DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Proteins are created when
A
When a string of amino acids fold into a specific, complex 3-dimensional structure
B
A string of amino acids bond with a nucleotide
C
tRNA matches an amino acid to it’s codon
D
When monosaccharides bond to make polysaccharides.
Explanation: 

Detailed explanation-1: -Proteins are built as chains of amino acids, which then fold into unique three-dimensional shapes. Bonding within protein molecules helps stabilize their structure, and the final folded forms of proteins are well-adapted for their functions.

Detailed explanation-2: -The amino acid sequence of a protein determines its three-dimensional shape. The structure of a protein can be described in several levels.

Detailed explanation-3: -Proteins are made up of lots of little building blocks called amino acids. The exact 3-D shape of the protein depends which amino acids it’s made of and how they’re put together. When a protein bends and twists to form its 3-D shape, this is called protein folding.

Detailed explanation-4: -Protein tertiary structure is the three dimensional shape of a protein. The tertiary structure will have a single polypeptide chain “backbone” with one or more protein secondary structures, the protein domains. Amino acid side chains may interact and bond in a number of ways.

Detailed explanation-5: -The overall three-dimensional structure of a polypeptide is called its tertiary structure. The tertiary structure is primarily due to interactions between the R groups of the amino acids that make up the protein.
