The method of asexual reproduction by prokaryotic cells.

In pea plants, tall (T) is dominant to short (t).  Green seed (G) is dominant to yellow (g).  If two heterozygous tall, green seeded plants are crossed, what proportion of their offspring will be short, yellow seeded plants?

Domain ____________ includes Kingdom ________________, Kingdom _______________, and Kingdom Plantae.

In tomato plants, purple stems (P) are dominant to green (p), and red fruit (R)  is dominant to yellow fruit (r).  If a homozygous purple-stemmed, yellow-fruited plant is crossed with a homozygous green-stemmed, red fruited plant, what proportion of the first filial (F1) generation will have purple stems and red fruit?  

The main product of the Calvin cycle is:

In a DNA double helix, phosphate groups have covalent phosphodiester bonds with:
