Topic 5 gene to protein learning outcomes 1. 3 parts of nucleotide? a. Phosphate group b. Deoxyribose sugar group c. Nitrogen-containing base 2. Purines vs pyrimidines? a. Purines= guanine adenine. Double ring. b. Pyrimidines= cytosine, uracil (RNA), thymine, (DNA). Single ring 3. DNA structure? a. Double helix b. Antiparallel strands (5’ & 3’) strands run side by side but in opposite directions c. Negatively charged phosphate groups face out of double helix (makes DNA hydrophilic overall) d. PICTURE OF DNA BE ABLE TO KNOW PARTS. BIG MODEL. 4. How does complementary base pairing involve nitrogenous bases work? a. Purines & pyrimidines always pair b. Must have same number hydrogen bonds c. Thymine with adenine (2) d. Cytosine with guanine (3) 5. Differences between DNA & RNA? a. DNA= double stranded. Sugar is deoxyribose. Thymine(has H3C attached to C). Predominantly in nucleus. One type. Has H in bottom position. b. RNA= single stranded. Sugar is ribose. Uracil(has H attached to C). Mainly in nucleus & cytoplasm. More than one type (mRNA, tRNA, rRNA, snRNA, etc.). OH in bottom position 6. Origin of replication a. DNA sequence where replication is initiated b. A bubble is formed. Each bubble has two replication forks 7. Explain process of origin of replication? a. Replication begins at specific sites where 2 parental strands separate and form replication bubbles b. The bubbles expand laterally, as DNA replication proceeds in both directions c. Eventually, the replication bubbles fuse, and synthesis of the daughter strands is complete 8. # of origins of replication in bacterial chromosome vs eukaryotic chromosome? a. Bacterial: 1 origin. Replication goes 5’-3’ in both directions.

    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.
