Exposure of zebrafish nuclei to meiotic cytosol resulted in phosphorylation of NEP55 and L68 proteins by cyclin-dependent kinase
Tpy6a [65]

Answer: THEY ARE INVOLVED IN THE DISASSEMBLY OF THE NUCLEAR ENVELOPE

Explanation: The disassembly of the nuclear envelope is triggered by the cyclin‐dependent kinase at the onset of mitosis. At this point, Integral nuclear membrane proteins diffuse/move into the endoplasmic reticulum (ER) after nuclear envelope breakdown. The nuclear envelope reassembles around compact chromosome mass at late anaphase/telophase and the chromosomes condenses and become visible.

Anika [276]

A solid minute object that is said to come together for the formation of the planet and are believed to produce cosmic dust are called planetesimal.

The options that best describes the planetesimals are:

  • Option A. They are the origins of planets.

  • Option B. They formed from gas and dust.

  • Option D. They are believed to have developed in debris disks.

The descriptions can be explained as:

  • It is believed that planets formation occurred through planetesimals. The formation happened from gas, dust particles and debris.

  • By the process of accretion, the discs coalesced and became bigger and solid over time. This bigger mass started attracting other matters towards each other because of gravitational force.

  • This pull resulted in either breaking or creation a bigger mass of pieces known as planetesimals. The collision continued to become bigger and solid planets we know today.

Therefore, options A, B and D are correct.
