Chromosome. Polymeric Structure. Polymer ideal for informational molecule. Ribose and deoxyribose. Nucleic Acids. What do we know already?. i. . The nucleic acids DNA and RNA are polymers of nucleotides. Nucleotides consist of 3 parts. A 5-carbon sugar – ribose or deoxyribose. A phosphate group (acidic & negatively-charged). 2.6 Structure of DNA & RNA. Understandings:. The nucleic acids DNA & RNA are polymers of nucleotides.. DNA differs from RNA in the # of strands normally present, the base composition & type of pentose.. Sash Chain. Sash Chain is sold by the foot. Used to hang light fixtures, etc. . Twist Link Chain. Used where the chain must travel easily over something (links don’t get caught).. Double Loop Chain. BMI/CS 776 . www.biostat.wisc.edu/bmi776/. Spring . 2018. Anthony Gitter. gitter@biostat.wisc.edu.

The genes in DNA code for instructions that control the production of proteins within the cells. The first step in decoding these genetic messages is to copy DNA into . RNA (transcription). These RNA molecules contain coded information for making proteins. . RNA is made of a long chain of nucleotides.. Differences between DNA and RNA:. 1 – the sugar on RNA is ribose instead of deoxyribose. 2 – RNA is generally single-stranded. 3 – RNA contains uracil in place of thymine. Proteins are biopolymers, made of the 20 L- . α. -amino acids linked by peptide bonds.. Polypeptide backbone is a repeating sequence of. . N-C-C-N-C-C…. The side chain or R group is not a part of the backbone or the peptide bond.. .. The length of the transcription bubble is about 12 to 14 . bp. , but the length of the RNA–DNA hybrid within the bubble is only 8 to 9 . bp. .
