Nucleic Acids Store and transmit hereditary information Genes are units of inheritance. Genes have a specific sequence of nucleotides. The sequence is where the information comes from for the sequence of amino acids [in a protein?]. Each gene has the information for ONE protein Sequence of nucleotides in a gene determines primary structure of a protein

Two Types of Nucleic Acids Deoxyribonucleic acid (DNA) The structure of DNA contains the information that programs the cell Function is to just hold DNA and pass it on Ribonucleic acid (RNA) mRNA : messenger RNA (from DNA to ribosome) rRNA : ribosomal RNA (what makes up the ribosome) tRNA : transfer RNA (transfers amino acids; also known as the “interpreter”)

    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.
