Question

During replication of DNA, Okazaki fragments are formed in which direction?

• A. $3^{\prime }\to 5^{\prime }$
• B. $5^{\prime }\to 3^{\prime }$
• C. $5^{\prime }\to 5^{\prime }$
• D. $3^{\prime }\to 3^{\prime }$

Answer 1

Answer: (B)

$5^{\prime }\to 3^{\prime }$

Okazaki fragments are short, newly synthesised DNA fragments that are formed on the lagging template strand during DNA replication. They are complementary to the lagging template strand, together forming short, double-stranded DNA sections. DNA is synthesized from 5' to 3' direction.

So, the correct answer is option B.
