Concerning disorders resulting from unstable expansion of tandem oligonucleotide repeats, which, if any of the following statements is false.

A) The expansions can occur in coding DNA in some cases, and in noncoding DNA in other cases.

B) The repeats are of a variable number of nucleotides (from three to six) in both coding DNA and noncoding DNA.

C) The expansions in noncoding DNA are generally much larger in size than those in coding DNA.

D) The expanded arrays in noncoding DNA always result in loss of function of the host gene or of a neighboring gene.

In very dry soils, the water potential (Yw) may fall below what is called the permanent wilting point, the water potential of the soil is so low that plants cannot regain turgor pressure even if all water loss through transpiration ceases. This means that

a) The hydraulic conductivity decreases drastically 

b) The water potential of the soil (Yw) is less than or equal to the osmotic potential (Ys ) of the plant

c) The water potential of the soil (Yw) is more than the osmotic potential (Ys) of the plant

d) cell osmotic potential (Ys) varies with plant species, the permanent wilting point is clearly not a unique property of the soil, it depends on the plant species

In normal cells, FOS and MYC mRNAs and the proteins they encode are intrinsically unstable and degrade rapidly after the genes are transcribed, Conversion of the MYC proto-oncogene into an oncogene can occur by different mechanisms, Other members of this protein set include MAD, MAX, and MNT, choose incorrect statement regarding this,
