QUESTION 1
How is a bone marrow transplant able to treat someone with leukemia?
The donor blood contains antibodies that destroy cancer cells
Donor blood contains stem cells that regenerate cells in the immune system
Bone marrow contains induced pluripotent stem cells that turn into red blood cells
Bone marrow contains tumor supressor genes that slow down leukemia growth
Bone marrow contains pluripotent human embryonic stem cells
1.2 points
QUESTION 2
What would happen if siRNAs designed to target mRNA from an oncogene were introduced into cancer cells?
Increased genomic instability would result from adding foreign nucleic acids
New mutations would arise in the oncogene
The oncogene would be converted back into a proto-oncogene
The siRNAs would compete with the oncogene's active site
Production of the oncogene protein would decrease
1.2 points
QUESTION 3
What is the purpose of chromatin-remodeling enzymes in human cells?
The enzymes control the rate of translation of an mRNA transcript
The enzymes add phosphate or methyl groups to histone tails
The enzymes slide nucleosomes farther apart or closer to each other
The enzymes send damaged proteins to the proteasome for degradation
The enzymes cause DNA looping to occur
1.2 points
QUESTION 4
If you wanted to resurrect the mammoth, how would you do it?
Use somatic cell nuclear transfer to insert the mammoth genome into the egg of an elephant
Use transcription factors to re-program adult cells from elephants into mammoth cells
Change the gene expression patterns of elephants to increase production of mammoth genes
Use siRNAs to decrease expression of elephant-specific genes in an elephant embryo
1.2 points
QUESTION 5
How is eukaryotic transcription initiated?
RNA polymerase is recruited to the start codon by transcription factors
RNA polymerase begins transcription at the enhancer sequence
RNA polymerase is activated by binding to GTP
An initiator tRNA binds to the ribosome
A complex of proteins forms at the promoter of a gene
