a few questions on biology?

True or False:

1. If an organism is heterozygous for a particular gene, the two different alleles will be seperated during anaphase II of meiosis, ssuming that no crossing over has occurred

2. The replications of a DNA molecule results in four copies of the same gene

3. The TATA box in eukaryotes helps to ensure transcription

4. To produce a recombinant plasmid, the plasmid and the foreign DNA are cut with a different restriction enzyme.

5. If a cat has orange and black spots, it is homozygous for the alleles on the X chromosome that code for spot color


please help? thank you:)
 
4) False, they need the same restriction enzyme or else they won't fit with each other
