What would be the consequences of the following? (a) a mutation of a promoter sequence such that the promoter is deleted.(b) a mutation of the gene that encodes rna polymerase such that the polymerase is not made.(c) deletion of intron consensus sequences from a gene.

Answer A)

The gene would not be transcribed. This is because the gene transcribing machinery would not be activated if the promoter sequence is not recognized. Transcription will not start.

Answer B)

The gene would not be transcribed. This will result in no RNA polymerase being formed. Hence, transcription and translation will not occur.

Answer C)

The mRNA would contain intron sequences, which would be translated into extra amino acids in the protein. A non- functional protein would be made.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
