Answer:
The correct answer is option d. "A region of DNA sequence upstream of a gene where transcription factors bind".
Explanation:
Cis-regulatory elements (CREs) are fragments of DNA that do not encode to a protein, but regulate the transcription of nearby genes. CREs regulation is based on binding to transcription factors. These elements are vital for the regulation of complex molecular mechanisms that involve the participation of multiple genes. Additionally, CREs could participate in pleiotropy (a single gene being responsible for the development of multiple traits), because a single transcription factor could bind to different CREs.

Meiosis is a form of the mobile department in sexually reproducing organisms that reduces the number of chromosomes in gametes (the intercourse cells, or egg and sperm).
Meiosis is responsible for the formation of sex cells or gametes which are chargeable for sexual reproduction. It turns on the genetic information for the improvement of intercourse cells and deactivates the sporophytic information.
Seeing that cellular division takes place twice at some point of meiosis, one beginning cellular can produce <u>4 gametes</u> (eggs or sperm). In every spherical division, cells go through 4 ranges: prophase, metaphase, anaphase, and telophase.
