Answer: A single strand
Explaination:RNA and DNA are macromolecules made up of nucleotides organised in chains. DNA has double strands organised in a helical shape.
Answer:
The correct answer is option c. "formation of protocells that use DNA to direct the polymerization of amino acids".
Explanation:
The polymerization of amino acids is a complex biological function that involves multiple proteins and cofactors working together at different locations in the cell. Even though there are some scientific advances in the production of synthetic protocells (cell like structures made from synthetic particles), the formation of protocells able to synthesize amino acids from DNA directly has not been accomplished.
Answer:
The Lipid Bilayer
Explanation:
The lipid bilayer has been firmly established as the universal basis for cell-membrane structure. It is easily seen by electron microscopy, although specialized techniques, such as x-ray diffraction and freeze-fracture electron microscopy, are needed to reveal the details of its organization. The bilayer structure is attributable to the special properties of the lipid molecules, which cause them to assemble spontaneously into bilayers even under simple artificial conditions.
