Introduction to Biochemistry Discussion

SCI260 – Introduction to Biochemistry Lesson #9 (1) Which of the double-stranded DNA sequences below will require more heat to separate the two strands (select Option A or Option B)? (2) Why is more heat is required to separate the strands? Option A 5’-GGACTCCCGGGTGAG-3’ 3’-CCTGAGGGCCCACTC-5’ Option B 5’-AACTGTTTAAAGACA-3’ 3’-TTGACAAATTTCTGT-5’ (3) What will be the mRNA sequence that is produced during the transcription of the DNA sequence below? Hint: As we discussed in class, there is a slight difference in the nucleotides used in DNA vs RNA. 5’-ACGTCAGGTTTCCGT-3’ (4) Based on what was discussed in Lecture 9, name four (4) enzymes/proteins that play a role in human DNA replication, and briefly describe the specific role each plays during human DNA replication. You may use the internet and/or your textbook to assist you. Each answer is worth 25 points (be sure to answer ALL four questions) giving you a maximum total of 100 points for this assignment. Please DO NOT copy your answers directly from the textbook or the internet.

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
