MCQ on Genetic Code







Genetic code refers to the set of rules that govern the translation of genetic information carried by DNA or RNA into functional proteins. It involves the sequence of nucleotide triplets (codons), each specifying a particular amino acid or signaling the termination of protein synthesis. This is an MCQ on Genetic Code.

2. 
Which of the following nucleotide bases is NOT found in RNA and is replaced by another base?

3. 
The genetic code is degenerate, meaning that:

4. 
Which codon serves as the start codon, initiating translation in protein synthesis?

5. 
The genetic code is nearly universal, which means that it is:

6. 
Termination codons signal the end of the protein synthesis process. How many termination codons are there in the genetic code?

7. 
In the genetic code, which amino acid is coded by the start codon AUG?

8. 
Some codons are known as "wobble codons." What does this mean in the context of the genetic code?

9. 
The genetic code is read in a specific reading frame. How many nucleotides are read in each complete reading frame?
