Answer:
Q = 813.12 j
Explanation:
Given data:
Mass of lead = 21 g
Initial temperature = 25°C
Final temperature = 327.5°C
Amount of heat absorbed by lead = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1
ΔT = 327.5°C - 25°C
ΔT = 302.5°C
Specific heat capacity of lead = 0.128 j/g.°C
Q = m.c. ΔT
Q = 21 g. 0.128 j/g.°C.302.5°C
Q = 813.12 j
DNA polymerase adds nucleotides at the 3' primer end of the DNA. This DNA polymerase checks the newly added base has correctly paired with the base in the template strand or not. Based on this it adds the new nucleotide.
<h3>What is nucleotide?</h3>
Nucleotide is the nucleoside with a phosphate group. It generally stack or link with each other to make a polynucleotide chain.
DNA polymerase adds these nucleotides one by one to the 3' primer end on the DNA strand.
It usually checks the correct pairing of the base with the template strand and then adds the new nucleotide to it.
Thus, by this step DNA polymerase choose nucleotides to put into the new strand.
