NUR4160 Genetics for Nursing Practice FINAL Questions with complete solutions

What is DNA? Correct Answer-A linear, double-stranded structure composed of multiple units of four different nitrogenous bases, each attached to a sugar molecule Bases are nucleoprotiens created from proteins we eat. They can be single ring structures (pyrimidines) or double-ring structures (purines). What are the pyrimidines and what are purines? Correct Answer-Adenine and Guanine are purines. Thymine and cytosine are pyrimidines What is the purpose of a gene? Correct Answer-To code for the synthesis of a specific protein used by a cell, tissue or organ What is transcription? Correct Answer-The process of making RNA that is complementary to the DNA sequence that contains the gene for the protein needed. It processes what RNA does Diff b/w sense and antisense strands Correct Answer-The sense strand of DNA contains the necessary genes and the antisense strand is the template strand. Only the sense DNA strand contains the gene sequence. Antisense strand is the mirror image of the sense strand What is RNA? Correct Answer-Ribonucleic acid; A single stranded copy of DNA that has a ribose sugar (DNA uses deoxyribose) and nitrogen containing bases
