Answer:
The correct option is b. G1 phase. When a newly formed cell enters into interphase and begins conducting metabolic functions, it is in <u>G1 phase.</u>
Explanation:
The cell cycle comprises a whole series of events or phases that take place in the cell during its growth and division. A cell spends most of its time at the stage called<em> the interface</em>, and during this time it grows, duplicates its chromosomes and prepares for cell division. The cell cycle has different phases, which are called G1, S, G2 and M.
G1 phase is that in which the cell prepares to divide, during this phase, the cell grows rapidly, while performing routine metabolic processes. It also produces proteins necessary for DNA replication and copies some of its organelles in preparation for cell division. A cell normally spends most of its life in this phase. This phase is also known as Gap 1 phase and actively synthesize RNA and proteins.
G0 phase is a period or cycle of a cell where it remains in a resting state, in this phase mature cells that leave the cell cycle are placed.
G2 phase, during this stage, the cell makes the final preparations for its division.
Answer: That answer is completely FALSE
Explanation:
<span>Protein tertiary structures
are known to be a three dimensional structure of a protein with a single
polypeptide chain (backbone) and one or more protein secondary structures known as
protein domains.</span>
Tertiary Structure Interactions
1) Hydrophobic Interactions: they are non-
covalent bonds and very important in the formation of tertiary structure.
2) Ionic Bonds: the interaction of both positive
and negative amino acids forms a bond that helps to stabilize the protein molecules.
3) Hydrogen Bonds: this bond exit between the
amino acid with hydrophilic side chain found on the surface of the molecules and
water molecules in a solution.
4) Disulfide Bridges: it is a strong covalent bond commonly found between cysteine residues in close proximity space.
Answer:
The specimen are placed in vacuum while examining the cells or living organisms. Also, the electron must penetrate inside of the cell and in such conditions, any living organism is not able to survive. Thus, this reason best explains the answer to why dead cells specimen must be used for Transmission electron microscopy.
