Answer:

The sun, Earth and the moon are aligned, but because the moon's orbit is not exactly in the same plane as Earth's orbit around the sun, they rarely form a perfect line. When they do, we have a lunar eclipse as Earth's shadow crosses the moon's face.

Transcription begins at a promoter. What is a promoter? a. A site in DNA that recruits the RNA Polymeraseb. Part of the RNA mole

arsen [322]

The correct answer is: a. A site in DNA that recruits the RNA Polymerase

Promoters are regions of DNA molecule located near the transcription start codons of genes, usually upstream on the DNA with the function to initiate DNA transcription. Promoters contain specific DNA sequences (e.g. TATA boxes) that are binding sites for the enzyme RNA polymerase and transcription factors that recruit RNA polymerase. Transcription factors can regulate gene expression and act as activators or repressors depending on sequences that attach to specific promoters.
