Which of the following is an accurate description of meiosis?
Which of the following is a correct description of meiosis? – Meiosis is one round of DNA replication followed by one round of cell division. – Meiosis is two rounds of DNA replication followed by two rounds of cell division. … Meiosis is one round of DNA replication followed by two rounds of cell division.
What is the description of meiosis?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. … Meiosis I is a type of cell division unique to germ cells, while meiosis II is similar to mitosis.
Which of the following is an accurate description of the overall purpose of meiosis?
The overall purpose of meiosis is to produce gametes, cells that are involved in sexual reproduction.
Which meiosis is most accurate?
The exchange of genetic material between homologous chromosomes means that a single chromosome now combines genetic information from both parents. Which about meiosis is most accurate? … Meiosis makes it possible for a zygote to have the correct number of chromosomes.
Which statement would be accurate in describing the DNA of a prokaryotic organism?
Which statement below would be accurate in describing the DNA of a prokaryotic organism? The DNA of a prokaryotic cell is contained in a single, circular chromosome about a millimeter in circumference.
Which is the most accurate description of the result of mitosis?
Then in mitosis, the sister chromatids of each chromosome separate, so each daughter cell receives one chromatid from each chromosome. The result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes.
Which is true of meiosis?
Meiosis is a process where a single cell divides twice to produce four daughter cells. These daughter cells are haploid, which means that they contain half the number of chromosomes of the parent cell. They are genetically distinct cells sex cells—sperm in males, eggs in females.
What is the main purpose of meiosis?
Therefore the purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells.
What are the key features of meiosis?
Features of Meiosis
- It results in the formation of four daughter cells in each cycle of cell division.
- The daughter cells are identical to the mother cell in shape and size but different in chromosome number.
- The daughter cells are haploid.
- Recombination and segregation take place in meiosis.
Which of the following statements is accurate when referring to a cell about to begin mitosis quizlet?
Which of the following statements is accurate when referring to a cell about to begin mitosis? Mitotic spindles have reached into the nucleus and have attached to the sister chromatids. Identical sister chromatids have formed and each is a newly replicated DNA double helix.
Which of the following is a correct description for mitosis?
Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
Which of the following accurately describes the actions occurring during the phase entitled G1?
4 Which of the following accurately describes the actions occurring during the phase entitled G1? Each chromosome is duplicated; each chromosome results in two sister chromatids attached at a centromere. The chromosome number is halved in preparation for cell division.
Which description distinguishes the process of meiosis from mitosis?
Which description distinguishes the process of meiosis from mitosis? Unlike mitotic cells, meiotic cells undergo a single division to halve their chromosome number, after which they undergo crossing over to restore their diploid state.
What is meant by the statement that meiosis results in gene segregation?
In essence, the law states that copies of genes separate or segregate so that each gamete receives only one allele. … As chromosomes separate into different gametes during meiosis, the two different alleles for a particular gene also segregate so that each gamete acquires one of the two alleles.
Which statement best describes the outcomes of both meiosis and mitosis?
Which statement best describes the outcomes of both meiosis and mitosis? Cell division results in daughter cells that contain DNA. Each daughter cell has two complete sets of chromosomes. Within a cell, two chromosomes pair up and exchange segments of genetic material.
