Transcription … make a protein from converting DNA to RNA (protein synthesis) DNA strand .. C T G T A C G (three nucleotides =triplets) mRNA = G A C A U G C (three nucleotides = CODON) heading to rRNA still in nucleus – going to ribosome … translation rRNA comrprised of two subunits. tRNA = heading to rRNA, anticodon C U G T A C G TRANSLATION – nucleotide to protein dehydration syntheis enzyme = polymerase protein getting out of cell – golgi complex- packaged, zoom out of cell membrane, stomach EXOCYTOSIS S phase of cell cycle = replicate DNA , Enzymes = polymerase, ligase HIV INFECTION – RNA virus, retrovirus, ability to build DNA from RNA with reverse transcriptase… DNA insecrts self into YOUR DNA… becomes provirus MEIOSIS- production of gametes… crossing over happens since homologous chromosomes pair = sister chromatid… 4 haploids – genetic variation… more diverse progeny Prophase-homoglous chromosomes pair GENE REGULATION 1.

    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.
