Question

mRNA : transcription:: tRNA complete analogy​

Answer 1

Answer:

A cell is like a restaurant – differentiated cell types are like restaurants specialising in different cuisines

The DNA is the set of instructions for the cell – like a cook book is the set of instructions for a restaurant

A single DNA instruction is a gene – this is akin to a single recipe in a cook book

Transcription is the process of making an RNA copy of a gene – RNA polymerase is like a photocopy machine

The mRNA transcript (i.e. photocopied recipe) is transported to the ribosome – which functions as the cook

The ribosome reads the mRNA one codon at a time – as a cook would read the recipe one step at a time

Each codon corresponds to an amino acid – just like each step in a recipe refers to a specific ingredient

The amino acids are brought to the ribosome by tRNA – these tRNA molecules are like kitchen hands

The ribosome joins the amino acids together to make a polypeptide – just like a cook mixes ingredients to make food

Answer 2

The correct solution is translation.

• Transfer RNA, also known as amino acid acceptor RNA, adaptor RNA, or soluble RNA, is the RNA responsible for transporting activated amino acids from the cytoplasm's amino acid pool to the ribosome's protein synthesising site and thus aids in the translation process.
• It acts as a link between a certain amino acid and a specific mRNA codon as an intermediary, adapter, or connector molecule.
• They are the smallest nucleic acid molecules on the planet.
• 70-100 nucleotide residues make up a tRNA molecule.
• The folding of the main chain is a notable trait shared by all tRNAs.
• Each amino acid has its own set of tRNAs.
• Stop codons are not recognised by any of the tRNAs.
• The secondary structure of tRNA is similar to that of a cloverleaf, while the tertiary structure is similar to that of an inverted "L."
• The folded structure is created by hydrogen bonding between complementary bases.
