WebApr 11, 2024 · Introduction. RAS genes are among the most mutated proto-oncogenes in human cancers, with around 20% of all malignancies estimated to harbor oncogenic mutations in one of the three highly homologous KRAS, NRAS, or HRAS genes (Prior et al, 2024).The encoded RAS proteins are small GTPases which function as molecular … WebMicroRNAs (miRNAs) are a class of small, endogenous RNAs of 21-25 nucleotides (nts) in length. They play an important regulatory role in animals and plants by targeting specific mRNAs for degradation or translation repression. Recent scientific advances have revealed the synthesis pathways and the regulatory mechanisms of miRNAs in animals and ...

WebSynthesis of RNA is usually catalyzed by an enzyme— RNA polymerase —using DNA as a template, a process known as transcription. Initiation of transcription begins with the binding of the enzyme to a promoter sequence in the DNA (usually found "upstream" of a gene). The DNA double helix is unwound by the helicase activity of the enzyme. WebFunction and synthesis of small nucleolar RNAs.
