Cycle Of The Cell - The Science Quiz

Mitosis is a type of cell division that occurs in eukaryotic cells. Its major purpose is to ensure growth and replace worn out or damaged cells in the body. During mitosis, a single cell divides into two identical daughter cells, each containing the same number of chromosomes as the parent cell. This process allows for the growth and development of organisms, as well as the replenishment of cells that have been damaged or have reached the end of their lifespan. Therefore, the statement "The major purpose of mitosis is for growth and to replace worn out cells" is true.

Each chromosome is composed of two sister chromatids, which are replicated copies of the original chromosome. During cell division, the sister chromatids separate and each is distributed to a daughter cell. Therefore, the sister chromatids contain identical genetic information. This is a fundamental process in cell division called chromosome segregation.

The correct answer is interphase. Interphase is the first stage of the cell cycle, where the cell prepares for division by growing in size, replicating its DNA, and performing normal cellular functions. It is a period of intense activity and is divided into three sub-phases: G1 phase, S phase, and G2 phase. During interphase, the cell is not actively dividing but is getting ready for the next stages of the cell cycle, such as mitosis or meiosis.

Mitosis is a type of cell division that results in the formation of two identical daughter cells from a single parent cell. Therefore, the correct answer is "two" new cells.

The "get ready" stage refers to the phase in the cell cycle where the cell prepares for cell division. This stage is known as interphase. Interphase is the longest stage of the cell cycle and consists of three phases: G1 phase, S phase, and G2 phase. During interphase, the cell grows, replicates its DNA, and prepares for cell division. Therefore, interphase is the correct answer as it accurately describes the stage where the cell gets ready for division.

Mitosis is the correct answer because it is a type of cell division in which a single cell divides into two identical daughter cells. During mitosis, the genetic material of the cell is replicated and then evenly distributed between the two daughter cells. This process is crucial for growth, development, and repair in multicellular organisms.

DNA is found in the nucleus, specifically in the form of chromatin. Chromatin is a complex of DNA, proteins, and RNA that makes up the chromosomes. The centromere is a specific region on the chromosome where the sister chromatids are attached, but it does not contain DNA itself. The nucleus is the organelle that houses the DNA and controls the cell's activities. The vacuole is a storage organelle in plant cells and does not contain DNA. Therefore, the correct answer is the chromatin, as it is the form in which DNA is found in the nucleus.

During interphase, the genetic material in a cell doubles through a process called DNA replication. This is necessary for cell division to occur. Interphase is the longest phase of the cell cycle and is divided into three stages: G1, S, and G2. In the S phase, DNA replication takes place, resulting in the formation of two identical copies of the genetic material. Therefore, interphase is the correct answer as it is the only phase where the genetic material doubles.

Interphase is the phase in the cell cycle where the DNA is replicated in preparation for cell division. During this phase, the cell undergoes growth and carries out normal cellular functions. The DNA is duplicated so that each resulting cell will have a complete set of chromosomes. Therefore, interphase is the correct answer as it accurately describes the process of DNA replication and the formation of two identical full sets of chromosomes.

During anaphase, the sister chromatids of each chromosome separate and move towards opposite poles of the cell. This is facilitated by the shortening of microtubules attached to the chromosomes, which pull them apart. Therefore, at each pole of the cell, a full set of chromosomes gather together in anaphase.
