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.

Answer:
Bats are the only mammals that can fly, but vampire bats have an even more interesting distinction—they are the only mammals that feed entirely on blood.
Nocturnal Behavior
These notorious bats sleep during the day in total darkness, suspended upside down from the roofs of caves. They typically gather in colonies of about 100 animals, but sometimes live in groups of 1,000 or more. In one year, a 100-bat colony can drink the blood of 25 cows.
During the darkest part of the night, common vampire bats emerge to hunt. Sleeping cattle and horses are their usual victims, but they have been known to feed on people as well. The bats drink their victim's blood for about 30 minutes. They don't remove enough blood to harm their host, but their bites can cause nasty infections and disease.
Hunting for Blood
Vampire bats strike their victims from the ground. They land near their prey and approach it on all fours. The bats have few teeth because of their liquid diet, but those they have are razor sharp. Each bat has a heat sensor on its nose that points it toward a spot where warm blood is flowing just beneath its victim's skin. After putting the bite on an animal, the vampire bat laps up the flowing blood with its tongue. Its saliva prevents the blood from clotting.
Young vampire bats feed not on blood but on milk. They cling tightly to their mothers, even in flight, and consume nothing but her milk for about three months.
The common vampire bat is found in the tropics of Mexico, Central America, and South America.

If a scientist wanted to compare the expression of one gene under two sets of conditions, chain termination is the technique they would use.
Chain termination is any chemical response that ceases the formation of reactive intermediates in a sequence propagation step withinside the route of a polymerization, efficaciously bringing it to a halt.
Sanger sequencing, additionally referred to as the “chain termination technique”, is a way for figuring out the nucleotide collection of DNA. The approach become evolved with the aid of using time Nobel Laureate Frederick Sanger and his colleagues in 1977, subsequently the call the Sanger Sequence.
