What is Chargaff's Rule and how was it important for determining DNA's structure?
Wiki User
∙ 11y ago
Erwin Chargaff discovered the comlimentary base pairing and also the amount of purines is equal to that of pyrimidines. This discovery helped Watson and Crick in proposing the double helical structure of DNA in which the two stands are held together by hydrogen bonding between the nucleotide bases as proposed by Chargaff.

∙ 11y agoIt was a rule created by Erwin Chargaff that stated that the amount of adenine must be equal to the amount of thymine, and furthermore that the amount of guanine is equal to the amount of cytosine in DNA.
When watson and crick where making the model of DNA, and had figured out that it was a double helix
(from basically taking Rosalind Franklin
's work) they were able to use this piece of information and conclude that the two strands of the double helix are held together by the pairing of these base groups. They were able to understand that A and T formed single hydrogen bonds
and G and C formed double hydrogen bonds to hold the helix together.

Who discovered DNAs shape?
Francis Crick Dr. Rosalin Franklin and pro. Maurice Wilklins discovered the shape of DNA.
How many strands of DNA is present in a primary spermatocyte?
There are only two strands within the DNA that is present in a primary spermatocyte. There are many double stranded breakage DNAs withing the spermatocyte.
What is a linker DNA?
Linker DNA links adjacent nucleosome core particles to each other. They then resemble beads on a string. These linker DNAs are readily removed through exonuclease hydrolysis.
What are the different enzymes in the DNA?
Biological catalysis is dominated by enzymes that are made of protein, but several distinct classes of catalytic RNAs are known to promote chemical transformations that are fundamental to cellular metabolism. Is biological catalysis limited only to these two biopolymers, or is DNA also capable of functioning as an enzyme in nature? To date, no DNA enzymes of natural origin have been found. However, an increasing number of catalytic DNAs, with characteristics that are similar to those of ribozymes, are being produced outside the confines of the cell. An assessment of the potential for structure formation by DNA leads to the conclusion that DNA might have considerable latent potential for enzymatic function.
Is DNA important for living beings.Explain with example?
without DNA, we are nothing Yes, because our dnas created everything in us. it is the beginning of life.
Does viruses have dnas?
Some do, some don't

Is it possible to not receive DNA from all great grandparents?
No, it is not possible not to receive DNA from all the great grandparents because our parents have their DNAs.

The four bases in the DNA molecule are the cell's?
I presume this is refereing to the 4 nucleotide bases which make up part of DNAs structure They form pairs and are Adenine, Guanine, Cytosine and Thymine RNA is very similar but has Uracil instead of Thymine Hope that helps get your some nice welsh hand made jewellry for mothersday Diesel Danger Nutkins
Does your body need nitrogen?
yes. nitrogen is a main component in our DNAs and also in other parts of our body. the elements in variable proportion are found in our body parts.
When the cell splits how does the DNA not get damaged?
DNA is part of chromosome, and will not be affected. The cell splits in chromosomes. There may be some DNAs damaged, but this is in very very small numbers.
What is kept in the DNA of the nucleus?
In this nucleus, there exist chromosomes. These chromosomes are made up of double helix structures called DNAs. DNAs contains genes. Genes are what codes for protein synthesis. The genetic information and coding are all kept in the genes. A gene is the basic unit of inheritance. Coding makes replicating efficient. Think of it as a photo-copying machine. All you need to do is to process the same product with the same input code you have.
