The developmental process in which certain cells produce multiple copies of a gene by selective replication, thus allowing for increased synthesis of the gene product. Compare with nuclear equivalence and genomic rearrangement.

Specific Protein

A particular protein with a unique function or role, often distinguished by its structure and activity within biological processes.

Transcription

The process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA), initiating protein synthesis.

Methyl Groups

Chemical groups consisting of one carbon atom bonded to three hydrogen atoms (-CH3), often involved in modifying DNA and proteins to regulate gene expression and protein function.
