The letter "u" is used in DNA sequences to represent deoxyuridine, which is a base found in RNA but not in DNA. In RNA sequences, "u" stands for uracil instead of thymine, which is found in DNA sequences.
The region of DNA where RNA synthesis begins is called the promoter region. This region contains specific sequences that serve as binding sites for RNA polymerase, the enzyme responsible for synthesizing RNA. Transcription initiates at the promoter region.
An intervening sequence of DNA that is not expressed is called an intron. Intron sequences are removed during RNA processing, while the remaining expressed sequences are known as exons.
No, a codon does not catalyze RNA synthesis. Codons are sequences of three nucleotides in mRNA that correspond to a specific amino acid during translation. RNA synthesis is carried out by an enzyme called RNA polymerase.
Transfer RNA (tRNA) molecules serve as interpreter molecules that recognize specific amino acids and nucleotide base sequences. tRNA carries the corresponding amino acid to the ribosome during protein synthesis.

Sequences of nitrogenous bases in RNA that do not code for proteins are called non-coding RNAs. These non-coding sequences play various regulatory roles in the cell, such as gene expression regulation and cellular processes modulation.

RNA polymerase attaches and initiates transcription.
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.
called coding sequences or exons. These sequences are transcribed into messenger RNA (mRNA) and eventually translated into a specific sequence of amino acids to form a protein.
The nontranscribed region of DNA to which RNA polymerase binds to initiate transcription is called the promoter region. It contains specific sequences that signal to RNA polymerase where to begin transcribing the gene.
