Sheet1 Page 1 - sequence of 3 nucleotides = 1 codon - 1 codon codes for one amino acid - more than enough for the 20 amino acids - 1 to 6 different codons for same amino acid - also have start codon and 3 stop codons - so code for a protein will have x + 2 codons - tables transcribe portion of DNA to protein production site (ribosomes) DNAComp StrandmRNAtRNA G CCG ATcode forUA (GAC is anticodon) CGamino acidGC Steps in Protein Production - called translation - process of extending the being-built protein is called elongation 8. After a codon is read and its amino acid is fitted into the proper sequence, the mRNA moves to bring its codon onto the ribo 9. After protein is completed, it breaks away - called termination Further INFO on genetic material Terms -- may be intermeshed with exons Steps in Transcription 1.RNA polymerase finds appropriate promoter and opens up just that part of the DNA 2.mRNA is transcribed between promoter and terminator 3.introns are cut out leaving just the functional part of the gene (the extrons)

    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.
