I am not sure that there is a species on Earth where the CELLS are helical in shape and joined together in chains.

The two long chains in DNA are called nucleotide strands. These strands are made up of smaller units called nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base. The nucleotide strands are complementary and form a double helix structure.
double helix ramon c.
Amino acids bond together to make long chains and those long chains of amino acids are also called proteins.

A DNA strand is shaped like a 'double helix'.
DNA is shaped like a double helix. It is stored in cells in the form of chromosomes, which are long strands of DNA wrapped around proteins called histones. These chromosomes are organized in the cell's nucleus.
First of all, RNA is a single helix. It isn't really similar to the DNA in the obvious shape. In DNA there two long polynucleotides chins which are right handed double helix. the chains are antiparallel to each other. while in RNA there is only a single chain.
i want the answer u are stupid
Normally, DNA forms a right-handed double helix but it can also come in other forms.
Deoxyribonucleic acid, desoxyribonucleic acid, DNA ((biochemistry) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix; associated with the transmission of genetic information. (WordNet)
