Question

Which of the following are absent in the cytoplasm and genetic material of bacterial cells respectively?
A. Ribosome and pentose sugars
B. Golgi bodies and histone proteins
C. Mesosomes and amino acids
D. Chromatophores and DNA

Answer 1

Hint: The prokaryotes are the primitive organisms. The nuclear envelope is absent in such organisms. The DNA content is freely present in the cytoplasm. Bacteria are prokaryotic organisms. The cell organelles in the bacteria are not membrane bound.

Complete answer:
The bacterial cell is the prokaryotic cell in which the nucleus is not well defined. The cell organelles are not well defined in the bacteria. The DNA of the bacteria is usually called the chromosome. It contains the pentose sugar, phosphate group and nucleotide bases. It does not contain the histone proteins. Nucleosome structure is absent in the bacterial cells. It is present in eukaryotic cells. Ribosomes are the protein factories. They are freely present in the bacterial cell. Bacteria contain the folded invaginations in the plasma membrane called mesosomes. It is the bacterial organelle. Chromatophores are the color pigment or the group of light reflecting cells. It helps the animals for the dynamic camouflage and various kinds of communications. It is present in primitive animals and also in lower vertebrates.
The mitochondria and golgi complex are the membrane bound cell organelles. Prokaryotes do not contain the membrane bound organelles. Bacteria do not contain histone proteins also.
From the above information we have found that golgi bodies and histone proteins are absent in the bacteria.

Hence, the correct answer is option (B).

Note: Bacterial cells are found in many shapes and sizes. E-coli bacteria have many advantages in recombinant technology. The bacteria cell is enclosed in the rigid cell wall. It provides the shape of the bacteria. The functions for the cell growth, metabolism, and replication are carried out in the cytoplasm. Bacteria exist everywhere on the earth.
