Answer:

Option B

Explanation:

tRNA are single stranded just like most of the RNAs. Hence option A is incorrect. Due to the presence of specific L shaped structure, tRNAs bind specifically to only certain amino acids. Hence, option B is correct

There can be nearly 20 types of tRNAs based on the type of amino acids also their grouping can be done based on anticodon. Hence, on basis of amino acid, there can be 20 types of tRNAs. Hence, option C is correct

tRNAs carry anticodons that are made up of three nucleotides. Hence option D is also incorrect.  

Option B is correct

Explanation:

Eye is an organ because, the organs have blood vessels as well as the nerves in it, the organ is also present within the organ motif is also being executed in these organs. Similarly, inside the eyeball there is an organ which is known as retina, with is connected with the neural and epithelial tissue which helps in detection of the light which enters into the eyeball.
