Repressors are transcription factors that bind to _____________sequences in dna
Trava [24]

Answer:

The given blank can be filled with operator.

Explanation:

The proteins that assist in turning on or turning off the function of a specific gene by getting combined with certain sections of the DNA are known as transcription factors. The transcription factors that activate the transcription of a specific gene are known as activators, while that prevents transcription and is termed as repressors.  

A repressor can be an RNA or a DNA binding protein, which prevents the articulation of genes by getting combined with the operator. A repressor, which binds with DNA prevents RNA polymerase from getting combined with the promoter, which further inhibits the transcription of the genes into mRNA.

Recent photographs of the planet Mars reveal deposits that suggest the former presence of liquid water. How does this compare wi
kolezko [41]

Answer with Explanation:

Let's start first with water on the Earth's moon. This is called "lunar water."

The moon was thought to be barren by scientists long time ago. However, they found out that there are actually <em>water reserves located in the shadowed craters.</em> It is said that the formation of this water was possible with the existence of <u>Oxygen atoms in the lunar rocks and minerals. </u>Due to the <u>solar wind</u> that blew into the place, <u>the Hydrogen ions from the wind combined with the Oxygen in order to form water.</u> So, the water that is found here is relatively fresh.

Let's go to "water on Mars." This is said to be <em>more older than the water on the moon</em> and is actually not that pure for it consists of some mixtures of rocks. It is said that billions of years ago, Mars had an abundant supply of water, but due to climate change, the supply didn't last long. As a result, the planet dried out and only the areas in the polar and mid-latitude regions have water<em> (in the form of ice).</em> This ice melts and refreezes, depending on the temperature. This is an evidence that people may possibly live on Mars.
