Tanzania [10]2 years ago
6 0

The 3 checkpoints include G1 where the cell growth is checked, G2 where the integrity of the DNA/chromosome is checked, and M where the integrity of the metaphase plate is checked.

<h3>Cell cycle checkpoints</h3>

There are 3 regulatory checkpoints in the life cycle of cells:

  • G1: the size of the cell, the presence of growth factors, and the integrity of the DNA are checked before the cell irreversibly commits to division.
  • G2: the integrity of the DNA and the correctness of the replication process at the S-phase are checked.
  • M: correct attachment of the spindle fibers to the chromosomes at the metaphase plate is checked.

Which is used as evidence for the idea that multicellular organisms evolved from prokaryotes
anzhelika [568]

Living things has emerged into three domains called Archaea, bacteria, and eukaryotes. Evident that support the idea that multi cellular that is eukaryotic cell evolved from the prokaryotic cell are the descendents of the separate prokaryotic cells that together form a union which are inter dependent.

For example: The mitochondria which is referred to the energy source of the cell is considered as the great-great-great-granddaughter of a bacterium cell which is free living. This free living bacterium bacterial cell was consumed by an other cell and this remained as the stable guest in the cell. This mitochondria provided chemical energy to the cell and also protected the nutrient rich environment.  which surrounds it. This process of one organism residing in the other organism completely is called endosymbiosis.

The initiation of transcription requires melting of the DNA double helix, i.e. separating hydrogen-bonded base pairs, immediatel
sertanlavr [38]

Answer:

The correct answer is B. DNA helicase first unwinds the double helix around the +1 site.

Explanation:

The helicase is an enzyme that specifically breaks the hydrogen bonds of the bases in the transcription process. As E. Coli is a prokaryote, then, the transcription only occurs in one point of the circular DNA. The promoter region indicates where the DNA polymerase has to start replicating and the Topoisomerase unwinds the parts of the DNA that are being excessively twisted because of the separation of the two strands.
