Pea plants
These belong to legumes and legumes have a mutualistic relationship relationship with bacteria which allows them to add atmospheric nitrogen into the soil by a process called nitrogen fixation.<span />
        
                    
             
        
        
        
You could talk about how plants supply food for animals.
E.g cacti provide food and water for desert animals and rodents.
small rodents provide food for larger animals and snakes.
some animals will clean larger animals in a mutualistic relationship.
        
             
        
        
        
Answer:
RNA synthesis proceed in 5' to 3' direction.
Explanation:
The process of formation of RNA molecule from the DNA template is known as transcription. The transcription process is necessary for the gene expression.
The process of RNA synthesis always occur in the 5' to 3' direction. The RNA polymerase moves from the 3' strand and adds the polynucleotide and RNA synthesis in  5' to 3' direction. The anti parallel nature of the nucleotide causes the RNA synthesis in  5' to 3' direction.
 
        
             
        
        
        
Deletion- the fact that a codon is missing implies that the nucleotides were deleted.
