Describe how the biochemistry of DNA can explain the DNA double helix structure.
Describe how the biochemistry of DNA can explain the DNA double helix structure.
1. Describe how the structure of DNA (double helix and base pair rule) is correlated with its role as the molecular basis of inheritance and uniqueness. 2. Discuss how this correlation (above) allows scientists to use DNA for the following area: You will describe DNA technology in the "medical field".
1. Describe the structure of the DNA molecule and how this structure allows for the storage of information, the replication of DNA, and protein synthesis. • What is the double helix? What are nucleotides, polynucleotide and base pairs? Use these terms to explain the structure of DNA. 2. List the similarities and differences between the various nucleic acid molecules. • What is semi-conservative replication of DNA? How does DNA get replicated?
During both DNA replication and PCR the DNA double helix must be unwound. Explain how this is achieved during each process.
1. During both DNA replication and PCR the DNA double helix must be unwound. Explain how this is achieved during each process. 2. A methylguanosine cap and poly A tail are added to what molecule? Why are these processing steps important for the cell?
BIOCHEMISTRY 2points each 1. Describe the DNA helix proposed by Watson and Crisk A) The Watson and Crick DNA model contains two DNA polymer strands coiled around a B) The strands are oriented in opposite directions, from S to 3 (antiparallel), and the two C) The sugar-phosphate backbone is located on the outside. The base pairs are stacked in the common axis. strands are twisted in a right-handed coil. center of the helix and are stabilized by specific hydrogen bonds...
Biochemistry Lecture 6-Nucleic Acid Structure Question: Define the terms "major groove" and "minor groove" with respect to the DNA double helix, and explain why the molecule has these characteristics. (Typed or neat handwriting pleasant thank you!)
Describe hydrogen bonding in the α-helix of proteins and hydrogen bonding on the double helix of DNA, be sure to highlight the similarities and differences. Include in the answer the role of hydrogen bonding in these two structures.
Select the phrases that accurately describe properties of the most common form of the DNA double helix. There is more than one correct answer. Select all that apply. DNA contains equal amounts of adenine and thymine, and equal amounts of cytosine and guanine. A helical turn consists of about 10 nucleotides. Base pairs have a spacing of 20 A. The phosphodiester bonds between nucleotide residues run in opposite directions in the two strands. The nitrogenous bases are exposed to the solvent, whereas the sugar-phosphate backbone of...
Compare A-DNA, B-DNA, and Z-DNA double helix conformations.
why can you not see the double helix when observing the DNA under a microscope?
