Regulation of Biochemical Pathways (5A)

Question 1

Sequencing of E. chlorotica DNA showed that certain genes essential for photosynthesis had been acquired by the slug from the nucleus of the algae. However, the majority of the mechanisms enabling E. chlorotica to harness ‘solar power’ remain unknown. Briefly contrast gene expression and gene regulation.

Answer 1

Gene expression is the process where information stored within genes is used to produce a functional product, typically a protein, via transcription and translation.On the other hand, gene regulation involves controlling gene expression to increase or decrease the production of specific products.

Question 2

Photosynthesis Terms

Answer 2

𝘌. 𝘤𝘩𝘭𝘰𝘳𝘰𝘵𝘪𝘤𝘢 would eat less than the black sea slug as they are able to undergo photosynthesis to produce their own food source, making them less dependent upon eating other organisms to produce energy.

Question 3

Student A wants to combine and average their results with Student B. Even though they plan to be honest and discuss this action in their report, Student B is still uncomfortable with the idea. Even after Student B expresses their concern, Student A combines their results anyway. Does this violate any bioethical concepts?

Answer 3

This action violates the bioethical concept of respect,as Student A has not acknowledged that Student B has the right and capacity to make their own decisions
