Sample Questions for Unit 2 Test
Here are some sample questions that will help you prepare for the Unit 2 test:
1. Describe the process of mitosis.
Mitosis is a cell division process that results in the formation of two genetically identical daughter cells. It consists of four main stages: prophase, metaphase, anaphase, and telophase. In prophase, the nuclear membrane breaks down, and the chromosomes condense. In metaphase, the chromosomes align at the equator of the cell. In anaphase, the sister chromatids separate and move towards opposite poles of the cell. In telophase, the nuclear membrane reforms, and the chromosomes decondense. Finally, cytokinesis occurs, resulting in the division of the cytoplasm and the formation of two new cells.
2. What is the difference between asexual and sexual reproduction?
Asexual reproduction involves the production of offspring from a single parent without the involvement of gametes. The offspring are genetically identical to the parent and to each other. Examples of asexual reproduction include binary fission in bacteria and mitosis in multicellular organisms. Sexual reproduction, on the other hand, involves the fusion of gametes from two parents to form offspring. This process results in genetic diversity and allows for the combination of traits from different individuals. Examples of sexual reproduction include fertilization in animals and pollination in plants.
3. Explain the role of DNA in heredity.
DNA, or deoxyribonucleic acid, carries the genetic information that determines an organism’s traits. It is composed of nucleotides that are arranged in a double helix structure. DNA is located in the nucleus of eukaryotic cells and in the nucleoid region of prokaryotic cells. During reproduction, DNA is replicated to ensure that each daughter cell receives a complete set of genetic information. Through the process of transcription and translation, DNA is used as a template to produce proteins, which are responsible for the expression of traits. Mutations in DNA can lead to changes in the genetic code and may result in variations in traits.
