- Here are schematic diagrams of mutant Drosophila larvae. The left side of each pair shows a wild-type larva, with gray boxes showing the sections that are missing in the mutant larva. Which type of gene is defective in each larva: a gap gene, a pair-rule gene, or a segment-polarity gene?arrow_forwardExplain the likely evolutionary origin of mitochondrial and chloroplast genomes. How have the sizes of the mitochondrial and chloroplast genomes changed since their origin? How has thisoccurred?arrow_forwardTo understand the genetic basis of locomotion in the diploid nematode Caenorhabditis elegans, recessive mutations were obtained, all making the worm “wiggle” ineffectually instead of moving with its usual smooth gliding motion. These mutations presumably affect the nervous or muscle systems. Twelve homozygous mutants were intercrossed, and the F1 hybrids were examined to see if they wiggled. The results were as follows, where a plus sign means that the F1 hybrid was wild type (gliding) and “w” means that the hybrid wiggled.a. Explain what this experiment was designed to test. b. Use this reasoning to assign genotypes to all 12 mutants. c. Explain why the phenotype of the F1 hybrids between mutants 1 and 2 differed from that of the hybrids between mutants 1 and 5arrow_forward
- What are the steps in the life of a nuclear-encoded mitochondrial precursorarrow_forwardThe mitochondrial genome of Chlamydomonas contains the lowest number of genes, 12, of all the species of green algae. However, only 7 proteins are produced inside these mitochondria. Which of the following statements is the best explanation for why only 7 proteins are made from the 12 genes In Chlamydomonas mitochondria? OA Five of the genes are redundant; another copy is expressed from the nuclear genome.. OB. Five of the genes are nonfunctional "pseudogenes". OC Five of the genes are transcribed, but not translated. OD. Five of the genes are coding for proteins that are translated in the cytoplasm. Reset Selectionarrow_forwardLet's say that an experiment resulted in the production of several unattached kinetochores. What effect, if any, would this have on (i) the duration (length) of the mitotic phase, (ii) the timing of cyclin B’s appearance or disappearance, and (iii) the period of time for which MPF is active? Briefly explain your reasoning.arrow_forward
- Segregation and independent assortment are LEAST likely to be exhibited by genes in a) Escherichia coli b) Arabidopsis thaliana c) Caenorhabditis elegans d) Drosophila melanogaster e) Neurospora crassaarrow_forwardMap distances were determined for four differentgenes (MAT, HIS4, THR4, and LEU2) on chromosome III of the yeast Saccharomyces cerevisiae:HIS4 ↔ MAT 37 cMTHR4 ↔ LEU2 35 cMLEU2 ↔ HIS4 23 cMMAT ↔ LEU2 16 cMMAT ↔ THR4 20 cMWhat is the order of genes on the chromosome?arrow_forwardHumans and many other complex organisms are diploid, possessing two sets of genes, one inherited from the mother and one from the father. However, a number of eukaryotic organisms spend most of their life cycles in a haploid state. Many of these eukaryotes, such as Neurospora and yeast, still undergo meiosis and sexual reproduction, but most of the cells that make up the organism are haploid. Considering that haploid organisms are fully capable of sexual reproduction and generating genetic variation, why are most complex eukaryotes diploid? In other words, what might be the evolutionary advantage of existing in a diploid state instead of a haploid state? And why might a few organisms, such as Neurospora and yeast, exist as haploids?arrow_forward
- How much is the weight of 1 copy of the human haploid genome ?arrow_forwardIf you expose a culture of human cells (for example,HeLa cells) to 3H-thymidine during S phase, howwould the radioactivity be distributed over a pair ofhomologous chromosomes at metaphase? Would theradioactivity be in (a) one chromatid of one homolog,(b) both chromatids of one homolog, (c) one chromatid each of both homologs, (d) both chromatids ofboth homologs, or (e) some other pattern? Choose thecorrect answer and explain your reasoning.arrow_forwardThere are 40 chromosomes in somatic cells of the house mouse. (a) How many chromosomes does a mouse receives from its father? (b) How many autosomes are present in a mouse gamete? (c) How many sex chromosomes are in a mouse ovum? (d) How many autosomes are in somatic cells of a female?arrow_forward
