1.
Of the following, choose those that are accurate concerning the general concepts of chapters 5 and 6
A) quality studying daily is the best method to have accurate recall on the exams
B) it is a great idea to study all of the questions in the PPTs, the study questions in the textbook, and any questions prompted in the textbook readings
C) sharing questions, answers and ideas in the study lounge is a bad idea
D) since the exams are cumulative it is pointless to continue to study previous chapter study questions and ppt review questions
E) it is a great idea to study the homework reviews thoroughly, knowing why a correct answer is correct, and why an incorrect answer is incorrect
Points Earned:
1.0/1.0

2.
Of the following options choose those that are accurate concerning the topic of antigens and antibodies
A) they are unimportant factors concerning blood transfusions
B) in gene therapy for cancer, the new gene spliced in will generate a protein (tumor antigen) which the immune system will use to identify/target the cancerous cells in the patient's body
C) antibodies of the donor are what cause coagulation in the case of a botched (incorrect) blood transfusion
D) antigens are surface protein markers on all cells (including bacteria) which allow the immune cells to determine self from non-self
E) antibodies locate foreign (bad) antigens, tagging them for destruction
Points Earned:
0.7/1.0

3.
Of the following options choose those that are accurate concerning the topic of protein synthesis

4.
Of the following options mark those that are accurate concerning the topic of cancer

Points Earned:
0.5/1.0

5.
Of the following options mark those that are accurate concerning the topic of meiosis
A) the gonads only undergo meiosis not mitosis
B) S phase doesn't have to take place before meiosis
C) meiosis takes place in the gonads
D) cancer is due to mistakes in meiosis

Points Earned:
0.5/1.0

6.
Of the following options mark those that are accurate concerning the topic of DNA replication
A) ligase unzips the double helix so that it can be copied/replicated
B) DNA polymerase adds nucleotides to the parent DNA strand (building the daughter copied strand of DNA)
C) A goes with T, and G goes with C
D) helicase links the double helix back together
E) DNA replication takes place in the nucleus where the DNA resides

Feedback: Remember to look up and study why the correct options are correct and the incorrect options are incorrect
Points Earned:
0.7/1.0

7.
Of the following options mark those that are accurate concerning the topic of mitosis
A) the copy of a chromosome that is synthesized during S phase, is called a chromatid
B) during metaphase the centriole spindle attaches at the centromere to pull apart the chromosome from its chromatid
C) healthy humans have 23 chromosomes
D) telophase is when the chromosomes are at the end - furthest point, in each of their potentially new cells (not yet divided)
E) in mitosis it is expected that the division will lead to

Cells: The Living Units Cellular Basis of Life 1. A cell is the basic structural and functional unit of living organisms. They range from single-celled “generalists”, like amoebas, to complex multi-cellular organisms such as humans. 2. The majority of cells consist of the same general parts. A generalized cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. The membrane separates a cell from its surroundings and decides what comes in…
