Answer:

No

Explanation:

During cyclic photophosphorylation, electrons are cycled continuously out of and back into the reaction center of PSI. It does not involve PSII and plastoquinone. During non cyclic photophosphorylation, the reaction center of plant photosystem II passes electrons to plastoquinone. The reduced plastoquinone carries electrons to the cytochrome b6f complex. Since PSII and plastoquinones are not included in cyclic photophosphorylation, dichlorophenyldimethylurea would not affect the process.

Describe the relationship between proteins and nucleic acid
Dmitry [639]

Answer:

Explanation:

Proteins and Nucleic Acids are not similar in structure. They look nothing alike, either as large molecules or in terms of their building blocks. While they're both made up of mostly carbon, hydrogen, nitrogen, and oxygen, the elements are assembled in vastly different ways. The major relationship between the two has to do with protein production -- DNA contains the information that a cell uses, with the help of RNA, to make protein.
