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)

From #37, this means that one of the template strands can be replicated continuously, while the other template strand must be replicated discontinuously in an alternating series of primers and short sequences called Okazaki fragments.  This discontinuous replication happens on the

Be sure to answer all of the questions below in the single text box provided. From the dihybrid cross above, suppose that a researcher wanted to determine whether smurf color and smurf breath are independently inherited (assort independently) or are genetically linked.  a) How would the researcher state his/her hypothesis, as it relates to Mendel’s law and observed vs. expected numbers, before conducting a Chi-square analysis? The null (Ho) would state that: The alternative (Ha) would state that:   b) Suppose that after counting the number of observed offspring, the researcher calculated a Chi-square value of 11.35.  Using the table below, what would the p-value for this analysis be?  (Hint: the df, or degrees of freedom here, would be 3.)   c) Based on the p-value you got from b), are the traits inherited independently (do they follow Mendel’s Law of Independent Assortment), or are they linked?  (Remember: the “cutoff” for statistical significance is a p-value of 0.05)

The alleles for type A blood and type B blood are said to be _______ over the allele for type O blood.

 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 two or more genes are carried together during crossing over in meiosis, such that one phenotype is usually associated with another (e.g. eye color and wing length in fruit flies), those genes are said to be
