Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A linear code of three sequential bases on one side of a DNA molecule is a ____
A
codon
B
gene
C
amino acid
D
base pair
Explanation: 

Detailed explanation-1: -DNA is “read” by using three-base sequences to form “words” that direct the production of specific amino acids. These three-base sequences, known as triplets, or codons, are arranged in a linear sequence along the DNA. A linear stretch of DNA that codes for a specific protein is called a gene.

Detailed explanation-2: -The mRNA bases are grouped into sets of three, called codons. Each codon has a complementary set of bases, called an anticodon.

Detailed explanation-3: -Hidden within the genetic code lies the “triplet code, ” a series of three nucleotides that determine a single amino acid.

Detailed explanation-4: -A sequence of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid. Certain codons signal the start or end of translation. These are called start or stop (or termination) codons.

Detailed explanation-5: -Each genetic code consists of three ribonucleotide letters, thus referred to as a triplet code. As such, a genetic code is a triplet code in which a sequence of three bases is needed to specify one amino acid.
