Detailed explanation-1: -Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins.
Detailed explanation-2: -Southern blotting (a technique developed by E. M. Southern) is widely used for detection of specific genes in cellular DNA (Figure 3.29).
Detailed explanation-3: -The five-carbon sugar in DNA is called deoxyribose, while in RNA, the sugar is ribose. These two are very similar in structure, with just one difference: the second carbon of ribose bears a hydroxyl group, while the equivalent carbon of deoxyribose has a hydrogen instead.
Detailed explanation-4: -These form long chains of nucleotides called nucleic acids, such as DNA or RNA. DNA stores genetic information, while RNA is capable of transmitting and executing genetic information through the use of specialized types of RNA, namely mRNA, tRNA, and rRNA.
