Answer: below
Explanation: Genetic engineers are highly trained experts who use a variety of molecular tools and technologies to rearrange fragments of DNA. It’s the direct manipulation of an organism's genes using biotechnology.
Answer:
the answer for your question is 3 and 4
It is a very interesting question - the technology is real and the research on eDNA published in a journal in 2017.
eDNA stands for enviornmental DMA sampling. It allows scientist to test water samples for the presence of the DNA of the invasive fish species. It is more effective than traditional methods of sampling because it does not require trapping or sighting of the invasive species. Water samples can be collected anywhere any time and the DNA results are as accurate and detailed as collected from the invasive species themselves. It provides a complete picture of what invasive species are there.
Answer:
RNA polymerase enzyme is responsible for the formation of mRNA from DNA template during transcription.
