Document Summary
Ribonucleotides - consist of a sugar, a nucleotide base, one or more phosphate groups. Rna synthesized in the nucleus and carries information to the cytoplasm for translation into protein. Mrna - produced by protein producing genes. Telomerase rna - provides a template for synthesis of repetitive dna telomere. Rna polymerase ii - rna is synthesized using dna as a template sequences. The dna coding strand and the mrna transcript have the same polarity and sequence, substituting u in mrna for t in dna. Messenger rna, most snrna splicing, exons are coding regions of a piece of dna. Intron/ exon - intron is a non-coding piece of dna that is usually removed during intron. Isoform - different versions of a protein encoded from the same gene. Cystic fibrosis - when post-translational modifications are disrupted by mutations, there. Cystic fibrosis can be caused by mutations removing splice sites, leading to exon can be severe effects on health removal or intron inclusion.
