The synthesis of RNA on a DNA template.
A type of RNA, syntesized from DAN, that attaches to ribosomes in the cytoplasm and specifies the primary structure of a protein.
An enzyme that links together the growing chain of ribonucleotides during transcription.
The DNA strand that provides the template for ordering the sequence of nucleotides in an RNA transcript.
A specific nucleotide sequence in DNA that binds RNA polymerase and indicates where to start transcribing RNA.
A special sequence of nucleotides in DNA that marks the end of a gene.
A regulartory protein that binds to DNA and stimulates transcription of specific genes.
A promoter DNA sequence crucial in forming the transcription initiating complex.
5' Cap and Poly A Tail
The modified end of the 3' end of an mRNA molecule consisting of the addition of some 50 to 250 adenine nucleotides.
A noncoding, intervening sequence within a eukaryotic gene.
A codin region of a eukaryotic gene.
The most abudant type of RNA, which together with proteins, forms the structure of ribosomes.
A change in a gene at a single nucleotide pair.
The most common type of mutation, a base-pair substitution in which the new codon makes sense in that it still codes for an amino acid.
A mutation that changes an amino acid codon to one of the three stop codons, resulting in a shorter and usually nonfunctional protein.
