What scientist in 1952 discovered that DNA is actually two chains of molecules in spiral form?
Rosalind Franklin
Are sound waves are made up of chains and vibrating chains?
molecules
What very large organic compound made up of chains of smaller molecules?
A very large organic compound made up of chains of smaller molecules is a polymer.
Why does adding more initiators result in shorter polymer chains?
The more initiator molecules there are, the more chains get started. Since the chains compete for monomers, if there are 5 times as many chains obviously they will be shorter on average.
Is the most complex organic molecules are hydrocarbon chains with nothing else attached?
The simplest organic molecules are hydrocarbon chains. methane CH4, ethane H3C-CH3, Propane H3C-CH2-CH3, etc....
What scientist in 1952 discovered that DNA is actually two chains of molecules in spiral form?
Rosalind Franklin
What scientist proposed that DNA was a triple stranded helix?
Maurice Wilkins & Rosalind Franklin : they developed a high quality x-ray diffraction photographs of strands of DNA. these photographs suggested that the DNA molecule resembled a tightly coiled helix and and was composed of 2 or 3 chains of nucleotides .
What are some rosalind Franklin quotes?
Conclusion: Big helix in several chains, phosphates on outside, phosphate-phosphate inter-helical bonds disrupted by water. Phosphate links available to proteins. Rosalind Franklin The results suggest a helical structure (which must be very closely packed) containing probably 2, 3 or 4 coaxial nucleic acid chains per helical unit and having the phosphate groups near the outside. Rosalind Franklin We wish to discuss a structure for the salt of deoxyribose nucleic acid. (D.N.A.). This structure has novel features which are of considerable biologic interest. Rosalind Franklin While the biological properties of deoxypentose nucleic acid suggest a molecular structure containing great complexity, X-ray diffraction studies described here... show the basic molecular configuration has great simplicity. Rosalind Franklin You look at science (or at least talk of it) as some sort of demoralising invention of man, something apart from real life, and which must be cautiously guarded and kept separate from everyday existence. But science and everyday life cannot and should not be separated. Science, for me, gives a partial explanation for life. In so far as it goes, it is based on fact, experience and experiment.

What are molecules that are long chains of repeating molecules?
polymers
Are sound waves are made up of chains and vibrating chains?
molecules
What are molecules shaped like?
spiral chains
DNA molecules are shaped like what?
spiral chains
What is polypeptide chains?
Chains of amino acids are referred to as polypeptides. Proteins are created from one or more of these polypeptide molecules.
What very large organic compound made up of chains of smaller molecules?
A very large organic compound made up of chains of smaller molecules is a polymer.
What is organic compounds made of long chains of smaller molecules joined together to make large molecules?
polymers
Chains that contain only 2 glucose molecules are called?
Maltose.
Which of these statements is true of organic molecules?
They can be chains, rings, or branched structures.
