Answer:

Option B, exposing the bacteria to an antibiotic that kills cells lacking the plasmid

Explanation:

Bacteria that have plasmid are selected from the ones that do not plasmid by placing them on antibiotics plates. As the bacteria that have plasmid within it will possess an antibiotic resistant gene due to which they are able to survive on the antibiotics plate and form colonies. While the bacteria that do not have plasmid die. These colonies of plasmid bacteria’s are grown to make large cultures from which plasmid protein is derived.

DIA [1.3K]

Answer:

Explanation:

Although protons resemble other positive ions such as Na+ and K+ in their movement across membranes, in some respects they are unique. Hydrogen atoms are by far the most abundant type of atom in living organisms; they are plentiful not only in all carbon-containing biological molecules, but also in the water molecules that surround them. The protons in water are highly mobile, flickering through the hydrogen-bonded network of water molecules by rapidly dissociating from one water molecule to associate with its neighbor, Protons are thought to move across a protein pump embedded in a lipid bilayer in a similar way: they transfer from one amino acid side chain to another, following a special channel through the protein.

Answer:

Template strand = complementary strand

GCA AG = CGT TC

TTA CG = AAT GC

GAT AC = CTA TG

CGG AT = GCC TA

DNA strand = mRNA strand

CGA TT = GCU AA

GCT TA = CGA AU

GCA TC = CGU AG

TTC AT = AAG UA

It is more important for DNA replication to be exact than transcription or translation because any error that occurs during DNA replication if not repaired will become permanent and will be transferred to the next generation.

Explanation: In DNA base pairing, G pairs with C and T pairs with A. But in RNA base pairing, G pairs with C and U pairs with A. DNA contains four bases G, C, T and A while RNA contains four bases G, C, A and U.
