Some viruses have RNA but no DNA. This would indicate that– (1) these viruses cannot replicate (2) these viruses have no heritable information (3) RNA transmits the hereditary information in these viruses (4) their nucleic acids can be crystallised Answer : these viruses have no heritable information...
The structure of DNA is a double helix formed by two strands of DNA sequence. This sequence consists of 4 different nucleotides- Adenine, Thymine, Cytosine and Guanine. How do the nucleotides on one strand interact with the nucleotides on the second strand to maintain the helical shape of DNA? Answer : Complementary Base Pairing. Adenine complementary base pairs with Thymine and Guanine complementary base pairs with Cytosine....
