BSC 108 Exam 3 Questions And Answers structure of DNA - ANS composed of nucleotide subunits - has sugar - phosphate backbone (deoxyribose and phosphate) DNA - ANS deoxyribonucleic acid nitrogen - containing bases - ANS adenine, guanine, thymine, cytosine adenine, guanine, thymine, cytosine - ANS held together by hydrogen bonds adenine = thymine guanine = cytosine - ANS always pair together (DNA) DNA replication - ANS - 1 parent has 2 strands of separates...

Describe the process of transcription. What are the starting molecules and the end products? - Transcription is the manufacture of a strand of RNA complementary to a strand of DNA. In initiation, RNA polymerase binds to a promoter region on the DNA strand. RNA synthesis occurs during the elongation phase as RNA nucleotides are added to the growing RNA polynucleotide. When the RNA polymerase reaches the terminator region of the gene, elongation stops and the polymerase and new RNA molecule d...
