Answer:
B). A/T base pairs
Explanation:
Guanine pairs with Cytosine with three hydrogen bonds whereas adenine pairs with thymine with two hydrogen bonds. To break two hydrogen bonds is easy to unwind DNA. So it is easiest to unwind DNA at regions that contain a log A/T base pairs.
It is easiest to unwind DNA at regions that contain a lot of A. G/C base...
________ found in the -10 sequence makes it easier for the DNA to separate. A. G-C base pairs B. Template strands C. Non-template strands D. A-T base pairs E. Start codons 9.)Your labmate’s ligation reaction didn’t work. The regular ATP had run out, so he fueled the reaction with dATP from the PCR kit. What advice can you give him? A. Suggest trying one of the other nucleotides from the PCR kit to drive the ligation reaction. B. Suggest adding...
Biochemistry homework 4. Explain why A-T and G-C are the only base pairs possible in normal double stranded DNA? 5. Match the appropriate characteristics in the right column with the structures of double strand or single strand DNA. (A) double-strand DNA: (B) single-strand DNA: (i) is a rigid rod (ii) shows a greater hyperchromic effect. (iii) contains equal amount of A and T bases. (iv) may contain different amounts of C and G bases. (v) contains U rather than T...
DNA fingerprinting is based on regions of DNA that are variable between individuals. Many of these differences between individuals produce no change in phenotype. This type of mutation is a(n) O a) deletion Ob) insertion Oc) silent mutation. d) substitution mutation. Question 8 (2 points) The order of the base pairs in a DNA molecule a) differs from species to species. b) is identical in all organisms.
A double-stranded DNA molecule of 175 base pairs long had (A+T/(G+C) = 0.75. How many adenine nucleotides are there in this DNA? 75 37.5 150
1. Answer the following questions concerning a section of double-stranded DNA containing 1000 base pairs. a. If the DNA contains 28% adenosine residues, how many guanosine residues are in the DNA? b. Are the nucleotide compositions of each of the two individual strands of DNA identical? Explain. c. If the DNA is entirely in the B-DNA conformation: i. How many helical turns does the DNA contain? ii. What is the length of the DNA? 2. Write the sequence of a...
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...
1. A DNA base pair is _____ forming_____ hydrogen bonds a. C with T : two b. G with T : three c. A with C : three d. G with C : two e. A with T : two 2. the correct order of action of these enzymes in DNA replication is a. Helicase, primase, DNA polymerase, Ligase. b. transferase, primase, DNA polymerase , helicase c. DNA polymerase , ligase , helicase, primase d. ligase, primase , helicase ,...
DNA sequences are made up of 4 bases: A (adenine), C (cytosine), G (guanine), or T (thymine). How many 8-element DNA sequences a) Do not end with C or T? b) Start with A and ends with T? c) Start with G? d) Contain only G or C?
The average molecular weight of a nucleotide (base + deoxyribose + 1 phosphate group) in DNA is 308g/mol of 308 Daltons (Da). This number is the average molecular weight of A = 312.2 g/mol G = 328.2 g/mol C = 288.2 g/mol T = 303.2 g/mol 55 R-plasmid was used for the transformation experiment a.What is the size of this plasmid (in kilo base pairs; kbp)? How many bases is this? b. What is the molecular weight of one plasmid...
