Question
The information encoded by the DNA is specified by the: sugar-phosphate backbone of the DNA molecule number of separate DNA strands size of a particular chromosome nucleotide sequence of the DNA molecule number of bases in a DNA molecule Errors in DNA replication can come from: DNA polymerase DNA ligase complementary base pairing sun's UV radiation Okazaki fragments The ends of eukaryotic chromosomes called ______, shorten with every cell division Centromeres Telomeres Kinetochores Primosomes Nucleosomes The ends of eukaryotic chromosomes can be lengthened by the enzyme called: apoptosis mismatch repair enzymes primase telomerase DNA polymerase Because a newly synthesined DNA molecule contains _____, the replication process is said to be semicemersvative two new strands one parental strand and one new strand two parental strands half purines and half pyimidines Who first confirmed that the replication of DNA was semiconservative Chargaff and Hershey Watson and Crick Avery and Griffith Meselson and Stahl Watson, Crik and Wilkins If DNA replication rejeined the two parental strands it would be termed: disgentive gradient semicenservative parental conservative Which the following causes the unwinding of the DNA double helix? DNA polymerase DNA helicase RNA primer primavome RNA polymerase In replication, once the DNA strands have been separated reformation of the double helix is prevented by: DNA helicase enryme single-strand binding proteins DNA polymerases ATP DNA Primase Enzymes called _______ feor breaks in the DNA molecules to prevent the formation of knots in the DN helin during replication: topoisomerases. single strand binding proteins DNA polymerases RNA polymerases DNA ligases Which of the following adds. new nucleotides to a growing DNA chain DNA polymerase DNA helicase RNA primer primase RNA polymerase Why does DNA synthesis proceed in a 5' to 3' ?Explanation / Answer
15. From th DNA X-ray crystallography data Franklin and Wilkins inferred that phosphate are stacked liked rungs on a ladder , DNA is helical while Watson and crick determined that DNA is helical the flat nucleotide bases are stacked upon each other.
16. The information encoded by DNA is specified by the neuloctide sequence of dna molecule
17. Errors in DNA replication can come from Dna polymerase
18. The ends of Eukaryotic chromosomes called telomeres, shorten with every cell division.
19. The ends of eukaryotic chromosomes can be lengthened by enzyme called telomerase
