All DNA is a cell is harbored in the nucleus, so DNA replication should only occur in the nucleus of the cell.
"Gravitational attraction" is initially responsible for the formation of the clumps of matter within this interstellar cloud.
<u>Answer:</u> Option C
<u>Explanation:</u>
About 4.6 billion years ago, the solar systems were a bunch of gases and dusts, referred to solar nebula. Gravity squeezed the material as it started to rotate, creating the sun at the middle of the fog.
The rest of the material began to accumulate with the sunrise. The smaller particles moved together to form larger particles that were connected by gravity. As lumps develop, gravity increases and turns into kinetic energy of moving particles that collide and produce heat.
In a normal human karyotype, depending on the part of mitosis the cell is in, there are either 23 or 46.
They take over the photosynthetic process for the plant.
