The deflection of pitch angle between two successive steps (rungs) of DNA is

A terminator codon which is called amber is

The nucleotide sequence on antisense strand of DNA which is transcribed as codon that specifies the amino acid serine is

What will be the codons in m-RNA if the DNA codes are ATG-CAG?

Out of A-T, G-C pairing, bases of DNA may exist in alternate valency state owing to arrangement called as

When DNA replication starts

From the given genetic code table, find out the 1$$^s$$$$^t$$ and last amino acid formed from the mRNA associated with the given DNA template strand.

E. coli bacteria grew in a nutrient solution containing a heavy, stable isotope of nitrogen, $$^{15 }N$$. It is then transferred to a medium with the more common light isotope of nitrogen. Then DNA from the cells was extracted and subjected to density centrifugation. The strain of E. coli used to divides once every 20 minutes. The results are illustrated below, the heaviest DNA is extracted from the cells at

An error in the polypeptide chain produced from DNA sequence is not always the result of mutation. The best explanation for this is that

Which of the following is true about codon?
