Eukaryotes have operons.

From the previous question of the martian family, what is/are the genotype(s) of the mother and brother’s mother?   (Here’s the question again so that you don’t have to go back: A recently found martian family is under study. According to early studies, it was found that D (dextral) is dominant to d (sinistral). The mother and her brother, both have genotype Dd and are sinistral. The father of the family (not their father, but the mother’s husband) is dextral, with the genotype dd. All of their offspring are dextral. )

What is the probability that from the cross Aa Bb Cc dd Ee x Aa bb Cc dd Ee you will produce Aa Bb Cc Dd Ee?   

Neurofibromatosis is an autosomal dominant disease. If one of the parents is homozygous dominant and the other is homozygous recessive, what is the probability that their offspring will not develop the condition? (assume 100% penetrance and complete dominance)

In mature mRNA exons are noncoding regions that are spliced out. T/F

In female mammals, the X-chromosome is inactivated by the Xist gene.

A heart muscle cell transcribes and translates the same genes as a cell in your pancreas.

How is a synchondrosis formed?
