polymeraseDuring transcription, the enzyme RNA _____ catalyzes the copying of base codes in a gene from DNA to a complementary strand of mRNA. Where does this strand go?10true
NucleotidesQuestion: What are nucleic acid monomers called?21false
HelicaseQuestion: What molecule begins DNA replication?41false
True.Question: True or False: One sugar-phosphate chain runs in the 5' to 3' direction and the other runs in the 3' to 5' direction.61false
determinesTrue or False: The order of amino acids in a protein _____ the protein’s structure and function. To make a protein the gene containing the DNA, coding for that protein must first be converted into an RNA molecule.80true
False.Question: True or False: DNA is not a polar molecule, so it cannot be easily dissolved in water, but dissolves in non-polar solvents such as alcohol.111false
anotherSuppose a scientist extracts DNA from one cell and inserts it into _____ cell. What is the scientist most likely trying to accomplish?120true
translationalWhich of the following is NOT a type of RNA? Ribosomal, messenger, _____, transfer130true
A, T, C, GQuestion: How are the four DNA bases typically abbreviated?141false
calledThe DNA of prokaryotes is usually arranged in a single circular chromosome that is located in an area _____ the nucleoid and may be loosely tethered to the cell membrane.151true
MessengerThe process of building a protein based on a RNA template. _____ RNA (mRNA) strands are used as the code to assemble amino acids in the correct order to form a protein.161true
backboneWhat charge is the DNA phosphate in the _____?170true
DNA; ribosomal RNAQuestion: Messenger RNA delivers a "message" from ________ to ________.181false
nucleotidesTrue or False: DNA polymerase can add _____ only to a free 3' end of a growing segment, never to a 5' end, so DNA synthesis can occur in the 5' to 3' direction only.190true
repeatingNucleic acids are large polymers made up of smaller _____ units, or monomers.201true
moleculeWhich of the following best describes the structure of a typical _____ of DNA?210true
codonsTrue or False: Different _____ code for unique amino acids. Some amino acids may not be coded for by more than one codon.230true
Protein synthesis.Question: Ribosomes are made of another kind of RNA called ribosomal RNA (rRNA). What occurs here?251false
proteinsRNA is single stranded, some RNA molecules form folded structures, and, like _____, these folded RNA molecules perform various functions like catalyzing reactions and transporting molecules.261true
ProteinQuestion: Many amino acids come together to form a ________.281false
