Tertiary structure is the overall three-dimensional structure resulting from folding and covalent cross-linking of a protein or polynucleotide molecule. This is what is explained in this question.
Answer:
They are also phenotypically plastics, or affected by a host of environmental influences as well as genetic ones.
Explanation:
Phenotypic plasticity refers to the possibility of having more than one phenotype when the organism is exposed to different environments. The genes and the environment work together for example if there is a person genetically predisposed to have a high IQ but who has socioeconomic conditions in which he has not been able to develop his cognitive abilities to the maximum then this will make his IQ not so high.
DNA is found in the nucleus of a cell. Depending on the type of cell, different parts of the DNA are used (example; if it's an eye cell, the DNA will use the segment that is dedicated to the functions of the eye). When a protein is needed, the DNA will split and in a process called transcription, the DNA messages are copied onto mRNA. The mRNA then leaves the nucleus through nuclear pores, and then travels through the cytoplasm to locate ribosomes which will produce the proteins needed to express whatever trait it codes for.
