Answer:
The 5' end has free phosphate group while the 3' end has free OH group.
Explanation:
Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.
E transformation in creating bacteria genetically engineered to produce human proteins.
Small, single-celled organisms called bacteria exist. Nearly all areas of the world are home to bacteria, which are essential to their ecosystems. Some species can survive in environments with high pressure and temperatures. The average person's body is teeming with bacteria, and it's thought that bacterial cells outnumber human cells. The bacteria that hurt us are the bad ones.
They are known as pathogens. These might be picked up from our surroundings. Vibrio cholera, the bacteria that causes cholera, can be obtained through consuming food or water that has been tainted with an infected person's feces, as well as by coming into direct touch with an infected person.
