Question 1 1 pts Why is it important for DNA to have complementary base pairing? O...
Art-Labeling Activity: Structure of the nucleic acids DNA and RNA Reset Double-helical DNA Sugar-phosphate backbone (RNA) Hydrogen bonds Complementary base pairing Phosphate group Deoxyribose Single-stranded RNA Sugar-phosphate backbone (DNA) Base uracil in place of thymine OR AO
QUESTION 10 If an enzyme degraded linker DNA, what would be an immediate consequence? O A. DNA helix would be unable to form O B. nucleosomes would be unable to form a chromatin fiber OC. chromatin fibers would not condense O D.nucleosomes would be unable to form QUESTION 11 This characteristic of DNA allows the molecule to be a template which specifies the sequence of nucleotides in the opposite strand O A. The backbone is phosphate and sugars O B....
1. Very simple toy model for base-pairing of double stranded DNA. (This problem is originally due to Kittel.) DNA is an important biological heteropolymer. A single DNA molecule base-pairs with a complementary DNA molecule to form a duplex double stranded structure. Consider two strands of complementary DNA. Each strand has N monomers. Each monomer is cross- linked by base-pairing to the corresponding monomer on the complementary DNA molecule. Suppose that the energy for breaking a cross link is є and...
Question 7 What is the structure of DNA at the level above the nucleotide? Ladder-like double helix with sugar phosphate backbone forming the rungs of the “ladder” Single-stranded helical structure with sugar phosphate backbone connecting individual nucleotides Single-stranded helical structure with complementary base pairs connecting individual nucleotides Ladder-like double helix with complementary base pairs forming the rungs of the “ladder”
pleasevanswer asap Complementary base-pairing is important in processes involving DNA and RNA, including gene expression. Describe the steps during prokaryotic translation where complementary base-pairing of RNA to RNA is essential to translation. Be sure to include what molecules are complementary, and how this base-pairing contributes to translation. T T T Arial 3 (12pt) T.E.E. 3. 25
Each of the following statements about the structure of DNA may be either true or false. Choose the appropriate answer for each of these statements. Bonding between adenine and thymine on opposite strands involves two hydrogen bonds. Nitrogenous bases are located on the outside of the double helix: phosphates are located towards the middle of the double helix. Bonding between guanine and cytosine on opposite strands involves three hydrogen bonds. DNA and RNA are structurally different due to the difference...
Question 3 (1 point) Match these terms relating to base pairing 1. hydrogen bonds link A-T and G-C. These make "rungs" of DNA ladder shape of RNA 2. number of bonds between Adenine & thymine, or between adenine and uracil complementary base pairing > phosphodiester linkage 3. weak, yet many hold DNA strands together, or RNA that folds back on itself < 2 4. shape of DNA Double helix 5. Single strand, but can fold back on itself to give...
multiple answers are possible! Which of the following statement about DNA is FALSE? When bacteriophage DNA was shown to be the agent necessary for production of new phages, this was the early experiment demonstrating that DNA is the hereditary material. During DNA replication, two replication forks are formed to complete the synthesis of the entire chromosome in eukaryotes. During bacterial DNA replication process, replication forks move in opposite directions away from the origin of replication The molecular structure of DNA...
1) Using the word bank - Conservative, anti-parallel, complementary, parallel, semi-conservative, please answer the questions. A) One stand of DNA runs in the 3' to 5' direction. Its matching strand runs in the opposite direction, 5' to 3'. This is because 2 strands of DNA in a double-helix are: B) According to Chargaff's rule, A always bonds to T and C always bonds to G. The bonding of base pairs is: C) When DNA is replicated, the two original strands...
