Is DNA branched or unbranched?

Branched DNA There is, however, a catch; the axes of DNA double helices are unbranched lines. Joining DNA molecules by sticky ends can yield longer lines, perhaps with specific components in a particular linear or cyclic order in one dimension.

Are nucleic acids unbranched?

Depending on their sequences and environmental conditions, DNA and RNA may adopt a variety of secondary structures such as double-stranded helices, bulges, hairpins, and three-way and four-way branches, which have been described in various reviews.

Are nucleic acids linear or branched?

Nucleic acids are linear polymers (chains) of nucleotides.

Is DNA an unbranched polymer?

Both DNA and RNA are linear, unbranched polymers of subunits termed nucleotides.

Can RNA form branched structures?

Branched RNAs with two and four strands were synthesized. These structures were used to obtain branched siRNA. The branched siRNA duplexes had similar inhibitory capacity as those of unmodified siRNA duplexes, as deduced from gene silencing experiments of the TNF-α protein.

What are nucleic acids describe the structure of DNA?

Nucleic acids are long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.

What are nucleic acid describe the structure of DNA?

Basic structure Nucleic acids are polynucleotides—that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.

Which statement correctly identifies a feature of a double stranded DNA?

Which statement correctly identifies a feature of double-stranded DNA? Each strand has a 3′ end (unbound hydroxyl group) and a 5′ end (hydroxyl group of deoxyribose sugar); the two strands run antiparallel to each other. You just studied 13 terms!

What is amino acids polymer?

Polymers of amino acids are proteins. This means that proteins are made up of repeating units of amino acids. Proteins are also known as polypeptides.
