messenger RNA (mRNA)
MiRNAs can regulate unique target genes, leading to tumorigenesis and tumour progression. ______ plays an important role not only in regulating genes but also in mediating cellular defense against infection by RNA viruses
RNA interference
RNA interference is a cellular mechanism to regulate eukaryotic gene expression in a sequence-specific fashion by either inducing degradation of a ______ or inhibiting its translation
messenger RNA
Sn-RNA are short sequences that process initial m-RNA products, and also regulate the production of ______, maintain telomeres, and regulate the action of transcription factors
ribosomal RNA
Small nucleolar RNAs are small RNAs of 60–300 nucleotides in length and are predominantly found in the nucleolus. Most snoRNAs function in posttranscriptional modification of ______, which is important for the production of efficient RNAs
ribosomal RNAs
Sn-RNA (small nuclear RNA) are short sequences that process initial m-RNA products, and also regulate the production of r-RNA, maintain telomeres, and regulate the action of ______ factors
transcription
RNA interference plays an important role not only in regulating genes but also in mediating cellular defense against infection by RNA viruses, including influenza viruses and rhabdoviruses, a group that contains the causative agent of rabies. sn-RNA (small nuclear RNA) are short sequences that process initial m-RNA products, and also regulate the production of r-RNA, maintain telomeres, and regulate the action of ______ factors
transcription
Learn about different types of RNA molecules such as m-RNA, r-RNA, and t-RNA, and their roles in protein synthesis. Understand how the sequences of nitrogenous bases in m-RNA are read by ribosomes to determine protein structure.
