Protein Synthesis in Cells

Ribosomes are the cellular structures responsible for protein synthesis.
They serve as the site where messenger RNA (mRNA) is translated into polypeptides.

Bacterial Ribosomes

Bacterial ribosomes are composed of two subunits, known as the 30S and 50S subunits.
The larger subunit of bacterial ribosomes is the 50S subunit.

Nuclear Bodies

Nuclear bodies typically have irregular or spherical shapes.
They are membrane-less structures found within the nucleus.

Nuclear Membrane and DNA Arrangement

Nuclear bodies do not have a nuclear membrane surrounding them.
DNA molecules within nuclear bodies are arranged in a less structured, more fluid form, facilitating various regulatory processes.

Extrachromosomal Genetic Structures

Plasmids are extrachromosomal genetic structures that carry specific functions, such as antibiotic resistance.
They are circular DNA molecules that replicate independently of chromosomal DNA.

Composition and DNA Configuration of Plasmids

Plasmids contain double-stranded DNA that can vary in size and carry genes beneficial for survival.
The DNA in plasmids is usually circular, allowing for efficient replication and maintenance within the bacterial cell.
