WebThis type of RNA is called a messenger RNA ( mRNA ), as it serves as a messenger between DNA and the ribosomes, molecular machines that read mRNA sequences and use them to build proteins. This progression from DNA to RNA to protein is called the “ central dogma ” of molecular biology. Importantly, not all genes encode protein products. WebStage two. DNA polymerase will add the free DNA nucleotides using complementary base pairing (A-T and C-G) to the 3’ end of the primer this will allow the new DNA strand to …

RNA’s larger helical grooves mean it is more easily subject to attack by enzymes. Ultraviolet (UV) Sensitivity. DNA is vulnerable to damage by ultraviolet light. RNA is more resistant to damage from UV light than DNA.

WebThe DNA double helix is rewound by RNA polymerase at the rear of the transcription bubble. Like how two adjacent zippers work, when pulled together, they unzip and rezip as they proceed in a particular direction. Various factors can cause double-stranded DNA to break; thus, reorder genes or cause cell death. RNA-DNA hybrid
