the assembly of new nucleotides directed by the enzyme _?_ _?_.130 &Fig8.10Semiconservative” means that after replication one strand is “_?_” and one stand is “_?_”.131How does the cell check for errors in DNA replication?Chapter 9: From DNA to Protein138The information in DNA is specifically stored in the linear _?_ of its bases.138A subset of the DNA sequence that specifies a protein is known as a _?_.Fig9.12Where in the cell does transcription takeplace?138In the transcription process, the information in DNA is transferred to what similar molecule?138RNA and DNA differences:DNA is double-stranded; RNA is _?_-stranded;The sugar in DNA is deoxyribose; the sugar in RNA is _?_;DNA has A, G, C, and T; RNA has A, G, C, and _?_;DNA is basically of one kind; RNA comes in _?_ (#) main varieties.138Name and describe the role of each of the THREE kinds of RNA.

Fig9.12Where in the cell does translation take place?139In translation the message from mRNA gets decoded to assemble a _?_ molecule.139The result of transcription, followed by translation, is called gene _?_.140What enzyme is used in transcription?140T or F: In transcription both strands of DNA are copied into mRNA.140T or F: In transcription only a portionof the DNA template strand unwinds at a given time.141At the conclusion of transcription, a single-stranded mRNA with a base sequence that is _?_ to that of the DNA template is formed.In post-transcription “editing,” the _?_ sequences are removed leaving a mature transcript of _?_.Even though mRNA is a linear sequence of many bases, the transcript is “read” only_?_ (#) bases at a time?Each triplet of 3 “words” is called a _?_.142and Fig9.7The collection of 64 codons is called the_?_ _?_.Fig 9.7There is at least ONE (some more) codon for each of the _?_ _?_ that will be assembled into a finished protein.142The first codon in all transcripts is _?_ which codes for the amino acid methonine.Fig 9.7Three of the codons do NOT code for any amino acid; these are called _?_ codons.143What type of RNA comprises the ribosome?What type of RNA carries the amino

acids to the ribosomes for protein assembly?Fig9.10On one end of the tRNA molecule there is a triplet of bases that will be complementary to the codon of mRNA; this is called the _?_.Fig9.10At the other end of the tRNA is an attachment site for an _?_ _?_ that is specific to thatRNA.144_?_ is the process that converts the information carried in mRNA into a polypeptide.Fig 9.11To begin synthesis of a polypeptide, the first mRNA codon is _?_, which in turn pairs with a tRNA bearing an anticodon of _?_, itself carrying the amino acid called _?_.Fig 9.11To elongate the polypeptide chain, a second amino acid is brought along sidethe first and a _?_ bond joins the two amino acids.Fig 9.11This process will repeated until a _?_ codon is reached causing termination ofthe assembly.146A permanent change in the sequence ofDNA is called a _?_.146-147Mutations can occur when:a base is removed, called a _?_;extra bases are added called an _?_;a _?_-pair substitution occurs.147What is the genetic cause of sickle-cell anemia?147
