Which of the following occurs in meiosis I?

Ribosomes “read” the information in a processed strand of mRNA and use it to build an amino acid chain (polypeptide), which will eventually become all or part of a protein. This process is called

When an insertion or deletion of a nucleotide occurs during DNA replication, a ribosome may “read” a different codon at that location when gene is transcribed into RNA.  This is called a(n)

The specific identity of a nucleotide (that is, its name or letter—A, T, C, G, or U) is determined by its

“Gene expression” means that

Crossing over actually occurs in

 If one parent is heterozygous for type A blood, and the other parent is heterozygous for type B blood, the probability of producing a child with type O blood is

When one gene influences or modifies the phenotypic expression of another gene, such as with coat color in Laborador retrievers (i.e. one gene codes for pigment deposition, the other gene controls how much), those genes are said to be

When tumor cells move from one part of the body and initiate abnormal growth in anotherpart of the body, the new tumor cells are called

When Mendel allowed the F1 generation to self-fertilize, the offspring in the F2 generation were
