Answer:
The list number is between 4 and 24
Explanation:
Answer:
chemotaxis
Explanation:
Chemotaxis is movement of the organism in the response to the chemical stimulus.
Bacteria, somatic cells and single-cell as well as multicellular organisms direct movements of their body according to some chemicals in the environment. This is very important for the bacteria to find the food by swimming toward highest concentration of the food molecules or also to flee from the poisons.
<u>Thus, it is a process by which various cells are drawn to the target area by a microbe invader.</u>
Answer:
<em>Cellular transport is the movement of ions or molecules across the membrane of the cell through either active or passive process.</em>
Explanation:
During active transport, ATP (Adenosine triphosphate) is used. In passive transport, ATP is not used. In active cellular transport, the ions move across the membrane against the concentration gradient.
For ATP to be used, it has to get hydrolyzed thereby forming ADP and inorganic phosphate. On the other hand, ADP captures the energy through the oxidation process taking place in the cell.
Answer:
The correct answer is A When dTTP is bound to the specificity site, more dCDP is produced
Explanation:
Ribonucleotide reductase catalyzes the conversion of ribonucleotide to deoxyribonucleotide.
When dTTP is bound to the specificity site at that time dCDP is produced.The So formed dCDP is converted to dUDP by the help of dCDP deaminase.The dUDP is then converted to dUTP by phosphorylation.
Finally the dUTP is converted to dTTP by the catalytic activity of thymidylate synthase with the presence of N5 N10 methylene tetrahydrofolate.
Thus equal amount of deoxyribonucleoside triphosphates are maitained by the cell.
