Plants are more easily manipulated by genetic engineering than are animals because:

1. Plant genes do not contain introns

2. More vectors are available to transfer rDNA into plant cells

3. Totipotency is a feature generally associated with plant cells and not with animal cells

4. Genes can be inserted into animal cells by microinjection.

Difficulty Level:


If gene isolate from marrow cells producing ADA is introduced into cells at early embryonic stage, it could be a permanant cure of ADA deficiency because the early embryonic cells :

1. Are more differentiated than the later stage cells

2. Are constantly dividing and do not get differentiated 

3. Are easy to manipulate than the later stage cells

4. Are virtually immortal
