Final answer:
A fragment that is 2.3 kb is 2300 base pairs.
Step-by-step explanation:
The size of a DNA fragment, measured in base pairs (bp), can be calculated using the formula
Size of fragment (bp) = Length of fragment (kbp) * 1000
In this case, the fragment is 2.3 kb (kilo base pairs), so:
Size of fragment (bp) = 2.3 * 1000 = 2300 bp
Therefore, the fragment that is 2.3 kb is 2300 base pairs.
