Why is Taq polymerase used more commonly in PCR than DNA polymerase I from E. coli? 1. Taq polymerase remains active during the high heat denaturation step unlike DNA polymerase I 2.Taq polymerase is less expensive than DNA polymerase I 3.Taq polymerase must be added after each deanturation step unlike DNA polymerase I

In one of Mendel’s pea plants, seed shape and color are controlled by genes located on separate chromosomes where the round shape allele is dominant over wrinkled and the yellow seed color allele is dominant over green. After performing a dihybrid cross (F1 heterozygous at both genes) you observed 360 round, yellow; 115 round, green; 85 wrinkled, yellow; and 20 wrinkled, green F2 plants. If these traits were controlled by two independent genes with two alleles at each gene, would you reject your null hypothesis (that traits are controlled by two independent genes, two alleles at each gene, etc.) based on Table 3.2?

Gametes typically possess only one copy of each chromosome and are said to exist in a __________ state.

DNA migrates toward which pole during gel electrophoresis?

A researcher studied five independently assorting genes in a plant. Each gene has a dominant and recessive allele: ‘R’ black stem, ‘r’ red stem; ‘D’ tall plant, ‘d’ dwarf plant; ‘C’ full pod, ‘c’ constricted pod; ‘O’ round fruit, ‘o’ oval fruit; ‘H’ hairless leaves, ‘h’ hairy leaves. If you crossed two plants that were heterozygous at all genes (‘RrDdCcOoHh’) with each other, what proportion of the offspring do you expect to have the same genotype as the parental plants?

This man ran a privately funded project that was similar to the federally funded Human Genome Project, and greatly catalyzed the completion of the Human Genome Project in 2003.

The provided pedigree shows the inheritance of a recessive trait (‘a’). Unless there is evidence to the contrary, assume the individuals that have married into the family do not carry the recessive allele. What is the probability that the offspring of the following mating will show the trait: (‘a’) III – 7 x III – 16?

Information from RNA molecules is transferred to proteins during which process?

Nucleotides are composed of which of the following?

Chromosomes that exist as members of a pair and have the same genetic makeup are known as:
