Which statement correctly compares the transfer of genetic material during mitosis and meiosis?

Answer:

The statement that compares mitosis and meiosis in relation to the transfer of genetic material is that mitosis divides into two cells with the same genetic material, whereas meiosis divides into four cells with half the genetic material.

Explanation:

Mitosis is the cell division into which a mother cell divides and gives rise to two identical daughter cells. It is a kind of cloning, so the daughter cells have the same number of chromosomes and the same genetic code. Mitosis is composed of the following phases: prophase, metaphase, anaphase and telophase. In meiosis, the mother cell divides into four daughter cells with half of its genetic material and chromosome numbers. Meiosis is composed of meiosis I (prophase I, metaphase I, anaphase I and telophase I) and meiosis II (prophase II, metaphase II, anaphase II and telophase II).

Mitosis is an equational division, as each mother cell produces two genetically identical daughter cells, and meiosis is a reductive division, as each mother cell produces four daughter cells with half the number of chromosomes and genetic material.

Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. i hope that this helps you out, have an amazing day

Match the following.
valkas [14]

Answer:

1 . The stage on the first meiotic division when the homologous chromosomes move to opposite poles but the sister chromatids remain together

: b. Anaphase I

2 . The stage in the second meiotic division where sister chromatids migrate to opposite poles

: c. Anaphase II

3 . A structure on the chromosome that holds a pair of chromatids together during replication

: f. centromere

4 . A double-stranded chromosome following replication attached by a centromere

: d. chromatid

5 . A condition where non-sister chromatid of homologous chromosomes exchange genes

: e. crossing over

6 . The stage in the first meiotic division where the homologous chromosomes line up as a pair

: a. Metaphase I

7 . The stage in the second meiotic division where the chromatid pair lines up at the equator of the cell: g. Metaphase II

Explanation:

DNA replication occurs during the S phase of the interphase of the cell cycle. The replicated DNA molecules are accommodated in two sister chromatids of a chromosome that are held together by a centromere.  

During prophase I, the chromatids of a homologous chromosome pair exchange a genetic segment. This process is called crossing over. It generates recombinant chromatids with new combinations of genes.

Metaphase I of meiosis I includes the alignment of homologous pairs of chromosomes at the cell's equator. This is followed by separation and movement of homologous chromosomes to the opposite poles of the cell during anaphase I.  

Metaphase II of meiosis II includes the alignment of individual chromosomes, each with two sister chromatids, on the cell's equator. During anaphase II, splitting centromere separates the sister chromatids which then move to the opposite poles of the cell.

Nuris is writing a paper on the scientist who first named cells after studying cork under a microscope. Who is her paper about?
Setler79 [48]
Robert Hooke was the first scientist to discover cell. This discovery was made possible by the use of microscope which he invented. With this microscope, Robert examined a cork and noticed pores which filled the entire volume of the thin slices of cork; he called the pores cells. This discovery was made in January 1653.

algol [13]

I believe the answer is Axis III

In psychiatric problem, the doctor could make diagnosis in 5 different axis to make sure they assess the patient comprehensively. Axis III is dedicated for general medical condition. In this case, serious cystic acne and bad skin would be categorized as general medical condition because it was not psychological or personality disorder.
