I having a hard time understanding this since the both template strand in the end is the same the G in 5' -3' and G 3'-5' is it possible to replicate it? Can you explain it? Thank you so much.
DNA STRAND IS 3’ TAC-AGC-ACT-CAG-TCA 5’, whats the non-template/sense/coding strand from the STARND DNA? also what's the arrangement of m-RNA and the chain arrangement of the amino acids that will be made according to the order of the RNA?PLS DONT ANSWER THE DEFINITION ONLY, READ THE QUESTION CAREFULLY
The two strands for the helix-shaped DNA molecule are heldtogether by electrostatic forces as shown in class. Due to electron sharing, themagnitude of the net average charge on the H and N atoms, each, is 0.2e. Thenet average charge on the C and O atoms, each, is 0.4e. The distance betweenany two adjacent atoms on the same molecule is 0.1nm. Since electric fieldsdecrease as an inverse square law, they die off quickly with distance. So, theonly fields that really contribute to any given bond are due to the 3 atomsalong the red dotted line in the class diagram (two atoms on one'molecule andone atom on the other molecule).Calculate the electric fields and net force between a thymineand an adenine pair.=Calculate the electric fields and net force between a cytosineand a guanine pair.nConsider the OHN bond in the AT nucleotide. Can theelectric field be zero anywhere along the axis of this bond? If not,explain why not. If so, find where the electric field is zero.
Microbiology q you introduced mutations into bacteria. However, the bacteria have the same characteristics as before. What kind of mutations do the bacteria have? O base deletion Oframeshift O missense O silent O nonsense
Part 4. Putting It Together 1) Consider the diagram below as well as the given information. This diagram represents a piece of circular DNA which was cut in 4 separate reactions (4 different test tubes, each with some of this DNA in it). One digest was done with AvaI, another with ClaI, a third with EcoRV, and a fourth with ScaI. The locations of the recognition sequences for each restriction enzyme are shown along with the location of that site in bp along the circle (it goes clockwise from position 1). You run an agarose gel with a molecular weight marker in the first lane, the AvaI digest in lane 2, the ClaI digest in lane 3, the EcoRV digest in lane 4, and the ScaI digest in lane 5. a) Use the space below and draw out the agarose gel described above. Use your drawing to answer the next questions. b) How many bands of DNA are there in lane 3? c) How many bands of DNA are there in lane 5? d) There would be 2 bands of DNA in lane 4. How big are they? e) Which lane…

HersheyChase Experiments The graph shown in FIGURE 8.5 is reproduced from an original 1952 publication by Hershey and Chase. Bacteriophage were labeled with radioactive tracers and allowed 10 infect bacteria. The virusbacteria mixtures were then whirled in a blender to dislodge any viral components attached to the exterior of the bacteria. Afterward, radioactivity from the tracers was measured. FIGURE 8.5 Detail of Alfred Hershey and Martha Chases 1952 publication describing their experiments with bacteriophage. Infected bacteria refers to the percentage of bacteria that survived the blender. The extracellular concentration of which isotope increased the most with blending?
