1.) Differentiate DNA and RNA in terms of structure and composition
DNA is known as the blueprint of biological guidelines that a living organism must follow to exist and remain functional. RNA on the other hand, helps carry out this blueprint's guidelines. Of the two, RNA is more versatile than DNA because it is capable of performing numerous, diverse tasks in an organism, but DNA is more stable and holds more complex information for longer periods of time. | DNA | RNA | Structural Name: | Deoxyribonucleic Acid | Ribonucleic Acid | Definition | A nucleic acid that contains the genetic instructions used in the development and functioning of all modern living organisms. DNA's genes are expressed, or manifested, through the proteins that its nucleotides produce with the help of RNA. | The information found in DNA determines which traits are to be created, activated, or deactivated, while the various forms of RNA do the work. | Function: | Medium of long-term storage and transmission of genetic information. | Transfer the genetic code needed for the creation of proteins from the nucleus to the ribosome. This process prevents the DNA from having to leave the nucleus, so it stays safe. Without RNA, proteins could never be made. | Structure: | Typically a double- stranded molecule with a long chain of nucleotides. | A single-stranded molecule in most of its biological roles and has a shorter chain of nucleotides. | Bases/Sugars: | Long polymer with a deoxyribose and phosphate backbone and four different bases: adenine, guanine, cytosine and thymine. | Shorter polymer with a ribose and phosphate backbone and four different bases: adenine, guanine, cytosine, and uracil. | Base Pairing: | A-T (Adenine-Thymine), G-C (Guanine-Cytosine) | A-U…...
