A. In the product, the underlined regions are called what? B. What functional groups are present in the highlighted 5' and 3' ends of the DNA products?

The A and G compositions (mole percent) of one of the strands of a duplex DNA is A = 27 and G = 30. (a) What would be the T and C compositions of the complementary strand? (b) What can be said about the A and G compositions of its complementary strand?

Assume that the molar percentage of thymine in a double stranded DNA is 20. What are the percentages of the four bases (G, C, T, A)? b. The base content of a sample of DNA is as follows: A=31% G=31% T=19% C=19%. What conclusion can be drawn from this information?

It is known    that    double    stranded    DNA    is    denatured    at    low    pH.     pKa values    should    allow    the    determination    of    whether    this    is    due    to    perturbation    of    the    hydrogen    bonding    in    A-T    and/or    G-C    base    pairs.    The    table    gives    values    for    the    pKas    of different    protonated    groups    in    the    nucleobases.Nucleobase Position    &    pKa                    A             N1,            3.5                    G             N7,            1.6;                N1,    9.2                    C             N3,        4.2                    T             N3,        9.7a)   Draw    the    A-T    and    G-C    base    pairs.                - Label    the    bases    with    the    one-letter    code.    –        - Number    the    atoms    in    the    rings and    label    the    atom    that    attaches    to    the    sugar.                - Mark the groups that interact in normal…

5- ddNTP differs from dNTP in..... and N is representing.. a) The first has no OH in both C 1,2, but dNTP has OH in C3 of the sugar/A, G.T.C. b) The first has no OH in both C 2 & 3, but dNTP has OH in C3 of the sugar/the bases. c) ddNTP is used to stop DNA elongation / nitrogen d) ddNTP has only one OH in C3/A,G,T.,C

Pls help

13. please answer, i'll give thumbs up

You add 1 ul of EcoRI into 50 ul of your reaction of which contains 10 ug of DNA. How long would it take to completely digest the DNA?

5'-GCGGTACGTTACGGCTTTACTGACCTGCAGGC-3' A. Convert this to a double strand DNA molecule by writing the complementary sequence. Be sure to correctly label the ends of the double stranded molecule B. Pick one of the two strands and write the sequence of an RNA molecule that could be transcribed from it. Again, you must correctly label the ends of the molecule.
