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.

Answer:
The answer is (A. A cladogram.)
Amoeba, paramecia, and euglenas
Answer:
5ʹ-ATTCCGGATCGA-3ʹ
Explanation:
In a double-stranded DNA, two strands are held together with the help of hydrogen bonds between nitrogenous bases and the two strands are anti-parallel, means one strands runs in 5' to 3' direction, while another strand runs in 3' to 5' direction.
According to complementary base pairing rule, adenine makes bonds with thymine and thymine makes bond with adenine; similarly, guanine makes bonds with cytosine and cytosine makes bonds with guanine.
Thus, the complementary base pairing rule, complementary sequence for given DNA sequence would be:
5ʹ-TCGATCCGGAAT-3ʹ
3ʹ-AGCTAGGCCTTA-5ʹ, which can be also written as
5ʹ-ATTCCGGATCGA-3ʹ.
Thus, the correct answer is 'second option.'
