Most amino acids are coded for, by more than one codon. Consequently the genetic code is ............. a) degenerate b) conservative c) semi-conservative d) carcinogenic

Many oncogenes result from mutations that cause excessive expression of a protein in cells where it is normally not expressed or is expressed at inappropriate times during development. This type of mutation can be described as ________. A) amorphic B) hypomorphic C)hypermorphic D) neomorphic E) dominant negative

The protein neuroD is a critical human protein translated in the brain during development. The protein is 357 amino acids long. What is the length of the human neuroD *gene* sequence? a)357 nucleotides b)1071 nucleotides c)119 nucleotides d)You cannot determine the length of the gene from this information alone.

Which is the expected outcome following the deacetylation of histones? a) Coiling of chromatin, preventing it from being accessed by transcriptional machinery b) Coiling of chromatin, allowing it to be accessed by transcriptional machinery c) Uncoiling of chromatin, preventing it from being accessed by transcriptional machinery d) Uncoiling of chromatin, allowing it to be accessed by transcriptional machinery

All of the following are involved in transcription excepta) polymerase.          b) primer.            c) promoter.d) sigma factor.        e) uracil.

How are the genes in the beta-globin locus different from each other? A) They have different evolutionary origins, from different ancestral genes. B) They have different sequences and locations on the chromosome. (C) They are expressed at different times in developmnent. (D) Some are expressed in all cells; some are expressed only in red blood cells. E) They are dispersed on on different chromosomes.
