Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During translation, the information written on mRNA is read and ____ ____ linked to form ____
A
ribosomal subunits, methionine
B
amino acids, protein chain.
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The mRNA is then pulled through the ribosome; as its codons encounter the ribosome’s active site, the mRNA nucleotide sequence is translated into an amino acid sequence using the tRNAs as adaptors to add each amino acid in the correct sequence to the end of the growing polypeptide chain.

Detailed explanation-2: -In translation, the codons of an mRNA are read in order (from the 5’ end to the 3’ end) by molecules called transfer RNAs, or tRNAs. Each tRNA has an anticodon, a set of three nucleotides that binds to a matching mRNA codon through base pairing.

Detailed explanation-3: -The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.

Detailed explanation-4: -Translation Translation takes place on ribosomes in the cell cytoplasm, where mRNA is read and translated into the string of amino acid chains that make up the synthesized protein.

Detailed explanation-5: -A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell. The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.
