A. SD sequences - d. Ribosome binding sites in prokaryotic mRNA
explanation - Shine darlago sequeence is a sequence which helps in the attachment mrna of the prokaryotic mrna with the ribosomes small subunit.
A. In a linear fragment of DNA, the ends can not be replicated by DNA polymerases. Eukaryotes use telomerase enzyme to replicate chromosome tips. This enzyme has - RNA polymerase activity
explanation - Eukaryotic dna ploymerase cannot replicate the end of dna so telomerase enzymes which is a rna polymerase thay used to extend certain base pair which helps in the replication of the end region.
