Answer:
Genetic engineers can transfer a specific piece of DNA or genes from one organism to another organism. This is usually done by adapting recombinant DNA methods. In this approach, a gene of interest is cut with restriction enzymes and then inserted and ligated to the host genetic material. This host could be a bacteria or eukaryote.
Example: Biotechnologists can produce insulin by inserting human gene in <em>E. coli</em>. The bacteria replicate its genome fast and produce protein (insulin) which can be extracted and applied to the person who is diabetic. Similar methods have been used for other purposes.
Answer:
Symbiotic soil microbes convert nitrogen gas to a form that the plants can use (NH4+ or NO3-)
Answer:
cancellation
Explanation:
A factor in the numerator is <em>cancelled by dividing it</em> by the same factor in the denominator. The quotient is 1, the multiplicative identity element.
The base pairing in a DNA molecule depends on the complementary nucleotides in the primary strand of the DNA. The base sequence in the complementary strand of the given DNA strand is GCCTGATCAATG.
<span>Central dogma by Crick is explaining how a gene is translated. It involves transcription and translation. Transcription is copying the message of DNA to mRNA. This message is translated in the cytoplasm by ribosomes with the help of tRNA to syntheise proteins which are basis of every metabolic reactions. This is an inference based on observations. For him it was found reasonable to infer the message should be carried from DNA to cytoplasm.</span>
