Explanation:
Phage are viruses that must infect bacteria to reproduce. Viral genomes do not contain all the genes needed to produce all proteins necessary for DNA replication, RNA transcription, and protein translation; instead the viruses force bacterial proteins and enzymes to express phage genes instead of bacterial genes.
Phage are very adaptable, and their behavior depends on whether conditions are favorable or unfavorable for making more phage.
When bacteria are plentiful (favorable conditions), viral DNA within the bacteria remains separate from the bacterial chromosome, and the virus forces the bacteria to make more virus. When the amount of virus becomes too much for the cell to hold, the membrane ruptures, and viruses are released to infect surrounding bacteria. This is known as the lytic cycle.
When bacteria are scarce (unfavorable conditions), the viral DNA within the bacteria becomes integrated into the bacterial chromosome. The bacteria survive and are still able to reproduce; viral DNA is transmitted to daughter cells when the bacteria reproduces. This is known as the lysogenic cycle.
As you just read, phage depend on bacteria to reproduce. Phage can be maintained by infecting a culture of bacteria with a strain of phage, and then plating the bacteria on an agar plate to grow.
Suppose that you isolate two mutant strains of phage - one strain cannot enter the lytic cycle and the other strain cannot enter the lysogenic cycle. You also grow wild-type phage as a control. You see three different phenotypes:
A plate with no missing bacteria- the lawn of bacteria is intact
A plate with spots/circles (called plaques) where there are absolutely no bacteria in the circles
A plate with spots/circles (called plaques) where there are some bacteria in the center of the circles.
Based on what you know about what happens in each cycle, match the plating results with the identity of the strain.
Drag each plate into the correct category.
Answers
Answer:
A plate with no missing bacteria- the lawn of bacteria is intact----strain with lysogenic cycle.
A plate with spots/circles (called plaques) where there are absolutely no bacteria in the circles---- lytic cycle
A plate with spots/circles (called plaques) where there are some bacteria in the center of the circles----- wild type phage.
Explanation:
The strain which cannot enter the lytic cycle having no missing bacteria on the plate because the virus remains inside the bacterial cell while on the other hand, the other strain that cannot enter the lysogenic cycle having no bacteria on the circle due to infection of virus spreads throughout the cells and no bacterial cell remains uninfected. One plate having some bacteria and some space having no bacteria due to virus of wild type that shows both cycles.

Answer:
b. synthesis of many extra secreted proteins.
c. mutation of a factor critical for degradation of proteins in the lysosome
d. mutation of a factor important for protein folding in the ER
The conditions that would activate the unfolded protein response are:
Synthesis of many extra secreted proteins.Mutation of a factor critical for degradation of proteins in the lysosome.Mutation of a factor important for protein folding in the ER. What do you mean by unfolded protein response?The unfolded protein response may be defined as a cellular stress response related to the endoplasmic reticulum stress. It is a mechanism through which the accumulation of misfolded protein is induced.
Unfolded protein response gats are activated when there is any mutation or alteration that takes place in the ER, and sometimes lysosomes. Because these are both organelles that mediate the protein trafficking throughout the cell.
Therefore, the conditions that would activate the unfolded protein response are statements (b), (c), and (d).

. The principal site of protein synthesis in a cell is
a. Endoplasmic reticulum

Ribosomes
b. Nucleus
d. Golgi - Apparatus
a.
Answers
Answer:
b. Nucleus
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells. Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include;
1. Cell membrane : is the wall of the cell and typically controls what leaves and enters the cell.
2. Mitochondria : it provides all the energy required in the cell by transforming energy forms.
3. Lysosomes : they are responsible for absorbing materials and breaking the materials taken in by the cells.
4. Chromosomes : they give sets of instructions for the synthesis of products.
5. Ribosomes : they are involved in the build up of proteins.
6. Endoplasmic Reticulum : this is where the ribosomes perform their tasks.
7. Cytoskeleton : they help to maintain and support the shape of the cells.
8. Vesicles : they ensure proteins are properly transported to the right and exact location.
9. Golgi apparatus : it prepares the protein for export by chemically tagging them.
10. Nucleus : it controls all the activities taking place in the cell and the synthesis of proteins.
Hence, the principal site of protein synthesis in a cell is nucleus.

- Phosphate groups of the phospholipid bilayer allow the ions to cross.
- The fatty acid tails of the phospholipids allow the ions to cross.
- Protein channels in the plasma membrane allow the ions to cross.
- Carbohydrate groups on the membrane allow the ions to cross.
Answers
Answer:
Protein channels in the plasma membrane allow the ions to cross.
Protein channels which are present in the plasma membrane of the cell allow the ions to cross the plasma membrane. Thus, the correct option is C.
What are Protein channels?
Channel protein is a kind of protein which is found embedded in the plasma membrane of the cell. Channel proteins function similar to a pore and it allows the diffusion of small ions and water molecules through them. Channel proteins are lipoproteins and these are synthesized in the rough endoplasmic reticulum of the cell near the nucleus.
Ion channels are the transmembrane proteins whose canonical function is the transport of ions and molecules across the plasma membrane to regulate cell membrane potential and also play an essential role in neural communication, nerve conduction, and muscle contraction in the body.
Therefore, the correct option is C.

Heparin, a highly negatively charged glycosaminoglycan, is used clinically as an anticoagulant. It acts by binding several plasma proteins, including antithrombin III, an inhibitor of blood clotting. The 1:1 binding of heparin to antithrombin III seems to cause a conformational change in the protein that greatly increases its ability to inhibit clotting. What amino acid residues of antithrombin III are likely to interact with heparin
Answers
Answer:
Positively charged amino acids
Explanation:
Heparin is an acid polysaccharide that has a strong negative charge due to the sulfate groups on its glucosamine residues. This negative charge confers to heparin anticoagulant activity. The negatively charged groups in the heparin molecule can interact with positively charged (basic) residues, such as arginine (Arg) and lysine (Lys) of plasma proteins. For example, it has been shown that lysine amino acid residues of antithrombin III may be involved in the binding with heparin.

Changes in amino acid can be very important in the function of a protein.

The effect if any of the mutations on the amino acid chain produces that change is called a "missense mutation," because in this type of mutation, the amino acid gets changed.
What is the significance of the types of mutations?There are many different types of mutations that occur during polypeptide formation, such as those that occur but have no effect on the overall structure and function of the enzyme, proteins, etc.; these are known as "silent mutations," while others result in single amino acid changes and are known as "missense mutations." It has many implications, such as in sickle cell anemia, where a single amino acid change causes a change in the hemoglobin structure.
