Solved by a verified expert:1.1 When comparing normal meiosis in human males and femalesa.) each sperm has 46 chromosomesb.) in most cases each egg and sperm contain single sex chromosomesc.) each egg produced contains one more autosome than a sperm celld.) all sperm contain the same kind and amount of DNAe.) each egg has 12 autosomes1.2 All of the following occur during prometaphase of mitosis in animal cells excepta.) the centrioles move toward opposite poles.b.) the nucleolus can no longer be seen.c.) the nuclear envelope disappears.d.) chromosomes replicate.e.) the spindle is organized.1.3 When studying an inherited phenomenon, a geneticist discovers a phenotypic ratio of 9:3:3:1 among offspring of a given mating. A possible explanation for this is a two locus-two alleles at each locus system that exhibitsa. epistasisb. linkagec. pleiotropyd. independent assortmente. dominancePage Break1.4. In peas, a tall, yellow-seeded plant is crossed with a homozygous short, green-seeded plant and yields 203 tall, green-seeded plants, 199 short, green-seeded plants, 207 tall, yellow-seeded plants, and 192 short, yellow-seeded plants. The most likely genotype of the tall, yellow-seeded parent isa. TtYyb. TTYYc. ttyyd. ttYYe. none of the above1.5. Given an individual who is heterozygous at 5 loci, how many different gametic genotypes are possible?a. 25b. 10c. 15d. 32e. 642.1 Dideoxy nucleoside triphosphate (ddNTP)a. can form a sugar phosphate bond with a new nucleoside triphosphate during DNA synthesisb. has an oxygen at the 3′ carbonc. cannot bind to a growing DNA chaind. has an oxygen at the 2′ carbone. will terminate DNA synthesis when incorporated into a growing DNA strand2.2 The whole-genome shotgun sequencing approach depends primarily ona. rapidly sequencing thousands of small randomly cloned fragmentsb. methodical sequencing a few large cloned fragments of DNAc. sequencing the bacterial chromosome while it is still intactd. all of the abovee. none of the above2.3 TAQ polymerase is so special and useful for PCR becausea. It can replicate DNA faster than any other polymeraseb. It can create amino acid strands complimentary to RNA strandsc. It can synthesize new DNA strands, form a DNA template at high (~ 80C) temperaturesd. It can synthesize new DNA strands, without primerse. It can act as a ligase2.4 In the context of DNA sequencing, what is a contig?a. A set of overlapping DNA fragmentsb. The number of nucleotides per centiMorganc. The amount of DNA sequence that is found in one readd. A mature mRNA in which introns have been removede. Complement and reversed sequences2.5Illumina and 454 sequencing are based ona. sequencing by synthesisb. chain terminationc. nanoporesd. sequencing on chipse. sequencing using chemical degradation
