This question is easy…. think about complementary base pairing!  If a sample of double-stranded DNA contains 20% thymine (T), calculate the percentages of A, C, and G.  Approximately what percent of the nucleotides in this sample will be guanine (G)?  

  CH14 vocabulary (part 2)… match the term to the correct definition (hint: copied primarily from quizlets!)  

  CH13 vocabulary (part 2)… match the term to the correct definition (hint: copied directly from quizlets!)  

Use the figure to answer the following question (hint: pay attention to orientation)     Referring to the figure, what bases will be added as DNA REPLICATION proceeds on the bottom strand?  

  Easy!!!!  According to the central dogma (the more simplified version!!!!), what is the intermediate molecule involved in the flow of information in a cell (goes from the nucleus out to the cytoplasm) that should go in the blank?                       DNA → ________ → PROTEIN  

  Regulation of gene expression is primarily done at the pre-transcriptional (i.e. chromatin modification) and/or transcriptional level.   Post-transcriptional mechanisms typically only play “supporting” roles.  

Which of the following is an inherited disease characterized by destruction of ACh-secreting and GABA-secreting neurons in the basal nuclei causing difficulty controlling movements?

The ________ tract provides subconscious regulation of distal parts of limbs (Upper limb) muscle tone and precise movement and is part of the ________ pathway.

Descending Motor Tracts in the Spinal Cord: Please match the number with the correct term used to identify the motor pathways. 

  Nothing screams “big picture” like this next question and, if you don’t get goose bumps reading/answering it, there’s something very wrong with you.     Once researchers identified DNA as the molecule responsible for transmitting heritable traits, they asked how information was transferred from the DNA in the nucleus to the site of protein synthesis in the cytoplasm. Which of the following statements correctly describes the mechanism of information transfer that accomplishes this task in eukaryotes (like us!)?
