RNA polymerase is an enzyme responsible for synthesizing RNA molecules from a DNA template during transcription. It reads the DNA template and catalyzes the formation of RNA by linking together RNA nucleotides in the correct sequence.
To determine the first three nucleotides of the complementary RNA strand, you need to match the DNA bases with their RNA counterparts. In DNA, adenine (A) pairs with uracil (U) in RNA, thymine (T) pairs with adenine (A), cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C). If the first three nucleotides of the DNA strand are, for example, A, T, and C, the complementary RNA strand would have U, A, and G as its first three nucleotides.
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
DNA and RNA both contain in all four nitrogen bases. classified into purines and pyrimidines. DNA and RNA in common have Thymine, cytosine and Guanine as the three nitrogen bases. DNA has adenine and instead of adenine RNA has uracil as the fourth nitrogen base.
The three enzymes involved in DNA transcription are RNA polymerase, helicase, and topoisomerase. RNA polymerase is responsible for synthesizing RNA from a DNA template, helicase unwinds the DNA double helix, and topoisomerase helps to relieve the tension that builds up ahead of the replication fork.

There are three main differences between RNA and DNA: The sugar in RNA is ribose instead of deoxyribose, RNA is generally single-stranded, and RNA contains uracil in place of thymine.
Ribosomal RNA, Transfer RNA, and Messenger RNA
A. rRNA Type of RNA molecule transcribed from a DNA template B. codon Sequence of three nucleotides on a messenger RNA molecule C. tRNA RNA component of ribosomes D. anticodon Connects mRNA codon to an amino acid E.mRNA Sequence of three nucleotides on a transfer RNA molecule
The three bases of RNA and DNA put together are called codons in RNA and triplets in DNA. These sequences of bases encode specific amino acids or signal the end of protein synthesis.
DNA has a deoxyribose sugar; RNA has a ribose sugar DNA is a double stranded helix; RNA is a single stranded helix RNA has the nitrogen base uracil instead of thymine (thymine is one of the four bases in DNA).
In DNA, three bases in a row are known as triplets. In RNA, they are known as codons.
The three main structural differences between DNA and RNA are: DNA is double-stranded, while RNA is single-stranded. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the base thymine, while RNA contains the base uracil instead.
RNA is single-stranded, while DNA is double-stranded. RNA contains ribose sugar in its backbone, while DNA contains deoxyribose sugar. RNA uses uracil as one of its nitrogenous bases, while DNA uses thymine.
Transcription is the process of forming RNA from DNA. During transcription, enzymes read one strand of the DNA double helix and synthesize a complementary RNA molecule. This RNA molecule then undergoes processing and modification to become mature RNA.
All three types of RNA (mRNA, tRNA, and rRNA) are made on the DNA template during transcription in the cell's nucleus. This process involves the copying of the DNA sequence into a complementary RNA sequence by RNA polymerase. Each type of RNA serves a specific role in protein synthesis within the cell.
Both DNA and RNA have all three.
