EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know … Chargaff’s rule (the equivalence rule): He found out that in DNA, the concentration of adenine always equalled the concentration of thymine and the concentration of guanine always equalled the concentration of cytosine ie. the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. As for which parent provides which traits, both parents provide 50% of the pup's genetic make-up. Chargaff’s rules are based on complementary base paring between nitrogenous bases of two antiparallel strands of a double stranded DNA molecule and thus are applicable to double stranded DNA only. It was shown that it does not apply to organellar genomes (mitochondria and plastids) smaller than ~20-30 kbp, single stranded DNA (viral) genomes or any type of RNA genome. The Questions and Wiki User Answered 2013-02-14 23:43:26. Research. The rule states that DNA from any cell of all organisms should have a 1:1 ratio (base pair rule) of pyrimidine and purine bases, i.e. Why single stranded RNA does not obey Chargaff's rule?

If you have the first one, T/T, both parents contributes the black allele and the tongue will be black. Therefore Chargaff's rule doesn't work in single stranded DNA. So a base pair is composed of a pyrimidine base and a purine base. How do you think about the answers? >NOPE, Viruses don't have DNA, they have RNA and chargaff's rule is applicable only to DNA. in many viruses in some regions their single stranded DNA become locally double stranded due to internal complementarity.

The second of Chargaff's rules (or "Chargaff's second parity rule") is that the composition of DNA varies from one species to another; in particular in the relative amounts of A, G, T, and C bases. Parity rule 2 says that in single stranded DNA of eucaryotes A approximates T and G approximates C..it is observational of multiple experiments. How long T-cells and thrombocytes survive? The REASON there is the same amount of A as T in DNA is because in a double helix, an A in one strand hydrogen bonds with a T in the other. Multivariate statistical analysis of codon use within genomes with unequal quantities of coding sequences on the two strands has shown that codon use in the third position depends on the strand on which the gene is located. This is because Chargaff's Rule only applies to double-stranded DNA, due to the complementary base pairing that occurs between A-T and C-G. Eventhough the DNA is single stranded ?! Each A pairs with a T and each G pairs with a C, making their molar ratios equal. This is a result of complementary base pairing between single strands of DNA in a helix. Still have questions?
