4. Where is the ribosome located in the cell? What is the essential role of the ribosome
in gene expression?
5. In which crucial step of gene expression does the ribosome play a major role:
transcription or translation?
6. How does the ribosome differ in eukaryotes and prokaryotes?
7. Why is transfer RNA, or tRNA, necessary for protein synthesis?
8. What is the role of ribosomal RNA in the ribosome?
9. What happens if there are no ribosomes present in the cell, or if the ribosomes do
not function properly?

4. Ribosomes are tiny glanular structures that are either floating freely in cytoplasm or are bound to endoplasmic reticulum.

5. Translation.

6. Eukaryotic ribosomes are ten times larger than prokaryotic ones.

7. Not sure about this.But they are necessary for protein synthesis as they assemble amino acids into protein chains.

8. Ribosomal RNA is part of ribosome.These complex structures catalyze the assembly of amino acids into protein chains.They also bind tRNAs and various accessory molecules necessary for proteins.

9. When a ribosome is not working,it disassembles into two smaller units.

Explanation:

cats appear to have glowing cat eyes because the back of their eyeballs includes a special reflective surface called the tapetum lucidum. this lets them see better during the night, giving them a much better vision.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
