Which statement correctly describes the transcription of DNA? It produces amino acids It produces messenger RNA It results in increased DNA synthesis It is a semi-conservative process It occurs at the surface of the ribosome

How can small interfering RNAS (SİRNAS) and micro RNAS (miRNAs) regulate gene expression? Prevent transcription by binding to DNA and inhibiting transcription factors. Prevent transcription by inducing methylation. Prevent translation by binding to mRNA and degrading the MRNA strand. Prevent translation by binding to MRNA and blocking the ribosome.

Which proteins are required for RNA synthesis? Helicase Primase Sigma factor Ligase RNA polymerase  3 and 5 only 4 and 5 only 1, 2 and 4 only 2, 4 and 5 only 1, 2, 3, 4 and 5
