The levels of protein structures are: PRIMARY, SECONDARY AND TERTIARY STRUCTURES.
The amino acid sequence and the bonding types between the amino acids determine the structures of proteins. Protein structures also determines the function of a protein, if a protein losses its structure it will not be able to perform its function again.
Functional groups play an important role in the formation of protein structure.Functional groups also participates in specific biochemical reactions in the body thus enabling the proteins to perform their functions.
Answer:
- Because soil has lost nutrients.
- To provide the right nutrients needed by a particular plant to grow.
Explanation:
Due to regulkar use of soil, the nutrients in the soil have been constantly used by the plants grown on it.
Due to this, soil has lost its value.
Application of fertilizer is one wey through which farmers artificially provide nutrients to the soil.
Therefore, application of fertilizers becomes neccessary for improved crop productivity.
Answer:
The role of a "leader sequence" is to B. determine whether transcription can proceed through the genes in the operon.
Explanation:
<em>The "leader sequence" is the 5′ untranslated region (5′ UTR). Its main function is the regulation of translation of a transcript using different mechanisms.</em> They differ depending we are talking about eukaryotes or prokaryotes (more complex). It determines whether transcription can proceed through the genes in the operon. The operon is is a functioning unit of DNA that is made of a cluster of genes under the control of a single promoter.
