  • 1

    With the help of this, the causes of genetic disorders were now being traced and defective genes are now detected

    molecular biology

  • 2

    treating genetic disorders called__

    gene therapy

  • 3

    The initial aim was the correction of inherited genetic diseases.

    gene therapy

  • 4

    is when a DNA is introduced into a patient to treat a genetic disease.

    gene therapy

  • 5

    A gene that is inserted directly into a cell usually does not function. Instead, a carrier called a ___ is genetically engineered to deliver the gene.

    vector

  • 6

    Certain __ are often used as vectors because they can deliver the new gene by infecting the cell.

    viruses

  • 7

    ____integrate their genetic material including the new gene into a chromosome in the human cell.

    retroviruses

  • 8

    ___introduce their DNA into the nucleus of the cell, but the DNA is not integrated into a chromosome.

    adenoviruses

  • 9

    ___can be injected or given intravenously (by IV) directly into a specific tissue in the body, where it is taken up by individual cells.

    vector

  • 10

    Types of Gene Therapy:

    1. Somatic gene therapy 2. Germline gene therapy

  • 11

    transfer of a section of DNA to any cell of the body that doesn't produce sperm or eggs.

    Somatic gene therapy

  • 12

    transfer of a section of DNA to cells that produces sperm or eggs.

    Germline gene therapy

  • 13

    Categories of Gene Therapy:

    1. Somatic-Cell gene therapy 2. Germ Line gene therapy 3. Somatic cell enhancement 4. 4. Germ line enhancement.

  • 14

    for the cure and prevention of diseases.

    Somatic-Cell gene therapy

  • 15

    Example: insertion of a DNA sequence into a person's cell to allow production of an enzyme like adenosine deaminase.

    Somatic-Cell gene therapy

  • 16

    🙃🎀💌

    Example: Insertion of an adenosine deaminase sequence into early embryo or reproductive cells, which would affect not only the individual but all of his or her offspring.

  • 17

    Example: Insertion of a DNA sequence to improve memory, increase height, or increase intelligence which would affect only the individual.

    Somatic cell enhancement.

  • 18

    Example: Insertion of a DNA sequence for enhancement into a blastocyst, sperm or egg, which would affect future generation.

    Germ line enhancement

  • 19

    It is designed for diseases caused by loss of function of a gene, introducing extra copies of a normal gene may increase the amount of normal gene product to a level where the normal phenotype is restored.

    Gene augmentation therapy.

  • 20

    This is suitable for the treatment of infectious diseases, cancer and inherited diseases caused by the inappropriate gene activity.

    Gene inhibition therapy.

  • 21

    The aim is to introduce a gene whose product either: inhibits the expression of another gene or interferes with the activity of the product of another gene.

    Gene inhibition therapy.

  • 22

    Genes are directed to the target cells and then expressed so as to cause cell killing.Direct cell killing is possible if the inserted genes are expressed to produce a lethal toxin(suicide gene) or a gene encoding a prodrug is inserted, conferring susceptibility to killing by a subsequently administered drug.

    Gene therapy killing of specific cells.

  • 23

    At present, the type of therapy being undertaken is___

    somatic gene therapy

  • 1

    With the help of this, the causes of genetic disorders were now being traced and defective genes are now detected

    molecular biology

  • 2

    treating genetic disorders called__

    gene therapy

  • 3

    The initial aim was the correction of inherited genetic diseases.

    gene therapy

  • 4

    is when a DNA is introduced into a patient to treat a genetic disease.

    gene therapy

  • 5

    A gene that is inserted directly into a cell usually does not function. Instead, a carrier called a ___ is genetically engineered to deliver the gene.

    vector

  • 6

    Certain __ are often used as vectors because they can deliver the new gene by infecting the cell.

    viruses

  • 7

    ____integrate their genetic material including the new gene into a chromosome in the human cell.

    retroviruses

  • 8

    ___introduce their DNA into the nucleus of the cell, but the DNA is not integrated into a chromosome.

    adenoviruses

  • 9

    ___can be injected or given intravenously (by IV) directly into a specific tissue in the body, where it is taken up by individual cells.

    vector

    Types of Gene Therapy:

    1. Somatic gene therapy 2. Germline gene therapy

  • 11

    transfer of a section of DNA to any cell of the body that doesn't produce sperm or eggs.

    Somatic gene therapy

  • 12

    transfer of a section of DNA to cells that produces sperm or eggs.

    Germline gene therapy

  • 13

    Categories of Gene Therapy:

    1. Somatic-Cell gene therapy 2. Germ Line gene therapy 3. Somatic cell enhancement 4. 4. Germ line enhancement.

  • 14

    for the cure and prevention of diseases.

    Somatic-Cell gene therapy

  • 15

    Example: insertion of a DNA sequence into a person's cell to allow production of an enzyme like adenosine deaminase.

    Somatic-Cell gene therapy

  • 16

    🙃🎀💌

    Example: Insertion of an adenosine deaminase sequence into early embryo or reproductive cells, which would affect not only the individual but all of his or her offspring.

  • 17

    Example: Insertion of a DNA sequence to improve memory, increase height, or increase intelligence which would affect only the individual.

    Somatic cell enhancement.

  • 18

    Example: Insertion of a DNA sequence for enhancement into a blastocyst, sperm or egg, which would affect future generation.

    Germ line enhancement

  • 19

    It is designed for diseases caused by loss of function of a gene, introducing extra copies of a normal gene may increase the amount of normal gene product to a level where the normal phenotype is restored.

    Gene augmentation therapy.

  • 20

    This is suitable for the treatment of infectious diseases, cancer and inherited diseases caused by the inappropriate gene activity.

    Gene inhibition therapy.

  • 21

    The aim is to introduce a gene whose product either: inhibits the expression of another gene or interferes with the activity of the product of another gene.

    Gene inhibition therapy.

  • 22

    Genes are directed to the target cells and then expressed so as to cause cell killing.Direct cell killing is possible if the inserted genes are expressed to produce a lethal toxin(suicide gene) or a gene encoding a prodrug is inserted, conferring susceptibility to killing by a subsequently administered drug.

    Gene therapy killing of specific cells.

  • 23

    At present, the type of therapy being undertaken is___

    somatic gene therapy
