BIO 105 FINAL EXAM QUESTIONS AND ANSWERS ALREADY PASSED where in the cell cycle is DNA transcription and RNA translation occurring? interphase only Where in the cell cycle is DNA replication occurring? S-phase genes are carried on ___ chromosomes key concept of base pairing hydrogen bond each A with a T hydrogen bond each C with a G about DNA... -the two strands are anti-parallel (opposite polarity) -hydrophobic bases stack in center (hydrophobic effect maximized) -2 strands of DNA are complementary -double helix -deoxyribose -thymine What is DNA polymerase? -creates DNA molecules by assembling nucleotides -is needed to replicate DNA -adds new nucleotides to the 3' end new nucleotides are always added to the ____ end of the polymer 3' end what is semi-conservative replication? newly replicated DNA has one old strand and one newly synthesized strand nucleotides condense to form a ___ single biopolymer RNA is like DNA except it has ___ instead of a -H group and is _____ instead of deoxyribose -OH, ribose DNA polymerase makes the _____ leading strand DNA primase makes ____ another RNA primer for the lagging strand DNA is kept in the ____ of eukaryotic cells nucleus Proteins are made outside the _____ in the cytosol nucleus DNA information is ____ into a message that is ___ from the nucleus transcribed, exported promoter region -has binding sites for transcription factors (recruit RNA polymerase onto the DNA) -has binding sites for other factors that can un-pack or un-wind the chromatin to allow transcription -specifies where the RNA polymerase should start transcription transcribed region -template strand of DNA- serves as a template to make an RNA copy of the non-template strand of DNA -the RNA copy specifies where translation should start and end & the amino acid sequence of the encoded protein terminator region -has binding
