Answer:
b. False
Explanation:
Kozak consensus sequence acts as translation initiation site and is involved in the initiation of translation process.
The sequence is 5'-(gcc)gccRccAUGG-3' . AUG in the sequence is start codon and codes for methionine. It is highly conserved. R denotes a purine which means that it can be either adenine or guanine. Significance of bases inside brackets have not been properly confirmed.
Hence, the statement that Kozak consensus sequence defines the location of the transcriptional start site is false.
The best answer is C - plant, animal, atmosphere.
During daylight hours, plants capture carbon dioxide from the atmosphere and use it to make carbohydrates which is stored as starch in the plant. Animals feed on the plants and extract the carbohydrates through their digestive system. The carbohydrates, namely glucose, are used by the animals for production of ATP through cellular respiration.
Cellar respiration in the animals produces carbon dioxide as a waste product. The carbon dioxide is released into the atmosphere, from where it is again captured by plants and the cycle is repeated.
