The DNA double helix is composed of two single-stranded DNA molecules. Which of the following statements is accurate when considering how the two single-stranded DNA molecules interact with each other (interstrand) and how the nucleotides interact within the same strand (intrastrand)? At both the interstrand and intrastrand level, nucleotides interact via covalent bonds. At the intrastrand level, nucleotides interact via phosphodiester bonds, while at the interstrand level, nucleotides interact via hydrogen bonds. At the intrastrand level, nucleotides interact via hydrogen bonds, while at the interstrand level, nucleotides interact via covalent bonds. At the intrastrand level, nucleotides interact via hydrogen bonds, while at the interstrand level, nucleotides interact via phosphodiester bonds. Antiparallel DNA strands interact only during replication.

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.
