Recycle and renew are the two R's that uses and transforms the waste material. Recyclables do not equate to renewable as recyclable materials do not occur naturally.
<h3>What are recyclable and renewable?</h3>
Recyclable is the resources that are used finite times over and over and undergo a certain process for re-use purposes.  They can be naturally or by humans, processed to be used again. 
Renewable is resources that are natural and are replenished in nature when gets decreased by natural processes. 
Some recyclables like aluminum and glass are not renewable as they are not formed naturally and do not get replenished by natural processes. 
Therefore, recyclables are not renewables.

Answer: The correct answer is B) Frameshift mutation.
The given  mRNA sequence is GGU-GCU-CCU-AUU. When a nucleotide is added at the fourth location in the chain, it entirely changes the frame from the insertion of the nucleotide till the end of the gene sequence. This is called a frameshift mutation.
This is because after adding a nucleotide, a new frame is generated that will code for different amino acids and therefore a different protein will be synthesized.
On the contrary, chromosomal mutation is an abnormality in the chromosome ( in terms of number or structure) whereas substitution mutation is the one, which exchanges one base with another. Deletion of base also results in the frame-shift mutation.
