<span>At the top of plant shoots or roots of plants is an organism called meristem. This organism produces auxin, which causes the shoot or root to grow. This shows that by pinching off the tops of the plants, it makes them grow more.</span>
When babies are born, their brains contain about a hundred billion of neurons. However, a few of these brain cells are connected. At age three, there are one thousand trillion connections formed. The brain starts to cut off unused connections at the age of eleven.
Answer:
Option (1).
Explanation:
ATP (adenosine triphosphate) is the energy currency of the cell. The ATP molecule is hydrolyzes into ADP ( adenosine diphosphate ) and the inorganic phosphate.
Kinases are the enzymes that are known to add the phosphate group on the substrate. These kinases works in the energy dependent manner and require ATP for its reaction. The phosphate group can be transferred from one molecule to the other molecule as well.
Thus, the correct answer is option (1).
Answer:
DNA plasmid that contains both "old" and "new" gene segments and confers new characteristics to the organism in which it is placed.
Explanation:
During the genetic engineering procedure, which aims at producing an organism with better and desirable characteristics, a DNA called PLASMID is usually used to convey the gene of interest into the organism.
A plasmid is a self-replicating extra-chromosomal DNA found in the bacterial genome. The plasmid becomes a RECOMBINANT PLASMID when a foreign DNA of interest is inserted into it, in order to act as a vector (carrier). Therefore, a recombinant plasmid is a DNA plasmid that contains both "old" i.e bacterial genome and "new" i.e foreign gene segments and confers new characteristics to the organism in which it is placed.
