Distinguish between mitosis and cytokinesis.
murzikaleks [220]

Answer:

mitosis: It is a process by which the duplicated genome in cell is separated into halves that are in nature.

It occur in three phases: interphases, karyokines and cytokinesis.

Cytokinesis: It is a process where the cytoplasm of cell divided two "daughter" cells.

It occur through two processes: in animals, in eukaryotic cell and one in plant cell.

What happens during the initiation step of DNA transcription? A ribosome attaches to the initiation codon of a completed mRNA st
Amanda [17]

Answer:

<u>A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.</u>

Explanation:

Transcription is the process in which DNA template is used to synthesize  mRNA.

There are three steps of transcription:

  • <u>Initiation</u>

It is the process in  which a portion of DNA unwinds and RNA polymerase binds to the promotor region on the DNA.

  • <u>Elongation</u>

It is the process in which RNA polymerase moves along the DNA template and synthesizes mRNA. During this process, unwinding of double stranded DNA takes place.

  • <u>Termination</u>

As the RNA polymerase moves along the DNA template, it finally reaches a termination signal and then stops synthesizing. It is followed by the detachment of the newly formed mRNA and RNA polymerase from the DNA.

<u>QUESTION:</u>

  • <u> A ribosome attaches to the initiation codon of a completed mRNA strand.</u>

This is the incorrect answer choice as this process does not happen in the process of transcription. This event happens<u> in the process of translation in which mRNA is used to synthesize proteins or amino acids. mRNA attaches to ribosome during this process.</u>

  • <u>RNA polymerase moves along the template strand of the DNA creating an mRNA strand.</u>

This is the incorrect answer choice as this event takes place in the process of elongation.

  • <u>A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.</u>

This is the<u> correct answer choice as this event takes place in the process of initiation of transcription</u>

  • <u>The mRNA detaches from the RNA polymerase as the RNA polymerase leaves the DNA strand.</u>

This is the incorrect answer choice. This event takes place in the event of termination of transcription.

Which statement most likely describes the daughter cells produced in the diagram
Juliette [100K]

Answer:

The daughter cells will each produce offspring that will have the same genetic information as the original cell.

Explanation:

The diagram you were given is shown in the image attached below. The options you were given are the following:

  • The daughter cells will pass on only half of the genetic information they received from the original cell.
  • The daughter cells will each produce offspring that will have the same genetic information as the original cell.
  • The daughter cells will each undergo the same mutations as the original cell after reproduction has occurred.
  • The daughter cells will not pass on any of the genes that they received from the original cell.

The diagram shows what cell division looks like. Cell division is the process in which we get two daughter cells from one parent cell. When a cell divides, everything in it divides as well. This is how daughter cells end up with the same structure (e.g. same organelles) as their parent cell.

The daughter cells have the same genetic information as their parent cell. This means that the cells produced by these daughter cells will have the same genetic information as the original parent cell.
