Concept explainers
a.
To determine:
The molecule that contains codon for protein synthesis.
Concept introduction:
Ribonucleic acid (RNA) is a
b.
To determine:
The molecule that contains anticodon.
Concept introduction:
Ribonucleic acid (RNA) is a polymeric molecule, which contain information for protein production in the form of nucleotide. It is present in cells and regulates various roles during protein production such as coding, decoding and finally gene expression.
c.
To determine:
The molecule found in the small subunit and the large subunit of ribosome.
Concept introduction:
Ribonucleic acid (RNA) is a polymeric molecule, which contain information for protein production in the form of nucleotide. It is present in cells and regulates various roles during protein production such as coding, decoding and finally gene expression.
