inhibits protein synthesis through interference with the binding 50s subunit ribosome.
Erythromycin does not estop protien synthesis in eukaryotic cells because it does not binds to eukaryotic ribosome.Specificity towards prokaryotes relies upon the absence of 50S ribosomes in eukaryotes.
Antibiotics block processes that occur in prokaryotic cells but not in eukaryotic cells that's why they not affect ekaryotes.
Explanation:
Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors.
Antibiotics block processes that occur in prokaryotic cells but not in eukaryotic cells that's why they not affect eukaryotes.
There are different classes of antibiotics inhibit different steps of prokaryotic life cycle.
<u>Streptomycin and Erythromycin </u>are group of antibiotics that inhibit protein synthesis of bacteria.They are specifically effective against prokaryotes does not inhibit protien synthesis of eukaryotes.
