People who use complex tools like plows, irrigation, and fertilizers to grow domesticated plants are called farmers, it is a large scale activity and it´s use to obtain food from the earth, we also have horticulture, does not require hundreds or thousands of acres of land, horticulture is also important, but is more limited to the domestic and individual context, and finally it is much cheaper because it is not done at large scales like the Agriculture.

A nonsense mutation in a gene _____. A nonsense mutation in a gene _____. has no effect on the amino acid sequence of the encode
Delicious77 [7]

Answer:

introduces a premature stop codon into the mRNA

Explanation:

A nonsense mutation is a mutation in which an amino acid–specifying codon is changed into a termination codon or stop codon. A stop codon is a codon that does not code for any amino acid and serves to terminate the process of protein synthesis as ribosomes encounter it on the mRNA.

There are three stop codons: UAA, UAG, UGA. A nonsense mutation introduces a stop codon in place of an amino acid encoding codon. It results in the formation of truncated protein which is shorter than the normal protein. Truncated proteins are mostly nonfunctional.

All animals with eyes or the eyespots that have been studied so far share a gene in common. When the gene causes lack of eyes in
RSB [31]

Answer:

The correct answer is option C.

Explanation:

PAX5 refers to the member of the Pax gene family, which is, accountable for conducting the genetic information, which will encode the Pax-6 protein. It functions as a master control gene for the maturation of eyes and other sensory organs. Pax6 functions as a regulator in the formation of patterns and coordination needed for the proliferation and differentiation to take place effectively. This ensures that the procedures of oculogenesis and neurogenesis are taking place efficiently.  

The PAX6 gene was the outcome of evolution in earlier animals comprising eyespots or eyes. The similar PAX6 gene generates distinct kinds of eyes in distinct species because of the difference in its control of PAX6 expression. At the time of the evolution of vertebrates, the biological clock opsin’s rh gene was chosen as a gene for visual receptor pigments.
