Question

when a stem cell differentiates and changes in size and shape, specific genes are being (1 point) spliced. transcribed. copied. expressed.

Explanation:

Cell differentiation involves the activation of specific genes. Gene expression refers to the process by which information from a gene is used in the synthesis of a functional gene product (such as a protein). When a stem cell differentiates (changes in size, shape, and function), it is because specific genes are being expressed. Gene splicing is part of RNA processing. Transcription is the first step in gene expression (making RNA from DNA), but the overall process of the cell changing as a result of using gene - derived information is gene expression. Copying (DNA replication) occurs during cell division for growth and repair, not directly for differentiation.

Answer:

expressed.
