False - Correct answer-T/F Uridine is a nucleotide in DNA. False - Correct answer-T/F RNA is double stranded. Introns - Correct answer-During mRNA maturation what is the name of the part of the mRNA that is removed? Free or Membrane Bound - Correct answer-There are two types of protein synthesis in eukaryotic cells. These two types can be distinguished because the polyribosome is either or . Ribose - Correct answer-Which sugar is present in RNA? Leading strand - Correct answer-Which strand is produced more rapidly? T or thymidine - Correct answer-In DNA, what does the nucleotide labeled as A pair with? Nucleosome - Correct answer-The double helix of DNA is wrapped about 1¾ times around which of these components? RNA splicing - Correct answer-List one type of post-translational modification. Nucleic acid to amino acid - Correct answer-Protein synthesis changes from the language of to the language of . - Correct answer-Draw the sugar in DNA and label the carbons as discussed in the lecture. Then circle the carbon that is different in RNA. Helicase - Correct answer-Which enzyme unwraps the double helix? 12 - Correct answer-Assume that you have a eukaryotic cell with three chromosomes within it. How many 5' ends would there be? Primase - Correct answer-For DNA Polymerase III to work which of these components has to act first? Okazaki fragments - Correct answer-During DNA replication in the lagging strand there is production of this component? True - Correct answer-T/F During DNA replication is greatly reduced by enzymes that proof read the newly replicated DNA. initiation, elongation, termination - Correct answer-RNA synthesis, also called RNA transcription occurs in three phases. List them from beginning to end in order. Primase - Correct answer-Which enzyme is used first to permit DNA polymerase III to begin replicating the 3' strand? True - Correct answer-T/F The genetic code for the conversion of mRNA codons to proteins has redundancy. AUG - Correct answer-In eukaryotic cells the start codon for protein synthesis is . 3 - Correct answer-How many "stop" codons exist? 2 - Correct answer-How many hydrogen bonds are there between an A and its paired nucleotide? False - Correct answer-T/F The DNA polymerase that replicates the parental strand of DNA reads the parental DNA from 5' to 3" and makes a new DNA strand from 3' to 5'. True - Correct answer-T/F Replication of DNA is semi-conservative. False - Correct answer-T/F Strands of the backbone of DNA are parallel? True - Correct answer-T/F In the lagging stand, the DNA is read from the parental DNA's 3' to 5' end. True - Correct answer-T/F DNA replication in eukaryotes is sped up by multiple origins of replication. Rubisco - Correct answer-The most abundant protein in the world is called Thylakoid - Correct answer-The antenna system is in the _____________ membranes. Light, water, CO2 - Correct answer-List three items required for photosynthesis to occur. ATP - Correct answer-Glycolysis requires the investment of two_________ in order to obtain a gross output of four ________ . False - Correct answer-T/F The cell does not need ATP to survive. mitochondrial matrix - Correct answer-Specifically where in a cell does the citric acid/Kreb's cycle occur? Cytoplasm - Correct answer-Specifically in a cell where does Glycolysis occur? True - Correct answer-T/F The citric acid/Kreb's cycle breaks down carbohydrates into CO2. mitochondrial matrix - Correct answer-Where is carbon dioxide produced? True - Correct answer-T/F FADH2 results as one of the products of the citric acid cycle. True - Correct answer-T/F Having a fever of 100 oF can help you fight off infections. False - Correct answer-Natural killer cells are part of the specific immune system. True - Correct answer-T/F A bacterium coated by antibodies is a signal that a macrophage should endocytose (eat) it False - Correct answer-T/F Bone marrow is a site where mature immune cells are found. The leg muscles contracting and moving force the fluid up the leg where it is a one way valve and can not come back down. - Correct answer-How does the lymph fluid return from the legs to the circulatory system? True - Correct answer-T/F There are times when the spleen can be considered to be the primary lymph node. True - Correct answer-T/F Red blood cells originate from the bone marrow. False - Correct answer-T/F You should have your appendix removed whenever possible. True - Correct answer-T/F Memory cells "remember" the antigen and make a faster and greater response the next time the antigen is encountered
