Which of the Following Is Not Present in Prokaryotes

Their DNA fibrils are present in the center of the cell ie in the nucleoid. The DNA in prokaryotes is contained in a nucleoid which is not membrane-bound.

Prokaryote V Eukaryote Table Prokaryotic Cell Prokaryotes Nuclear Membrane

The answer is ribosome.

. Therefore ribosome is the right choice. Chloroplast Nucleus Ribosome Centriole. Such cells however do have ribosomes a cytoplasm and DNA as the genetic material.

This structure separates a cell from its surroundings. Protein making machinery is present in prokaryotes. The size of the cell is generally small.

The chromosomal heredity material is packaged in this organelle in eukaryotic cells but not in prokaryotic cells. Prokaryotic cells are characterized by the absence of a membrane-bound true nucleus and other membrane-bound organelles such as mitochondria Golgi apparatus ER. Asked Apr 23 2021 in Biology Microbiology by jen0811.

Endoplasmic reticulum Nucleus lysosomes vacuoles ribosomes centrioles 16 25 34 42 Cell - The unit of Life Botany Practice questions MCQs Past Year Questions PYQs NCERT Questions Question Bank Class 11 and Class 12 Questions NCERT Exemplar Questions and PDF.

They lack membrane-bounded organelles. Schlieden and Schwann stated the cell theory which in its modern form includes all of the following postulates except 1 point. The correct option is A.

Difference between Prokaryotic and Eukaryotic cells. A Naked DNA which is not bound to histones b An actively transcribed gene. A Repressor proteins b DNA-binding proteins c chromatin remodeling d Attenuation 12.

Endoplasmic reticulum Nucleus lysosomes vacuoles ribosomes centrioles 16 25 34 42. Cell division takes place by fission or budding. Which of the following methods of regulation is NOT present in prokaryotes.

This organelle is 1 point a. Prokaryotes lack membrane bound organelles so chloroplast and nucleus are absent. Cell division takes place by mitosis and meiosis.

They also lack membrane-bound organelles. The prokaryotic cell has the primitive nucleus with the disorganized genetic material. Presence of a Golgi body Presence of DNA Ability to maintain homeostasis Ability to produce ribosomes 1 See answer karlitanicole89 is waiting for your help.

How many of the following cell organelles are not present in prokaryotic cell. 4 - Chloroplast absent in plant cell. Attenuation - The Attenuation is not present in prokaryote because the repressors prevent transcription of a gene in response to an external stimulus whereas activators increase the transcription of a gene in response to an external stimulus.

Centrosomes are absent in prokaryotes because they divide by asexual method of reproduction like binary fission. Which of the following is NOT present in both prokaryotes and eukaryotes. Which of the following pieces of DNA would you expect to be most susceptible to DNase-I digestion.

Both repressors and activators regulate gene expression by binding to specific DNA sites adjacent to the genes they control. Nucleus present and well organized. Prokaryotes are single-celled organisms which all have cells in which there are no membrane-bound organelles.

In the given options Saccharomyces is not a prokaryote as it is a fungus and hence a eukaryote. The chromosomal hereditary material is packaged in this organelle in eukaryotic cells but not in prokaryotic cells. How many of the following cell organelles are not present in prokaryotic cell.

Which of the following is not present in a prokaryotic cell. Centriole is present only in animal cell. Membrane-bound cell organelles are absent in prokaryotic cells.

Simultaneous transcription and translation. Biology questions and answers. There are two main types of cells that living organisms have the prokaryotic cell or the eukaryotic cell.

They have a well-defined nucleus and membrane-bound nucleus. The correct answer is C. Mitochondria in eukaryotic cells contain ribosomes that are structurally similar to those found in prokaryotic cells.

Which of the following is not present in prokaryotes. A Ribosomes b Cell wall c Plasma membrane d Nuclear membrane. Their cell structure is more complicated than a prokaryotic cell.

A Nucleoid B None of these answers are correct с.
