(a) The diagram below shows a section of a messenger RNA (mRNA) molecule.<\/p>\n (i) Name the sugar that is present in mRNA. (b) DNA templates are used to produce mRNA molecules. (ii)Apart from free RNA nucleotides and a DNA template, name one other molecule that is essential for mRNA synthesis. c) The table below gives some information about proteins. In your jotter, provide the missing information to correctly complete the table.<\/p>\n (a) Two types of RNA are visible on the diagram. Name the third type of RNA, not visible on the diagram, and state its role in the cell. Use information from the table to identify amino acids 1 and 4.<\/p>\n 3.<\/p>\n (a) The diagram below illustrates the two main stages of protein synthesis.<\/p>\n Describe three differences between DNA and mRNA.<\/p>\n (b) Name bases 3, 8 and 11. 4.
