Explain how mitochondria can provide a genetic inheritance derived only from the mother.
Mitochondria contain their own DNA that is inherited independently of nuclear DNA. From which parent did you inherit your mitochondrial DNA?
Mitochondria contain their own genetic material. Mitochondrialmutations are inherited from mother to child, without anycontribution from the father. Why?

- What is mitochondrial DNA and how is it inherited?arrow_forwardWhat is a mitochondrialarrow_forwardThe continuity of life depends on a cell cycle during which genetic information is passed from a parent cell to daughter cells. Because cell division plays several important roles in life, it is important that the cycle be regulated. Which of the following are reasons the cell cycle must be regulated? Select all that apply. The continuity of life depends on a cell cycle during which genetic information is passed from a parent cell to daughter cells. Because cell division plays several important roles in life, it is important that the cycle be regulated.Which of the following are reasons the cell cycle must be regulated? Select all that apply.[ ]To make sure cells only divide when conditions are favorable for growth and development of the organism[ ]To make sure daughter cells end up with the right number of chromosomes[ ]To make sure daughter cells are genetically different from the parent cell[ ]To allow cells to respond to cues from their internal state and from their environment.arrow_forward
- Human cells normally have 46 chromosomes. For each of the following stages, state the number of chromosomes and the number of DNA molecules found in these chromosomes that are present in a human cell. a) Metaphase of mitosis Metaphase I of meiosis c) Telophase of mitosis (after cytokinesis)arrow_forwardThe somatic cell of a sheep contains 54 chromosomes54 chromosomes (2?=54).(2n=54). How many chromosomes and how many DNA molecules would the primary oocyte of this sheep have? chromosomes: DNA molecules:arrow_forwardWhich of the following statements are true regarding mitosis in humans? 23 pairs of homologous chromosomes are separated four haploid gametes are produced in males 46 pairs of homologous chromosomes are separated two genetically identical daughter cells are produced 23 pairs of sister chromatids are separated 46pairs of sister chromatids are separated 1 haploid gamete and 2 polar bodies are produced in femalesarrow_forward
- which stage of the cell cycle do cells spend most of their time in? Explain why you think this is. Explain why mitosis is important to both unicellular and multicellular organisms. discuss how a carcinogen causes mutations that could cause the body to lose control over mitotic events and apoptosis (cell death). What can we do to protect ourselves from the harmful effects of carcinogens?arrow_forwardOrganelle heredity can be attributed to: a. mitochondria and chloroplasts have DNA that is subject to mutation b. mitochondria and chloroplasts lack DNA and are therefore dependent on the maternal cytoplasmic contributions c. organelles such as mitochondria are always dominant d. chloroplasts, for example, are completely dependent on the nuclear genome for componentsarrow_forwardIn which of the three phases of interphase and the stages of mitosis dochromosomes exist as single DNA molecules?arrow_forward
- List at least 4 ways by which mitosis differ from meiosis?arrow_forwardCan mitochondrial DNA be inherited from father?arrow_forwardDoes resulting daughter cells in mitosis and meiosis will have identical features with their parent cell? yes or no? Why? Does Interphase prepare the parent cell for division by means of cell growth and synthesis? yes or no? Why? Does the number of chromosomes found in the daughter cells after mitosis and meiosis will be the same as that of the parent cell? yes or no? Why?arrow_forward
