Which of the following best describes the role IκBα phosphorylation plays in the signaling pathway and what the modification of IκBα does? IκBα activates the transcription factor. Phosphorylation of IκBα leads to phosphorylation and activation of the transcription factor.
IκBα inhibits the activation of the transcription factor. Phosphorylation of IκBα signals for the nuclear transcription factor to transcribe DNA.
IκBα inhibits the translocation of the transcription factor. Phosphorylation of IκBα signals for IκBα degradation and allows the transcription factor to enter the nucleus.
IκBα activates the translocation of the transcription factor. Phosphorylation of IκBα leads to phosphorylation of the transcription factor, which allows the transcription factor to enter the nucleus.

Suppose a point mutation, such as a change from an adenine to a guanine, occurs in the genome of a human sperm cell. the mutation could occur in any region of a gene. the effect of the mutation on the phenotype of the offspring will be determined by where the mutation occurs and its effect on the final gene product. in which of the following scenarios could the mutation alter the phenotype of the offspring? select all of the scenarios that apply the mutation occurs in the promoter and affects the rate of gene transcription. the mutation results in a new, dominant allele the mutation occurs in a portion of an intron not responsible for exon splicing the mutation occurs in a gene that controls development and alters differentiation of a cell type during development. the mutation occurs in a codon and alters the function of the final protein e mutation occurs in a codon, and the amino acid sequence of the final protein is unchanged.
