Answer:
Fertilised ovum from sheep + cell in sheep's mammary gland isolation
Diploid one cell isolated + nucleus from ovum
Nucleus inserted into empty ovum
Ovum implanted in uterus of unrelated sheep
Ovum develops into foetus
Explanation:
In this process a nucleus from a fertilised ovum was removed and replaced with a diploid nucleus of a cell from the mammary glands of another sheep. The ovum was implanted into the sheep's uterus. The resulting foetus "Dolly" born similar to donor sheep.
Answer:
D) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
Explanation:
- Gene therapy is a technique for correcting defective genes genes by the insertion, alteration or removal of genes within an individual's cells and biological tissues to treat disease.
- Although gene therapy is considered as a potential method of treating several diseases but till now a little progress has been seen in this field.
- Several controversial points include, short lived nature of gene therapy, immune response , problems arising due to viral vectors and possible multigene disorder.
- There arefew ethical considerations that are to be kept in mind while using gene therapy like deciding what is disability and what is disorder, does searching for a cure demean the lives of individual, the preliminary attempts of gene therapy is very costly etc.
Because uv waves (ultra violet waves) are harmful to you, they could give you skin cancer or shorten your life
The technology can help scientists study or look at cells, which in turn can let those scientists figure out if a cell is infected with a virus, or if it's a mutated cell that might cause a disease.
Bias is a judgement that is not based on fact
Observation is usually the first step of an experiment
Scientists try to understand the phenomena that occur in the enviroment
These three are true
