Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many amino acids would be linked together to form a protein based on the DNA sequence-ATGGCTCGATCA?
A
1
B
2
C
3
D
4
Explanation: 

Detailed explanation-1: -There are about 20 amino acids and they link together in molecular chains called polypeptides, which are the building blocks of proteins.

Detailed explanation-2: -The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C).

Detailed explanation-3: -Combining four nucleotides in three-letter codes yielded 64 possible combinations (4 x 4 x 4), sufficient to describe 20 amino acids. They discovered the codes for other amino acids: for example, AAA for lysine and CCC for proline.

Detailed explanation-4: -8. The amino acid threonine is represented by the mRNA codon ACA.
