The amount of DNA that is associated with each nucleosome is a approximately 200 bp. This is determined by treating chromatin wwith a certain enzyme that cuts DNA. This enzyme is called DNases. Every chromosome has hundred of thousands of nucleosomes that are joined by DNA strands that pass between them.

<u>Answer:</u>

A nucleosome is a structure that is consists of DNA wrapped around 8 sub-units of a protein namely the histone protein. There are packing of these materials around the proteins decide the transcription site of most of the RNA.

The amount of DNA that is packaged inbetween is about 1.7 turns of the DNA that contains 146 base pairs and about 20 base pairs are in between the turns which sums it to 166 base pairs associated with each nucleosome.

The nurse is performing disability assessment.  

Disability assessment is a component of the primary survey, which is performed to evaluate the consciousness level, which may get affected due to a neurologic injury. In the mnemonic AVPU, the A indicates alert, V indicates a response to voice, P indicates a response to pain, and U indicates unresponsiveness.

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.

k0ka [10]

Answer:

The answer is $8.33 per cubic yard.

Explanation:

This problem is just a normal math equation. You divide the price by how much space you are covering to get the smallest ratio(15 million divided by 1.8 million). After dividing you get the answer of $8.33 per cubic yard.
