Question

t sequence of enzymes necessary for DNA replication are he Meli Primase, Topoisomerase. b) Helicase To c) Helicase, Ton merase, Primase, DNA D merase II, and DNA Ligase erase, DNA Polymerasei t , and DNA Ligase d) Helicase, Topoisomerase, Primase, DNA Polymerase I, and DNA Ligase dDNA Ligase 58. DNA tesized in the 31 5' direction b) False 59. Eukaryotes have a single origin or replication a) True b) False Okaz 6U- KI Fragments are synthesized in the 3'-5' direction b) False 61. The central dogma of molecular biology states that DNA RNA Protein. This is only untrue for retroviruses a) True b) False 62. The TATA box is a promoter sequence that is common in prokaryotes and eukaryotes a) True b) False 63. RNA polymerase unwinds DNA and synthesizes a mRNA transcript a True b) False 64. The stages of transcription include initiation, elongation and termination. Inititation is contingent upon RNA polymerase and transcription factor binding to a promotor sequence, elongation occurs in the 3'-5" Direction, and sthe polymerase disassociates because of a termination sequence termination occurs a) True b) False 65. In eukaryotes, related genes are located in a sequence together and regulated by the same promotor site. These are called exons a) True b) False 66. Exons are ligated together by the action of the spliceosome while introns are cut. Together, this leads to the production of a matured MRNA transcript if the 5' cap and Poly A tail are present. a) True b) False 67. The TRNA contains the codon which reads the MRNA a) True b) False
