Question

If there was a problem with a protein being built incorrectly, but the DNA and RNA instructions were correct, what cell part do you think might be functioning incorrectly, and why?

A) Ribosomes; they may be malfunctioning during protein synthesis.
B) Nucleus; it may not be sending accurate genetic information.
C) Mitochondria; they may not be producing enough energy for protein synthesis.
D) Cell membrane; it may be blocking the correct protein molecules.

Answer 1

The ribosomes may be malfunctioning during protein synthesis, which could lead to incorrect protein assembly despite accurate DNA and RNA instructions.

Step-by-step explanation:

If a protein is being built incorrectly despite correct DNA and RNA instructions, the issue likely resides in the ribosomes, as they are responsible for protein synthesis through the process of translation. The DNA and RNA carry the correct instructions, but if the ribosomes malfunction, they may not be able to translate the RNA message into a proper protein structure. Ribosomes, made up of protein and rRNA, interpret the genetic information carried by mRNA, which includes the order of amino acids for the protein. If there is an issue at this stage, despite accurate information from the DNA and mRNA, the resulting protein may still be faulty.

Ribosomes are responsible for protein synthesis. They receive instructions from the DNA, which is transcribed into messenger RNA (mRNA). The mRNA then travels to the ribosomes in the cytoplasm, where the code in the mRNA is translated into a specific order of amino acids to build a protein.

If there is a problem with a protein being built incorrectly, but the DNA and RNA instructions are correct, the most likely malfunctioning cell part is the Ribosomes. Ribosomes play a crucial role in the process of protein synthesis. If they are not functioning properly, they may not correctly translate the mRNA code into the appropriate sequence of amino acids, leading to the production of faulty proteins.
