|
So it can hold massive amounts of DNA
|
|
|
Just in case it breaks, you have back up
|
|
|
DNA is actually a very short molecule
|
|
|
So it can’t be damaged by the sun

Detailed explanation-1: -It is found that longer DNA molecules exhibit significantly greater potency in gene expression; for example, the expression level for DNA with 25.7 kbp is 1000-times higher than that for DNA of 1.7 kbp.
Detailed explanation-2: -Answer c. The sequence of DNA bases is arranged into genes, most of which contain the instructions to build a protein. DNA stores information in the sequence of its bases.
Detailed explanation-3: -Although it is snaillike in retrieval speed compared with electronic and magnetic memory, DNA will be far better in terms of the scale of the data it can store and the time scale. “DNA is a remarkable media for long-term storage, ” said Karin Strauss, a Microsoft computer architect.
Detailed explanation-4: -During these thermal cycles, DNA primers bind to the target DNA sequence, enabling DNA polymerases to assemble copies of the target sequence in large quantities. PCR makes it possible to produce millions of copies of a DNA sequence in a test tube in just a few hours, even with a very small initial amount of DNA.
