How might researchers modify a crop to yield a crop with preferred traits to help decrease nutritional problems around the world
babunello [35]

Answer:

Additionally, a series of GM crops have modified to express traits like an efficient use of soil nitrogen, which directly increases agricultural yield while reducing the use of fertilizers, and the new generation of diverse drought-tolerant, heat-tolerant and salinity-tolerant crops, which will increase the final yield

This model shows the basic process of making a protein. What are the strengths and limitations of this model?
Len [333]

Answer:

Results

We systematically analyze and compare how different modelling methodologies can be used to describe translation. We define various statistically equivalent codon-based simulation algorithms and analyze the importance of the update rule in determining the steady state, an aspect often neglected. Then a novel probabilistic Boolean network (PBN) model is proposed for modelling translation, which enjoys an exact numerical solution. This solution matches those of numerical simulation from other methods and acts as a complementary tool to analytical approximations and simulations. The advantages and limitations of various codon-based models are compared, and illustrated by examples with real biological complexities such as slow codons, premature termination and feedback regulation. Our studies reveal that while different models gives broadly similiar trends in many cases, important differences also arise and can be clearly seen, in the dependence of the translation rate on different parameters. Furthermore, the update rule affects the steady state solution.

Conclusions

The codon-based models are based on different levels of abstraction. Our analysis suggests that a multiple model approach to understanding translation allows one to ascertain which aspects of the conclusions are robust with respect to the choice of modelling methodology, and when (and why) important differences may arise. This approach also allows for an optimal use of analysis tools, which is especially important when additional complexities or regulatory mechanisms are included. This approach can provide a robust platform for dissecting translation, and results in an improved predictive framework for applications in systems and synthetic biology.

Definition: This is the system of exchange in the reservoirs of carbon in our environment.
Veronika [31]

Answer:

The carbon cycle

Explanation:

is the biogeochemical cycle by which carbon is exchanged between the biosphere, geosphere, hydrosphere and atmosphere of the Earth. The cycle is usually thought of as four major reservoirs of carbon interconnected by pathways of exchange.
