Rosalind Franklin used x-ray diffraction to get a picture of a DNA … Copying information in DNA is efficient because although the information must be copied individually, every single DNA strand still carries the necessary information that can be used in order to copy over during the replication phase. would anyone be able to help me with this question? How did scientists determine that DNA is responsible for storing, copying, and transmitting genetic information. The copying of the information in DNA is straightforward because. Polymerase chain reaction (PCR) is a method widely used to rapidly make millions to billions of copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail. The principle of the method is summarised in Fig. The DNA molecule forms the basis of all known life because its structure enables it to be easily copied within living cells, allowing them to reproduce. Uploaded By imoehlk. DNA replication is an essential part of cell division and the growth of organisms. As the double-helix DNA unwinds into two strands, one strand, called the leading strand, is copied and formed into a new double helix almost as soon as it’s unzipped.

Indeed, the copying of the 5′-AGAG 3′-NP-DNA template was significantly faster and more efficient (about 90% +4 product after 10 min) using 5.0 mM 3′-NH 2-2-MeImpddC and 5.0 mM of the 2-thio monomer 3′-NH 2-2-MeImpddsT when compared to the normal T monomer (Fig. What is the range of function m? However, enzymes can change the shape and supercoiling of the chromosome. B. polyploidy Unrepaired lesions stall the replication machinery, because the highly selective active sites of replicative DNA polymerases cannot accept abnormally shaped nucleotides [1, 2].The bypass of replication impediments is facilitated by specialized translesion synthesis … August 1978; Nucleic Acids Research 5(7):2679-93; DOI: 10.1093/nar/5.7.2679.

Join Yahoo Answers and get 100 points today. RNA "transcripts" are actually made based on the sequence of nucleotides on a strand of DNA — DNA tends to be more robust than RNA because many RNA strands must be made from a single sequence of DNA. Solved: The process of copying a section of DNA into RNA occurs where in the cell? Although single-stranded parental DNA is now available for copying, DNA polymerases cannot begin synthesis of a complementary strand de novo.
