During meiosis I, ____________ chromosomes line up side by side and may shuffle genetic material between themselves.
lozanna [386]

During meiosis I, homologous chromosomes line up side by side and may shuffle genetic material between themselves.

<h3>What is Meiosis?</h3>
  • In sexually reproducing organisms, meiosis is a unique type of cell division of germ cells that results in the production of gametes, such as sperm or egg cells.
  • Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome.
  • Prophase I, Metaphase I, Anaphase I, and Telophase I are the four phases that make up Meiosis I.
  • It deactivates the sporophytic information while activating the genetic information for the production of sex cells.
  • By halving the same, it keeps the chromosomal count constant.
<h3>What is chromosome?</h3>
  • A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code.
  • Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule.

The domestic cat genome contains 2.9×109 base pairs. The length of linker DNA in mammals is 50 base pairs. Approximately how man
IgorLugansk [536]

Answer:

Number of nucleosomes in 2.9 * 10^9bp is equal to 1.47 * 10^7

Explanation:

For wounding one nucleosome, total length of DNA required is equal to 146 bp

The length of  linker DNA in mammals is equal to 50 bp

Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length

= 146 + 50\\= 196bp

Thus, in 196bp length of DNA, the total number of nucleosomes is equal to 1

Thus, number of nucleosomes in 2.9 * 10^9bp is equal to

\frac{2.9* 10^9}{196} \\1.47 * 10^7

Why does the sodium potassium pump require ATP?
SpyIntel [72]

Answer:

The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.
