Question

Unwinds DNA strand to make replication fork. Adds free nucleotides to the growing daughter DNA strands Adds short pieces of RNA to help DNA polymerase start Removes RNA and replaces with DNA Fuses or "glues" fragments of DNA together Proofreads or edits the DNA, checking for mistakes Given the following, DNA Sequence, what is the new daughter strand? (Did you label the 5' and 3' ends?) What is the name of the "fragments" of DNA on the lagging strand after RNA primers are removed? Number of hydrogen bonds between guanine & cytosine? adenine & thymine? What is the sugar used in backbone of DNA? Challenge question: Do the bases (G, C, A, T) attach to the phosphate or the sugar of a nucleotide? Enzyme that "reads" DNA and makes mRNA Process that converts DNA code to mRNA. The type of RNA that leaves the nucleus to the ribosome. Name of the group of three bases that code for amino acid. RNA that binds amino acids and transfers them to ribosomes. The RNA that makes peptide bonds between amino acids. Process that converts mRNA code into amino acids.

Answer 1

9. three

10. two

11. The backbone of DNA is based on a repeated pattern of a sugar group and a phosphate group. The full name of DNA, deoxyribonucleic acid, gives you the name of the sugar present - deoxyribose. Deoxyribose is a modified form of another sugar called ribose.

13. Transcription begins when an enzyme called RNA polymerase attaches to the DNA template strand and begins assembling a new chain ofnucleotides to produce a complementary RNA strand.

14. Transcription

15. Messenger RNA (mRNA)

16. Three nucleotides encode an amino acid.

17. Transfer RNA (tRNA)

18. tRNA

19. translation
