Answer: Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

QUESTION:
ANSWER:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, like the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains
Meanwhile, as the helicase separates the strands, another enzyme called primase briefly attaches to each strand and assembles a foundation at which replication can begin. This foundation is a short stretch of nucleotides called a primer
After the primer is in place on a single, unwound polynucleotide strand, DNA polymerase wraps itself around that strand, and it attaches new nucleotides to the exposed nitrogenous bases. In this way, the polymerase assembles a new DNA strand on top of the existing one

Select the correct answer. A roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. How much energy does the sandwich provide? A. 747 calories B. 542 calories C. 502 calories D. 367 calories E. 332 calories
Answer:
D. 367
Explanation:
If a roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates, it contains 367 calories of energy, hence option D is correct.
What is food energy?Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.
The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.
To find the total calories, multiply the given biomolecules grams with their calorie count.
= 42 × 4 + 7 × 9 + 34 × 4
= 168 + 63 + 136
= 367 calories
Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.

when are chromosomes (dna) copied?
Answer:
Interphase begins with G1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids.
Have a good day. :)
Answer:
Chromosome replication
Explanation:
Chromosome replication is a key event during the cell cycle that must be completed before a cell divides. To reproduce successfully, every cell must replicate its chromosome and distinguish these sister chromosomes from one another.

the process which takes place in guard cells but not in other epidermal cells is?
Answer:
guard cells chloroplasts , involved in the photosynthesis where epidermal cells are living cells covering the outside surface of the herbaceous plants they contain a thick covering of cutting which reduces the water loss from Plants epidermal cells in roots are specialized for water and ion absorption don't know if it helped but good luck
Photosynthesis
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there.
Difference in guard and epidermal Cells:Two guard cells form a stoma, controlling the gas exchange of the plant by regulating the size of the stoma whereas epidermal cells provide a protection to the plant from the external environment.
Photosynthesis does not take place in epidermal cell because:The epidermal cells that make up this skin are transparent. As most epidermal cells lack chloroplasts, they can't perform photosynthesis, or the use of sunlight to convert carbon dioxide and water into glucose and oxygen.

A. uses electricity
B. specimens cannot be alive
C. lower magnification power
D. more expensive to purchase and operate
Answer:
d
Explanation:
The drawback or disadvantage associated with the use of light microscopes over electron microscope is its lower magnification power.
LIGHT MICROSCOPE:
Light microscope is a type of microscope in which photons of light is used to view specimens. The light microscope is distinct from the electron microscope being that electron microscope uses beam of electrons instead. One advantage of light microscope is that it can view specimens alive while electron microscope can only view dead specimens. However, one disadvantage associated with the use of light microscope is that it possesses a lower magnification compared to electron microscopes.Learn more at: https://brainly.com/question/4442916
