Answer: option A - tumor-suppressor gene
Explanation:
A cancerous tissue is growing or spreading rapidly at a harmful rate. However, for a tissue to become cancerous, its "internal guard" usually known as a TUMOUR SUPPRESSOR GENE must have lost or reduced its function.
This loss of function occurs after mutation.
So, definitely, all affected individuals with cancerous tissues have mutated tumour suppressor genes unlike unaffected individuals.
Note that other options are WRONG, because none of them accurately distinguishes affected from unaffected individuals
The answer is C. anatomy because anatomy is the study of structure while physiology is the study of how the function works either mechanically or etc.
Answer:
The correct answer is 1 RNA Polymerase
Explanation:
RNA polymerase helps in the formation of RNA from DNA by the process known as transcription.There are 3 types of RNA Polymerase in Eukaryotic cell they are given below
1 RNA Polymerase 1 this enzyme helps in the synthesis of ribosomal RNA or rRNA.
2 RNA Polymerase 2 this enzyme helps in the formation of messenger RNA or mRNA .
3 RNA Polymerase 3 this enzyme helps in the synthesis of transfer RNA or tRNA.
<u>The eukaryotic cell differs from the prokaryotic cell in the following ways:</u>
- The eukaryotic cells have a <em>membrane-bound nucleus</em>, whereas the prokaryotic cell has a <em>non-membrane bound nucleoid</em>.
- According to the size, the eukaryotic cell is <em>large</em> when compared to the prokaryotic cell.
- The eukaryotic cell undergoes cell division through a process called <em>mitosis or meiosis</em>, whereas the prokaryotic cell divides through <em>fission or budding.</em>
- Membrane-bound <em>cell organelles</em> are present in eukaryotic cells whereas absent in a prokaryotic cell.
- The process of <em>gene expression</em> occurs in two different cell organelles (nucleus and cytoplasm) in the case of eukaryotic cells, whereas in the prokaryotic cell it occurs in the cytoplasm.
