- Background: DNA nucleotides (i.e A, T, G, and C) are naturally found in a paired, or bonded, arrangement (i.e. the double helix) within the nucleus of every cell. This structure makes the process of replication that occurs prior to mitosis and meiosis very reliable. The purpose of DNA, though, is not simply to make copies of itself, but to provide a set of instructions for the synthesis or "construction" of biomolecules, such as proteins. Why is transcription (i.e. the formation of an RNA copy of a given gene) a necessary step in the "construction" process highlighted above? What is the cell looking to ultimately do with this RNA information?arrow_forwardLook at the picture carefully below and imagine inside a cell nucleus. a) encircle and name the parts where DNA is most accessible and least accessible b) how nucleosome positioning or spacing can interfere with DNA accessiblityarrow_forwardDescribe the structure of DNA.

Draw arrows connecting the concepts as appropriate, and label the arrows to indicate the relationship between those concepts. Typically, nouns will be the nodes of the map. Verbs and connecting ideas should be written on the connecting arrows. Illustrations of the central phenomena (replication, transcription, translation) are mandatory, and you must develop your own pictures. You can draw them by hand or use a computer illustrating program to draw, but you may not screenshot images from the internet.
