Okazaki fragments are: 1) short pieces of DNA resulting from restriction endonuclease digestion of DNA. 2) short pieces of newly-made DNA on the discontinuous strand. 3) short pieces of DNA resulting from the exonuclease activity of DNA polymerase I. 4) small pieces of DNA that become separated from a chromosome during mitosis. 5) Both (1) and (3) are correct.

5) Both (1) and (3) are correct.

Explanation:

Okazaki fragments are short sequences of DNA nucleotides (approximately 150 to 200 base pairs long in eukaryotes) which are synthesized discontinuously and later linked together by the enzyme DNA ligase to create the lagging strand during DNA replication.
