Answer:
Explanation:
Using Ohm's law
V ( voltage) = I (current A) × Resistance R in ohms
R = 7.0 × 10⁹Ω
V = 80 mV = 80 / 1000 = 0.08 V
0.08 V = I × 7.0 × 10⁹Ω
a) I = 0.08 V / 7.0 × 10⁹Ω = 1.142857 × 10 ⁻¹¹ A
b) quantity of charge = I × t = 1.142857 × 10 ⁻¹¹ A × 0.85 s = 9.7142857 × 10⁻¹² C
number of Na⁺ ions ( q = +e) = 9.7142857 × 10⁻¹² C / 1.6 × 10⁻¹⁹ C = 60714285.714 Na⁺ ions

Within a six-base DNA recognition sequence, an enzyme that cuts between the 3rd and 4th bases from the 5' end will generate blunt ends.
a)True
b)False
a) True
What is the function of restriction endonucleases in bacteria?
a) They serve no function.
b)They allow bacteria to genetically recombine with other bacteria.
c) They allow bacteria to engineer new DNA fragments.
d)They provide a defense mechanism against infection by viruses.
Our answer is surely D
d)They provide a defense mechanism against infection by viruses.
Explanation:
Restriction enzyme/restriction endonuclease:
Are produced by bacteria for cleaveing DNA at specific sites. Restriction enzymes cleave foreign DNA in the bacterial cell to fight against infecting organisms.
Pls Note:
Restriction enzyme are used by
bacteria to defend against bacterial viruses called bacteriophages or phages
Answer:
The statement is true
Explanation:
Asepsis means the absence of infection-causing germs and surgical asepsis means the absence of all the microorganisms or spores in any invasive process.
Surgical asepsis is usually used medical procedure when a foreign object is used to insert into the patient body which can open a transmission route of infection causing germs into the patient body. For example, using a catheter in patients.
So surgical asepsis is important to avoid any type of infection in the patient during his treatment. So the statement is true.
Answer:
The purpose of DNA replication is to produce two identical copies of a DNA molecule. This is essential for cell division during growth or repair of damaged tissues. DNA replication ensures that each new cell receives its own copy of the DNA.
