Rna primers must be present on which strand during dna synthesis?

Both on the leading strand and on each okazaki fragments of the lagging strand.

Explanation:

A primer is a short single-stranded RNA nucleotide that initiate DNA synthesis at the replication fork. Because DNA polymerase can not initiate replication on it own short strand of RNA primer synthesized by an enzyme RNA primase is needed to initiate DNA polynucleotide synthesis.

RNA primer is present on both leading and lagging strand.

RNA primer of about 10 nucleotides long are present on the leading strand and on each okazaki fragments on the lagging strand to initiate replication. The RNA primer is removed and replaced by DNA nucleotides by DNA polymerase.

it would be rhyolitic hope this

some scientists like gregory adcock agree with thorne's theory of regional continuity.

others, like chris stringer and ian tattersall, believe thorne's results may be contaminated or misinterpreted.
