The term genetic engineering is used for :
RNA reaction technique
protein synthesis technique
Micro-organism which act as a vehicle for foreign gene transfer in higher plants
Assertion : "Rosie", the first transgenic cow, produced human protein-enriched milk.
Reason : The milk contained the human alpha for human babies than natural cow milk.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both the assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both the assertion and reason are false.
Which of the following pairs is correctly matched
Central dogma- Codon
Okazaki fragments - Splicing
RNA polymerase -RNA primer
Restriction enzymes - Genetic engineering
Cultivation of Bt cotton has been much in the news. The prefix Bt means
"Barium-treated" cotton seeds
"Bigger thread" variety of cotton with better tensile strength
produced by "biotechnology" using restriction enzymes and ligases
carrying an endotoxin gene from Bacillus thuringienesis.
Restriction enzymes are used in genetic engineering, because they
can degrade harmful proteins
can join different DNA fragments
can cut DNA at specific base sequence
are nucleases that cut DNA at variable sites
