Anaerobic respiration uses electron receptors other than oxygen molecules. Anaerobic respiration produces a maximum of 2 ATP (Adenosine triphosphate) per glucose!
Taxol is a drug that comes from the bark of a tree that binds and irreversibly stabilizes microtubules. It is often used during chemotherapy to kill dividing cancer cells. How does taxol block cell division?
A-
Taxol prevents the contractile ring from forming and dividing the cell in two.
B-
Taxol prevents DNA replication.
C-
Taxol prevents chromosome condensation during prophase.
D-
Taxol prevents spindle formation and separation of chromatids.
Answer: D-
Taxol prevents spindle formation and separation of chromatids.
Explanation:
The Taxol is used as an anticancer drug formulation. It is obtained from yew tree. An anticancer drug affects the cell cycle machinery so as to limit the production of cancer cells. This drug ceases the microtube formation in animal cells. This prevents the spindle fiber formation and further prevents the mitosis of cancerous cancers as the chromosomes will not separate apart and so abnormal cells will not produce further.
Answer:
In bacteria, the Shine-Dalgarno (SD) sequence is a ribosomal binding motif that is localized upstream the initiation codon and helps to bind the ribosomal subunit. Moreover, the formylmethionine (fMet) on tRNA is found in bacteria and also in eukaryotic organelles
In eukaryotes, the Kozak sequence (A/GCCACCAUGG) is a sequence that helps to start the translation process
