Rna primer constructed during dna replication needs to be replaced because rna differs from dna. What does it contain?
inna [77]
Structurally speaking, RNA and DNA are different. One clear distinction between the two is that RNA is single stranded, while DNA is double stranded. Another way they differ is found in their nitrogen bases. The four bases for DNA are Adenine, Thymine, Cytosine, and Guanine (think, ATCG). The bases for RNA are the same, except Thymine is replaced with Uracil (think, AUCG).

Another note is that RNA polymerase is unable to detect errors in base pairings, unlike DNA polymerase, but their syntheses are both in the 5’3’ direction. Hopefully this helps you answer this question.

diamong [38]
<span>DNA replication is the production of identical DNA helices from a single double-stranded DNA molecule. Each molecule consists of a strand from the original molecule and a newly formed strand. Prior to replication, the DNA uncoils and strands separate. A replication fork is formed which serves as a template for replication. Primers bind to the DNA and DNA polymerases add new nucleotide sequences in the 5′ to 3′ direction. This addition is continuous in the leading strand and fragmented in the lagging strand. Once elongation of the DNA strands is complete, the strands are checked for errors, repairs are made and telomere sequences are added to the ends of the DNA.</span>
