Answer:
D. Single-stranded
Explanation:
DNA normally has a <em>double-stranded </em>structure. Each strand is composed by nitrogenous bases, sugars and phospates; strongly binded together by chemical bonds. The strands are bonded to each other, however, by relatively <em>weak interactions </em>between the hydrogen atoms in the nitrogenous bases in each strand. The energy supplied by heat is enough to break the weak interactions between hydrogens, but not enough to break the strong chemical bonds that make up the strands.
Answer:
Cytokinesis
Explanation:
I search and I think it is this one see by yourself if I am right so this is the answer.
Image of the cell cycle. Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
The property of creep can be defined as the tendency of a solid material to move or deform slowly under the influence of mechanical stresses. This can occur as a result of long-term exposure to high levels of stress which is below the yield strength of the material.
The water's ability to freeze and thaw is the basic property of water that is partly responsible for creep.
Mutation rate is not a difference between a population showing exponential growth and a population showing logistic growth.
The correct option is (B) Lysine.
The precursors glutamine (N2 and N9), glycine (C4, C5, and N7), aspartate (N1), co2 (C6), and folate are used to create the purine ring (C2 and C8). All are precursors to the purine ring, with the exception of lysine.
How is Purine synthesized de novo?
- In all cells, the cytosol is where purine biosynthesis takes place.
- There are 11 steps that are catalyzed by enzymes that build the purine ring. Each enzyme includes several monomers because it is oligomeric.
- The reaction does not release the intermediate products that are created. They are instead transported to the next enzyme in the process.
- The biosynthesis process in the human body can provide the body's need for purine in metabolic processes. Clinical symptoms might become unpleasant if purine synthesis is inadequate or if biosynthetic routes are aberrant.
