Steps Of Dna Fingerprinting Ncert Biology Class 12 Mole Molecular basis of inheritance 6.1 the dna 6.2 the search for genetic material 6.3 rna world 6.4 replication 6.5 transcription 6.6 genetic code 6.7 translation 6.8 regulation of gene expression 6.9 human genome pr oject 6.10 dna fingerprinting in the previous chapter , you have lear nt the inheritance patterns and the genetic basis of such. Following are the steps involved in dna fingerprinting: isolating the dna. digesting the dna with the help of restriction endonuclease enzymes. separating the digested fragments as per the fragment size by the process of electrophoresis. blotting the separated fragments onto synthetic membranes like nylon.
Molecular Basis Of Inheritance Notes Class 12 Part 10 Dna Definition of dna fingerprinting. "dna fingerprinting is a procedure that shows the hereditary cosmetics of living things. it is a strategy for finding the distinction between the satellite dna areas in the genome." dna profiling, dna testing, dna examination, genetic profile, dna distinguishing proof, genetic fingerprinting, and genetic. Ans: nitrogenous bases – adenine, uracil and cytosine, thymine; nucleosides – cytidine, guanosine. 2. if a double stranded dna has 20 per cent of cytosine, calculate the per cent of adenine in the dna. ans: in a dna molecule, the number of cytosine molecule is equal to guanine molecules & the number of adenine molecules are equal to thymine. Access answers to biology ncert chapter 6 – molecular basis of inheritance. 1. group the following as nitrogenous bases and nucleosides: adenine, cytidine, thymine, guanosine, uracil and cytosine. solution: following is the grouping: nitrogenous base. nucleosides. Rna is a vital molecule with a long chain of nucleotides. it is a first genetic material. a nucleotide chain comprises a phosphate, a ribose sugar, and nitrogenous base. rna acts as a catalyst and as a genetic material. rna is a non hereditary nucleic acid except in some viruses (retro viruses).
