Double stranded DNA consists of two long strands. An adenine on one strand is always paired to a thymine on the opposite strand and a guanine on one strand is always paired to a cytosine on the opposite strand. If a purified DNA has 36% thymine, what arc the percentages of the other bases? A solution has 10 mu g/L of enzyme X, how much enzyme X is in each of the following amounts of solution. 100 mL 50 mL...

Draw a figure of one double stranded DNA molecule that has initiated replication and produced two okazaki fragment in each lagging strand. The figure must include both template strands, all newly synthesized DNA molecules on both leading and lagging strands, all RNA primers, direction of chain growth for each fragment/strand indicated with arrowheads, direction of replication forks. Each molecule must be labeled with the origin of replication on both strands, leading and lagging strands labeled, template or newly synthesized, DNA...

The partial sequence of one strand of a double stranded DNA molecule is: 5’ ---GACGAAGTGCTGCAGAAAGTCCGCGTTATAGGCATGAATTCCTGAGG--- 3’ Write the sequence of both strands of the DNA fragment when this DNA is cleaved with both EcoRI and PstI. The top of your duplex DNA fragment should be derived from the standard sequence given above.

“Unlike what happens in DNA replication, where both strands are copied, only one of the two strands is transcribed into mRNA. The DNA strand that contains the gene is sometimes called the sense strand, or coding strand, and the DNA strand that gets transcribed to give RNA is called the antisense strand, or noncoding strand. Because the sense strand and the antisense strand are complementary, and because the DNA antisense strand and the newly formed RNA strand are also complementary,...

Regarding the four bases in DNA, the double-stranded DNA molecule is held together by complementary bases. In the DNA molecule, guanine binds with ____________ and adenine binds with ____________ in DNA; in RNA, adenine binds with _____________ instead. Therefore, if the codon on the DNA strand is CAG, then the mRNA codon that will bind to it will be _______________.
