17. Spinocerebellar Ataxia Type 2 is a trinucleotide expansion disorder. Normal individuals have up to 32 trinucleotide repeats, and individuals with 33 or more repeats develop symptoms. You have a pair of 20-nucleotide-long PCR primers for genotyping. The 5' end of each primer begins 25 nucleotides outside of the repeat. How long a PCR fragment would be indicative of the shortest product found in someone likely to develop the disease? a-83 b.99 32 Sheal they 33+-diseased C. 139 d. 149 ts e. 189 33 X 3 X 3 99+50+40 99 1 +
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
