B) small sections of nonsense code found between genes.
C) protein fragments released from a proteasome.
D) sections of newly formed DNA, built on the leading (3' to 5') template strand.
E) small sections of DNA that do not code for protein found within a gene.

Question

Quizplus · Accepted Answer

Okazaki fragments are short sequences of DNA nucleotides which are synthesized discontinuously and later linked together by the enzyme DNA ligase to create the lagging strand during DNA replication. They are formed on the lagging strand because DNA polymerase can only synthesize DNA in the 5' to 3' direction, necessitating a piecewise approach to replicate the 3' to 5' template strand.
