To choose the strand the promoter acts to aim the RNA polymerase.
<h3>
What does RNA polymerase do?</h3>
RNA polymerase synthesizes RNA by following a strand of DNA. The primary transcription enzyme is RNA polymerase. When RNA polymerase connects to a promoter sequence near the start of a gene, transcription starts (directly or through helper proteins). To create a fresh, complementary RNA molecule, RNA polymerase employs one of the DNA strands (the template strand) as a template.
Three distinct RNA polymerases (RNAPs), which transcribe various kinds of genes, are present in all eukaryotes. RNA polymerase I transcribe rRNA genes, RNA polymerase II transcribes mRNA, miRNA, snRNA, and snoRNA genes, and RNA polymerase III transcribes tRNA and 5S rRNA genes.

A forest fire would burn large trees, fertilizing the soil and makes room for smaller plants to grow, which provides more food for herbivores. The lack of trees also makes it easier for carnivores to hunt prey. Good luck in high school!
Answer:
Cartilage rings of trachea have protective role
Explanation:
Trachea is a tube, part of the respiratory system, which allows the passage of the air: from larynx to lungs (primary bronchi). It is enveloped with cartilage rings that prevent collapse of the trachea when there is no air. The cartilage "rings" are C-shaped, except one full ring-shaped - the cricoid cartilage which attaches trachea to the larynx.
Answer:
colorblindness
Explanation:
Colorblindness is a recessive sex-linked trait. ... Remember that in incomplete dominance, the two traits blend together; in co-dominance, the two traits are equally expressed; and in sex-linked traits, the traits can be dominant or recessive, but they always appear on the X-chromosome.
