Question

Suppose you add fluorescent ribonucleotides to a cell undergoing dna replication so that the rna primers used in dna synthesis glow when viewed with a fluorescent microscope. you notice that, near each replication fork, one strand glows more than the other. which strand is it that glows more, and why? the lagging strand glows more because it forms the "trombone loop." the leading strand glows more because it forms the "trombone loop." the leading strand glows more because it is elongated nearest the replication fork. the lagging strand glows more because its rna primer is nearer the replication fork.

Answer 1

Answer: The lagging strand glows more because its RNA primer is nearer the replication fork.
During DNA replication process, both the strands of DNA are replicated simultaneously in opposite direction. One strand is replicated continuously and known as leading strand while the other strand is replicated discontinuously and known as lagging strand.  The leading strand has only one primer attached to it while the lagging strand
