Which approach could be used to investigate distinctions between a muscle cell and a bone cell?
A) gene expression profiling
B) DNA variation screening
C) microarray comparative genomic hybridization
D) transcription-mediated amplification
E) PCR

Question

Quizplus · Accepted Answer

Gene expression profiling can be used to investigate distinctions between a muscle cell and a bone cell, as the different functions of these cells are primarily due to differences in gene expression. By comparing the patterns of gene expression in muscle cells and bone cells, researchers can identify the genes and pathways that are specific to each cell type, and gain insight into how these cells function and develop.

B) DNA variation screening and C) microarray comparative genomic hybridization are less likely to be effective approaches for investigating distinctions between a muscle cell and a bone cell, as these techniques are more focused on identifying genetic differences between different individuals or populations, rather than between different cell types.

D) Transcription-mediated amplification and E) PCR are techniques used to detect and amplify specific RNA or DNA sequences, respectively, and may be useful for examining individual genes or gene expression patterns within muscle cells or bone cells. However, they are less effective for looking at global differences in gene expression and function between cell types.
