Answer
Operons are cluster of coordinated genes, including structural genes, an operator gene, and a regulatory gene.
Explanation:
In the The repressible operons, The transcription is usually on and repressor is in inactive form, So the specific genes are transcribed. While a regulatory molecule act as corepressor and binds to repressor protein to activate it. The repressor protein cause the inactivation of repressible operon (as the name indicate). E.g., Tryptophan Repress the trp operon.
A high level of product act as regulatory molecule (Corepressor) and turn off the operon, So anabolic pathways or synthesis of essential components are controlled by repressible operon.
In the Inducible operons, the transcription is usually off and repressor is in active form. So there is no transcription of genes. Specific Metabolite cause the activation of operon e.g lactose cause the induction of lac operon.
As a metabolite induces the operon, So they control the Metabolic pathways or breakdown of a neutrient.
The correct answer is D) Where water covers the land
Answer:I do know that it has dna and rna
Explanation:
Information coming from each eye goes to the opposite-side thalamus, where "inter neurons" receive and help process signals from sensory neurons and shuttle the data to the visual cortex.
Explanation:
Interneurons are the fundamental nodes of neural circuits, allowing message transfer among sensory or motor neurons and the central nervous system (CNS). They show dynamic characters in reflexes, neuronal oscillations, and neurogenesis in the grown-up mammalian brain. Interneurons (also recognized as association neurons) are neurons that are found exclusively in the central nervous system. That means that they are found in the brain and spinal cord and not in the peripheral segments of the nervous system.
There are 75% chances that their offsprings will be checkered.
Explanation:
The gene version allele is received by an individual and if they are different then the gene of the parent which is dominating is expressed in the offspring. However, in the case of co dominance the offspring gets the trait of both parent alleles.
So, in this case the mating of checkered rooster and checkered hen with co-dominance in their trait of genes will produce checkered offspring with a chance of 75 percent as can be calculated by the punnet square. The result will be 3 out of 4 checkered offspring.
