1)Chargaff's rules state that DNA from any cell of any organisms should have a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.
2)DNA structure
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
3)A nucleotide consists of three things: A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine (in the case of RNA, thymine is replaced by uracil). A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons. One or more phosphate groups.
4)DNA replication is said to be semi-conservative because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand. ... Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.
5)The diagram has show in above.
6)complementary base pairing is necessary because the double helix shape would not be the same if not. Doubles would only pair with doubles and the singles to singles.

in theory yes but at the same time you would have to reverse enginere it and have it reject the fruit flys dna strands

Answer: The correct answer is D) The number of chromosomes remains the same in mitosis and is reduced by half in meiosis.
Explanation-
Mitosis and meiosis are the two forms of cell division. Mitosis occurs in all the living organisms. In mitosis, cell divides into two daughter, each having equal number of chromosomes with that of the parental cell. It is also a process of asexual reproduction.
Whereas, meiosis typically occurs in sexually reproducing organisms during gamete formation. In this process, the number of chromosomes are reduced to half as the homologous chromosomes are separated.
Thus, the number of chromosomes remains the same in mitosis and it is reduced by half in meiosis.
