1. Which of the following is NOT true of Eukaryotes?

A. their nucleus contains the chromosomes

B. They contain membrane bound compartments

C. They contain ribosomes which are smaller than those of Prokaryotes

D. They contain many organelle in their cytoplasm

2. Which of the following Eukaryotic microbes generally do NOT contain a cell wall?

A. pungi, B. bacteria, C. algae, D. protozoa

3. In eukaryotes, this structure is studded with ribosomes. Proteins destined for the cell surface, or for outside of the cell, are produced here.

A. nucleosus, B. Smooth endoplasmic reticulum, C. rough endoplasmic reticulum, D. Golgi complex

4. In eukaryotes, this structure sorts proteins, modifies them, and repackages them.

A. Golgi complex, B. nucleous C.rough endoplasmic reticulum D. Smooth endoplasmic reticulum

5. Which of the following structures involved in motility (movement) do Eukaryotic process, but Prokaryotes do not?

A. pili , B. Flagella, C. Capsule, D. Cilia

Expert Solution

1. C

The ribosomes of eukaryotes are larger in size compared to prokaryotes.

2. B

The cell wall of fungi is made up of chitin, that of algae is made up of cellulose and protzoans is also made up of cellulose.

The cell wall of bacteria is made up of peptidoglycan and it is not a eukaryote. It is a prokaryote.

3. C

Rough endoplasmic reticulum double membrane bound organelle which is covered with numerous ribosomes. Ribosomes are active site for synthesis of proteins. Ribosomes are attached to endoplasmic reticulum responsible for the synthesis of proteins to be secreted outside the cell.

4. A

Golgi apparatus double membrane bound organelles found exclusively in eukaryotes. It is responsible for packaging and transportation of proteins within the cell and outside the cell.

5. D

Flagella is present in both prokaryotes and eukaryotes. Pili and capsule are present in only prokaryotes. Cilia is present only in eukaryotes.

Please rate high.

1. Which statement is true of the behavior of chromosomes in mitosis? All chromosomes are duplicated during interphase, except for the sex chromosomes If the original number of chromosomes was 46 each daughter cell will receive 23 Each new cell receives copies of all the original chromosomes The daughter cells will be unique due to crossing over 2.

1. Which of the following statements is TRUE regarding transcription in Eukaryotes? pre-mRNAs are most susceptible to degradation in the nucleus after addition of the poly(A) tail The template strand of DNA is utilized by RNA polymerase II to transcribe a gene The entire mRNA molecule produced during transcription is ultimately translated into protein dNTPs are utilized by RNA polymerase II during the elongation phase of transcription Mutations in the Kozak sequence will result in inability of RNA polymerase II...
