As we grow, skin cells and blood cells are constantly dividing but as the get damaged. The body creates new cells
Answer:
Meiosis results in gametes that are used in reproduction.
Explanation:
- <em>The sperm and egg have twice as many chromosomes as the parental cells</em>. INCORRECT. Sperm and eggs are the gametes, and they have only half the number of chromosomes that can be found in the germ cells or somatic cells. Gametes are haploid, n.
- <em>Geneticists use the terms "son" and "daughter" to distinguish between cells resulting from cell division</em>. INCORRECT. The term "daughter cells" is used to refer to the products of cell division. "son cells" is not used at all.
- <em>Meiosis results in gametes that are used in reproduction. </em>CORRECT. Germ cells are the reproductive, diploid cells produced by testes and ovaries. After meiosis, each germ cell produces four haploid cells that are the gametes. Gametes´ destiny is to merge during fecundation, creating a new diploid cell called the zygote. The zygote is a diploid cell that suffers successive mitosis to form the new organism.
- <em>Asexual reproduction requires the production of eggs and sperm. </em>INCORRECT. Only sexual reproduction needs gametes. Cells that reproduce asexually duplicate their genetic material and cytoplasmic content and then divide, producing a new cell identical to its parental. This is the case of binary fission, for example.
Answer:
Enzymes known as DNA polymerases are responsible creating the new strand by a process called elongation. ... DNA polymerase then adds pieces of DNA, called Okazaki fragments, to the strand between primers. This process of replication is discontinuous as the newly created fragments are disjointed.
