Consider the following statements about genetics and choose the CORRECT alternative:
II. House-keeping genes are normally expressed in all cells, being responsible for cellular basal metabolism.
III. When researchers found that the number of protein-coding genes does not show a linear correlation with the complexity of organisms, this contradiction was called the C-value paradox.
IV. When researchers found that the size of protein-coding genes does not show a linear correlation with the number of genes in organisms, this contradiction was called the G-value paradox.
V. Genes from a genome that are shared among other genomes are called conserved.
