True/false, if false explain why
The SnRK2 protein kinase phosphorylates transcription regulators when Abscisic acid is absent, but in the presence of Abscisic acid, SnRK2 is inactive.
The answer is false.
Because the activity of Snrk2 gene depends on the presence of abscisic acid. Thses genes are activated during abiotic stress condition for plants. For example when there is low humidity or water content in the environment these snrk2 genes are activated in the presence of ABA and closes the stomata of the leaves and hence helps in preservation of water by checking evaporation from leaves.

1. You are interested in how cyclic-AMP-dependent protein kinase A (PKA) functions to affect learning and memory, and you decide to study its function in the brain. It is known that, in the cells you are studying, PKA works via a signal transduction pathway like the one depicted in Figure 16-15. Furthermore, it is also known that activated PKA phosphorylates the transcriptional regulator called Nerd that then activates transcription of the gene Brainy. Which, if any of the situations described...
True/false, if false explain why Microbial pathogens often synthesize growth regulators to manipulate the host plant.
You include an innhibitor of the protein kinase activity of TFIIH in an in virto transcription. What step in transcription would you expect to see blocked? Decribe an experiment you would run to test your hypothesis? Please explain the experiment part to the best of your ability.
True/false, if false explain why Jasmonic acid is a chemical, found in insect saliva, which is perceived by a plant receptor that initiates a response against the insect herbivore.
6. The gene for a hormone necessary for insect development contains binding sites for three transcription regulators called A, B, and C. Because the binding sites for A and B overlap, A and B cannot bind simultaneously. You make mutations in the binding sites for each of the proteins and measure hormone production in cells that contain equal amounts of the A, B, and C proteins. Figure 08-65 summarizes your results. For each of the following sentences, indicate if the...
the statement is true or false and then explain why. The portion of the human genome subjected to purifying selection corresponds to the protein-coding sequences.
True or False. If true, explain why. If False, gve a counterexample. If Σοη6" is convergent, Cnb is convergent, then Σ on(-2)" is convergent. True or False. If true, explain why. If False, give a counterexample. If Σ0n6n is convergent, then Σ cn(-6)n is convergent. True or False. If true, explain why. If False, gve a counterexample. If Σοη6" is convergent, Cnb is convergent, then Σ on(-2)" is convergent. True or False. If true, explain why. If False, give a...
A) True or False In bacteria it is possible for more than one protein to be translated from a single transcriptional unit? B) True or False Similar to prokaryotes a single rna polymerase holoenzyme is responsible for all transcription in an animal?
true or false and why? The isoelectronic point of a protein is influenced by the hydrophobic amino acids
True or False. Replace bold words to make statment true if false. When two protein chains combine to form an active protein, the structural level is quaternary. The dipeptide Gly-Lis is the same as the dipeptide Lis-Gly
