Chromosomes physically exchanging DNA, the formation of a chiasma. Is called what?

Biology
1 answer:
lesantik [10]3 years ago
4 0

Answer:

At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis. In meiosis, absence of a chiasma generally results in improper chromosomal segregation and aneuploidy.

Why are red blood cells unable to replace damaged proteins
Rainbow [258]

The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as the nucleus, ribosomes, and mitochondria which are crucial for protein synthesis, assembly, and repair. In other words, they lack both the information and the machinery for making or repair of proteins.

Due to lack of DNA and cell organelles, red blood cells cannot be able to satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.

DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm,  then translating or decoding this information, which results in the making of protein.

Musculo que tiene las características tanto de musculo esquelético como de musculo liso. Se encuentra en el corazón y sus contra
Andrei [34K]

Answer:

músculo cardíaco

Explanation:

Los 3 tipos de tejido muscular son 1-músculo cardíaco o miocardio (involuntario), 2-músculo liso (involuntario) y 3-músculo esquelético (voluntario). Las células del músculo cardíaco, las cuales son conocidas como 'miocardiocitos', poseen una apariencia estriada y forman la pared del corazón. Los miocardiocitos son alargados, ramificados, y poseen un núcleo central (son células uninucleadas, a diferencia de las células del músculo esquelético, las cuales son multinucleadas). Además, los micardicitos son más cortos (80 a 100 µm) y más anchos (aprox. 15 µm) que las células del músculo esquelético. Los miocardiocitos presentan uniones especializadas conocidas como discos intercalares, los cuales son un tipo de complejo de unión entre los límites de dos cardiomiocitos. En el citoplasma de los cardiomiocitos se encuentran las miofibrillas, las cuales son estructuras contráctililes que les confieren a las células musculares sus propiedades características de contracción y de elasticidad. En estas células (cardiomiocitos) las miofibrillas se disponen de manera longitudininal con un patrón estriado.

Which of the following is not a way in which humans rely on prokaryotes?
Sladkaya [172]
Since there are no written choices, I could guess that prokaryotes are not reliable when it comes to diseases and other forms of ill-causing behavior of these microorganisms.

Scientists rely on prokaryotes to examine their structure and functions in order to come up with a good medicine. Some rely on prokaryotes to do the natural processes of decomposing and recycling matter throughout the earth's spheres.
