  • Q1
    What is genomics?
    Genomics is an illustration that lists genes and their location on a chromosome.
    Genomics is a genetic marker, a gene or sequence on a chromosome that co-segregates (shows genetic linkage) with a specific trait.
    Genomics is the study of entire genomes, including the complete set of genes, their nucleotide sequence and organization, and their interactions within a species and with other species.
    Genomics is the process of finding the locations of genes on each chromosome.
  • Q2
    Sequencing an individual person's genome ________.
    will not lead to legal issues regarding discrimination and privacy
    is currently impossible
    will not help make informed choices about medical treatment
    helps in predicting faulty genes in diseases
  • Q3
    Genomics can be used in agriculture to do what?
    improve yield
    improve disease resistance
    generate new hybrid strains
    improve yield and resistance and generate hybrids
  • Q4
    What are the uses of metagenomics?
    use in increasing agricultural yields
    testing for multiple drug susceptibility in a population
    identification of biofuels
    identifying new species more rapidly and analyzing the effect of pollutants on the environment
  • Q5
    How can proteomics complement genomics?
    Genomics is responsible to decide the structure of the proteins, and, thereby, the result of proteomic studies.
    The genes are responsible to produce proteins and this implies that proteomics complements genomics.
    The genome is constant but the proteome is dynamic as different tissues possess the same genes but express different genes, thereby complementing genomics.
    The study of genes is incomplete without the study of their respective proteins and thus they complement each other.
  • Q6
    Bioinformatics includes all of the following except:
    using mathematical tools to analyze biological systems
    developing computer-based tools for proteome analysis
    using DNA technology to combine DNA from two different species in a test tube
    using computer software to align DNA sequences
  • Q7
    Two eukaryotic proteins have one domain in common but are otherwise very different. Which of the following processes likely contributed to this similarity?
    exon shuffling
    random point mutations
    alternative splicing
    gene duplication
  • Q8
    Genes important in the embryonic development of animals, such as homeobox-containing genes, have been relatively well-conserved during evolution. What is the best explanation for this phenomenon?
    homeobox-containing genes are located in stable chromosomes
    individuals with changes in homeobox-containing gene sequences are likely to have fewer offspring relative to wildtype individuals
    individuals with changes in homeobox-containing gene sequences are likely to have more offspring relative to wildtype individuals
    homeobox-containing genes do not contain transposons
  • Q9
    The main goal of the Human Genome Project (HGP) was to:
    Identify the unique parts of each person's DNA.
    Determine the entire sequence of human DNA.
    Identify genes responsible for human behavior.
    Identify genes responsible for human diseases.
  • Q10
    The genomes of two unrelated humans are ___% the same.
  • Q11
    What is the general trend of the genome size and number for viruses, bacteria and eukaryotic organisms?
    Genome size and number increases from viruses to bacteria but then decreases to eukaryotes
    There is no relationship across domains when considering genome size and gene number.
    Genome size and number increases from viruses to bacteria to eukaryotes
    Genome size decreases from viruses to bacteria but then increases to eukaryotes
  • Q12
    Within a domain, the general trend of genome size and number is:
    More complex organisms have more genes and larger genomes.
    More complex organisms have more genes and smaller genomes.
    Less complex organisms have fewer genes and smaller genomes.
    There is no trend when considering genome size and gene number within domains.
