Enzymes are sometimes called biological catalysts
DNA polymerase is an enzyme with a specific active site complementary to the 3' OH end of the DNA strand in terms of charge, size, orientation and shape thus can only bind to 3' end and cannot bind to 5' end for replication to occur
Answer and Explanation:
In homeostatic control processes any deviation from the norm sets into motion the appropriate corrective mechanisms which restore the norm. This rectification occurs through negative feedback. When you go outside wearing a sweater on a hot day, the body sends messages to the CNS and the following occurs:
- The superficial blood vessels vasodilate so that more blood flows near the surface. This encourages heat loss.
- Sweating and panting. Sweat secreted by the sweat glands evaporate from the surface of the body as it absorbs latent heat.
- The metabolic rate falls so that the body generates less heat. You also become less active
- Behavioural response by seeking cooler areas, cold drinks or removal of the sweater.
Answer:
<u>D) the nucleic acid (either DNA or RNA)</u>
<u />
Explanation:
Phages, or bacteriophages are viruses that infect bacteria.They have varying shapes, and sizes, and may contain one of two kinds of nucleic acid; these are RNA and DNA.
The nucleic acids are made up of nucleotides. These are genetic storage biomolecules made up of the monomers ribonucleic acid (RNA) deoxyribonucleic acid (DNA).
