Which of the following can be a negative number in testing the mean of a sample?
Genetically Similar Cells
Cells that have nearly identical genetic material, often as a result of replication in processes such as mitosis.
Homeotic Genes
Genes that control the development of anatomical structures in organisms, ensuring parts develop in the correct locations.
Transcription Factors
Proteins that regulate gene expression by binding to DNA sequences, thereby controlling the transfer of genetic information from DNA to mRNA.
Adult Stem Cells
Cells derived from body tissues that can differentiate into some specific cell types (e.g., blood cells, neuronal cells, or muscle cells), but not all types of cells found in an organism. See pluripotent stem cells and totipotent stem cells.
