<span>The right option is <span>B) Combination of all the wavelengths of visible light
</span><span>White light is formed when there is mixture of all the colors of the visible light spectrum (ROYGBIV). White light is perceived when all the wavelengths of the visible light spectrum strike the eye at the same time. The sensation of white is not the result of a single color of light.

Answer:
No, CREs usually don't account for differences in gene expression levels.
Explanation:
<em>Cis</em>-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene <em>transcription</em>. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate <em>gene expression levels</em>.
Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.
