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.

nydimaria [60]
If tall plants crossed with short plants give all tall, it means that the tall plants contain genes that dominate over the short ones. 
We call the genes for tallness dominant.

Hypothesize how the properties of water protect the aquatic organisms living in a temperate-
xenn [34]

Answer:

Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.
