Answer the following questions about the accompanying diagram.

What name is given to the object looking like a string of beads that is closest to F?

Guida verificata passo dopo passo

Examine the diagram provided. The image illustrates the process of translation in genetics, where a strand of mRNA (labeled C) is being translated into a polypeptide chain.

Identify the labeled components in the diagram. The string of beads near F represents a growing polypeptide chain, which is being synthesized during translation.

Understand the role of the ribosome (labeled D and E). The ribosome facilitates the translation process by reading the mRNA sequence and assembling amino acids into a polypeptide chain.

Recognize that the string of beads closest to F is the polypeptide chain being synthesized. Each bead represents an amino acid, which is added sequentially to the chain as the ribosome moves along the mRNA.

Conclude that the object resembling a string of beads near F is called a polypeptide chain, which is the product of translation and will eventually fold into a functional protein.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Translation

Translation is the process by which ribosomes synthesize proteins using messenger RNA (mRNA) as a template. During translation, the ribosome reads the sequence of codons in the mRNA and assembles the corresponding amino acids into a polypeptide chain. This process is essential for gene expression and the production of proteins that perform various functions in the cell.

Translation initiation

Ribosome

The ribosome is a complex molecular machine found within all living cells that facilitates the translation of mRNA into proteins. It consists of ribosomal RNA (rRNA) and proteins, forming two subunits that come together during protein synthesis. The ribosome moves along the mRNA strand, decoding the genetic information and catalyzing the formation of peptide bonds between amino acids.

Ribosome Structure

Amino Acids

Amino acids are organic compounds that serve as the building blocks of proteins. There are 20 different amino acids that combine in various sequences to form proteins, each with unique properties that determine the protein's structure and function. In the context of translation, amino acids are brought to the ribosome by transfer RNA (tRNA) molecules, which match their anticodons to the codons on the mRNA.
