DNA stands for deoxyribonucleic acid . RNA is ribonucleic acid . Both DNA and RNA carry genetic information, they have several differences between them. In this essay I will compare some of the differences between DNA and RNA. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA is a double stranded molecule while RNA is a single stranded molecule. There is a difference in function between the two. DNA’s function is long-term storage of genetic information; transmission of genetic information to make other cells and new organisms. While on the other hand the function of RNA is to transfer the genetic code from the nucleus to the ribosomes to make proteins. RNA is used to transmit genetic information in some organisms and may have been the molecule used to store genetic blueprints in primitive organisms. DNA is a B-form double helix. DNA is a double-stranded molecule consisting of a long chain of nucleotides. RNA is an A-form helix and usually is a single-

Unformatted text preview: strand helix consisting of shorter chains of nucleotides Summing up the two DNA carries the genetic information of a cell and consists of thousands of genes. Each gene serves as a recipe on how to build a protein molecule. Proteins perform important tasks for the cell functions or serve as building blocks. The flow of information from the genes determines the protein composition and thereby the functions of the cell. DNA never leaves the nucleus, instead the genetic code (the genes) is copied into RNA which then in turn is decoded (translated) into proteins in the cytoplasm. Humans did not evolve with one central repository of DNA because the body would not be able to replicate cells to heal, to perform regular functions to keep itself sustaining. If you cut yourself it would take too much time to communicate what needed to be done, your body would never heal. ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
