According to a database kept by the HUGO Gene Nomenclature Committee,there are currently six genes in the human genome for different variants of the protein collagen IV.Assuming that all these genes are derived from an ancestral gene,the most precise term for these genes would be ________.
A) homeotic
B) paralogous
C) transcription factors
D) structural
E) orthologous

Question

Quizplus · Accepted Answer

Paralogous genes are genes that arise by duplication from a common ancestral gene, and the six genes in the human genome for collagen IV variants fit this description. Homeotic genes control the development of body structures, transcription factors regulate the expression of other genes, and structural genes code for proteins that form structural components of cells, tissues, and organs. Orthologous genes are genes in different species that are evolutionarily related and have a common ancestor.
