#1
Which mammal was the first to be successfully cloned?
Sheep
ExplanationDolly the sheep was the first mammal to be successfully cloned in 1996.
#2
What is the term for the process by which a single cell develops into a multicellular organism?
Embryogenesis
ExplanationEmbryogenesis is the process by which a single cell develops into a complex, multicellular organism.
#3
Which organism was famously cloned by scientists in 1996, marking a significant breakthrough in reproductive cloning?
Dolly the sheep
ExplanationDolly the sheep was famously cloned in 1996, demonstrating the feasibility of reproductive cloning in mammals.
#4
What term describes the merging of an egg cell and a sperm cell during fertilization?
Syngamy
ExplanationSyngamy is the fusion of a sperm cell and an egg cell during fertilization, resulting in the formation of a zygote.
#5
What is the term for the process by which a fertilized egg attaches to the uterine wall and begins to grow?
Implantation
ExplanationImplantation is the process by which a fertilized egg attaches to the uterine wall and initiates the development of the embryo.
#6
What is the primary technique used in reproductive cloning?
Somatic cell nuclear transfer
ExplanationReproductive cloning primarily employs somatic cell nuclear transfer to create clones.
#7
In embryology, what is gastrulation?
Formation of germ layers
ExplanationGastrulation is the process during embryonic development where germ layers are formed.
#8
What is the term used to describe the development of an embryo outside the uterus, typically in a laboratory setting?
In vitro fertilization
ExplanationIn vitro fertilization refers to the process of fertilizing an egg outside the body in a laboratory.
#9
During which stage of embryonic development does organogenesis occur?
Neurulation
ExplanationOrganogenesis, the formation of organs, occurs during the stage of neurulation in embryonic development.
#10
What is the term for the process by which cells become specialized for particular functions?
Differentiation
ExplanationDifferentiation is the process through which unspecialized cells acquire specialized functions.
#11
What is the purpose of SCNT (Somatic Cell Nuclear Transfer) in reproductive cloning?
To generate an embryo using a donor nucleus
ExplanationSCNT is utilized in reproductive cloning to produce embryos from donor nuclei.
#12
What ethical concerns are associated with reproductive cloning?
All of the above
ExplanationEthical concerns related to reproductive cloning encompass various issues such as safety, societal implications, and the potential for misuse.
#13
Which of the following is a potential application of reproductive cloning?
All of the above
ExplanationReproductive cloning has various potential applications including medical research, conservation, and agriculture.
#14
Which ethical principle argues against reproductive cloning on the grounds that it could lead to the commodification of human life?
Dignity
ExplanationThe ethical principle of dignity argues against reproductive cloning due to concerns about the potential devaluation of human life.
#15
What is the main advantage of reproductive cloning in agriculture?
Ability to produce genetically superior livestock
ExplanationReproductive cloning in agriculture offers the advantage of producing livestock with desirable genetic traits for improved productivity and quality.
