Which organelle makes the proteins that are needed by the cell? a)cell membrane b)golgi apparatus c)ribosomes d)nucleus

The correct answer is -

c)ribosomes

Explanation:

Ribosomes can be described as large biomolecular complexes that are composed of RNA (particularly ribosomal RNA) and proteins.

They act as site for the synthesis of protien in both prokaryotes as well as eukaryotes.

mRNA (messenger RNA) arrives at ribosome after it gets transcribed from DNA.

mRNA gets converted to particular protein (through assembly of amino acids that are carried by specific tRNA molecules according to codons in the mRNA) that is needed by the cell.

This process is known as translation and it takes place at the site called ribosome.

Thus, option c) is the right answer.

I believe the correct answer is ribosomes.

The cell ribosome is a site where a procedure to make proteins called protein synthesis takes place. A ribosome is a complex structure of ribosomal RNA molecules and proteins.

To make the proteins, transcription of DNA to mRNA first occurs in the nucleus. A process called translation then occurs which is just reading the mRNA to understand the message it contains. mRNA is usually single stranded and has bases that code for specific amino acids that build up proteins. Making the mRNA from DNA is the first phase of DNA synthesis called transcription. A strand of mRNA is created and complements the strand of DNA. For Example, if the DNA coding was GAC ACT GAC, the complementary mRNA will be CUG UGA CUG. C complements for G, U complements for A and G complements for C. UAGCT are nitrogenous bases found in RNA and DNA. Transcription is divided into initiation where an enzyme called RNA polymerase binds to the promoter region signaling the DNA to unwind to enable the enzyme RNA polymerase to read of the 2 strands that make the DNA. Elongation is the second step where nucleotides are added the strand of mRNA with the complementary bases. Termination is the last step and the mRNA strand that complements the DNA is fully completes so it cuts away from the DNA. Translation of the mRNA then occurs so that a protein can be made. The mRNA leaves the nucleus and enters into the ribosome that reads the codons in the mRNA and molecules of tRNA carry amino acids into the ribosome according to how the codons of mRNA are arranged. In end, when the ribosomes translate to the terminating codon, the process of translation ends and a protein is made with amino acids arranged in the correct sequence.
