Answer:

A transcription factor

Explanation:

In order for transcription to begin in eukaryotes, not only must RNA polymerase be attached to the double strand of DNA, but several transcription factors must also be binded. Without them the RNA polymerase machinery will not start.

In example GTF's (General transcription factors), also known as basal transcriptional factors, are protein factors that binds into the promoter on DNA to activate transcription. The basic transcriptional apparatus that first bind to the promoter is RNA polymerase + GTFs +a multi-protein complex.

All of the following contributes to turbulent blood flow except A) when there are irregularities in the vessel wall. B) at high
GaryK [48]

All of the following contributes to turbulent blood flow except  third and fourth heart sounds.

<h3><u>Explanation:</u></h3>

The blood flow in human body is always described to be laminar. Some conditions cause the high flow when there is an ascending aorta. This causes the laminar flow of blood into turbulent. When this occurs the flow of the blood will not be smooth and linear.  

When the kinetic energy in the fluid flow increases the turbulent flow of blood occurs. Both the magnitude and the direction of the flow changes in this type of blood flow. These are caused by the irregularities in the vessel walls, flow rates to ne higher and opening of the valves of the heart.
