According to molecular biology, a transcript
factor also known as sequence-specific binding factor is a protein that ASSIST
the rate of transcription of genetic information from DNA to messenger RNA by
binding to a specific DNA sequence. In order for it to be expressed at
the right cell at the right time its function is to regulate genes.
I’ll help but the image for me isn’t available sorry.
Answer:
The correct answer will be- Uncoupler (ionophore)
Explanation:
Valinomycin is a antibiotic which uncouples the process of ATP synthesis and the electron transport chain.
The valinomycin decreases the yield of ATP synthesis by allowing the inward movement of the K⁺ ions across the inner mitochondrial membrane. This inward movement disrupts the proton gradient which decreases the yield of the ATP synthesis.
Also, the consumption of oxygen increases in the electron transport chain which generates heat during ATP synthesis.
Thus, Uncoupler (ionophore) is the correct answer.
A hamster resulting from sexual reproduction would most likely have new
gene combinations.
Answer:
Chlorophyll molecules donate electrons to an electron acceptor in the reaction center.
Explanation:
Light reaction of photosynthesis takes place in the reaction centre. Light reaction may comprises of several proteins such as pheophytin, chlorophyll and quinones which act as light absorbing molecules.
The light reaction is the core of photosynthesis that produces ATP and NADPH to carry out the dark reaction for the production of high energy carbon molecules. During light reaction light photons are captured by photosystems such as photosystem I and II of chlorophyll in green plants. This photon cause the excitation of electron that flows through the electron transport chain from higher potential to lower potential and energy released by it is utilized for creating the gradient potential of H+ ions across the membrane. This gradient potential difference of H+ ions is used for the production of ATP through ATP synthase complex.
So chlorophyll molecules donate electrons to electron acceptors through the excitation of electrons from light photons in the reaction center.
