Energised forms of monomers (or building blocks) used to make a polymer. For example ATP is an activated precursor used in RNA synthesis.
A coding region of a eukaryotic gene. Exons, which are expressed, are separated from each other by introns.
The whole process of transcription and translation
A noncoding, intervening sequence within a eukaryotic gene.
A specific nucleotide sequence in DNA that binds RNA polymerase and indicates where to start transcribing RNA.
An enzyme that links together the growing chain of ribonucleotides during transcription.
A spliceosome is a large and complex molecular machine found primarily within the splicing speckles of the cell nucleus of eukaryotic cells. The spliceosome is assembled from snRNAs and protein complexes. The spliceosome removes introns from a transcribed pre-mRNA, a kind of primary transcript.
The most sophisticated type of RNA processing, known as splicing, occurs during the processing of eukaryotic mRNAs. Splicing occurs in RNA, NOT proteins, genes and/or DNA.
The DNA strand that provides the template for ordering the sequence of nucleotides in an RNA transcript.
The synthesis of RNA on a DNA template.
The synthesis of a polypeptide using the genetic information encoded in an mRNA molecule. There is a change of "language" from nucleotides to amino acids.
