The statement " Each gene in the human genome codes for a single protein. "is just wrong, as according to the basic knowledge of human genome, o<span>nly about 2 percent of the genome codes for proteins. This answer does make difference and clearly explaines why the previous one is wrong. Hope you will find it helpful!</span>
        
             
        
        
        
Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). ... Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins.  -google

Different structures and functions of roots
Explanation:
Roots are the underground descending non-green part of the plant.
Root functions: Anchorages the plant to the soil, absorbs water and nutrients from the soil.
Characteristics: Positively geotropic and hydrotropic, negatively phototropic; does not have nodes, internodes or stems.
Types:  
- Tap root
- Adventitious root – fibrous, foliar and true adventitious roots
Structure and functions:  
- Root cap or Calyptra: Cap-like structure covering the root tip
.
- Function: protects the meristematic tissues of the root, secretes mucilage which enhances the root tips to grow into the hard soil.
- Meristematic zone or growing point  sub-terminal behind root cap. These cells are inverted and looks like a dome. 
- Function – helps in the root growth by adding new cells to the root tip and other basal regions
- Zone of elongation behind the meristematic zone. 
- Function – helps in elongation of the root
- Root hair zone: This is the zone of differentiation where cells differentiate into vascular tissues like phloem, xylem, endodermis, cortex etc. 
- The main function of root hair is to increase the total surface area of root to facilitate more absorption of water and other nutrients from the soil
- Zone of maturation: the major and mature portion of a root. 
- Function  - lateral roots originates from this zone and radial differentiation leads to secondary growth.
