How long is a piece of string.
When it's full of knots. Ar-ar-ar-ar-ar-ar-ar
Enzymes are smaller than the DNA they process in molecular size. This is because the DNA is a very long string of parts, whereas the enzyme is a single piece.
Charles William Beebe (American) naturalist, ornithologist, marine biologist, entomologist. Founder of Ecology
It takes one restriction enzyme to cut a linear piece of DNA (straight line) into two pieces. For a circular piece of DNA (plasmid), it would take two of these restriction enzymes - just think of how you would split a circle into two pieces; cutting one section will only straighten out the DNA, not split it (try cutting a rubber band for a visual).The answer to this question is completely dependent on the number of bands (representing different DNA fragment sizes) the lane produced. Since the first cut on a circular piece of DNA breaks the circle, then each consecutive cut will proceed as a linear band of DNA would.For example, if lane three produced four bands, then it took a total of three restriction enzymes (each enzyme reacting to one restriction site). Below is an example of the linear piece of DNA from lane three, with each "|" representing a restriction site. Notice how there are three restriction sites, but four fragments ("----") are produced.---- | ---- | ---- | ----As explained earlier, if a circular piece of DNA were cut to produce a linear piece like the one above, it would take one restriction site. From there, the enzymes proceed like the ones in the above example. Therefore, a circular piece of DNA that produced four bands would have used four restriction enzymes, whereas a linear piece of DNA that produced four bands would have used three restriction enzymes.

The Piece of String was created in 1883.
Maupassant published The Piece of String in 1883.
Jonathan Swift's "A Modest Proposal"
No - a piece of string can be any length you like.
100 metres seems to be the length of a spool of gardeners cotton Discuss:How_long_is_a_piece_of_string...we are not talking about jute twine here!So the maximum length of a piece of string would be 999.99mm!So the real answer to 'how long is a piece of string?' would be...anything between 0.01mm to 999.99mm.
He finds a small piece of string.
Only if it happens to be a 2 foot long piece of string.

You get another piece of string
You can attach any object - a small stone, for example - to a piece of string.
take a piece of paper and put it in a bottle and take a piece of string and light the string
