Answer:
Normal Gene: AUC AUA GGA AAA UAC
Mutated Gene: AUC ACA GGA AAU UAC
Explanation:
The transcription takes place in the nucleus. This process involve copying of DNA sequence into mRNA (messenger RNA) sequence. mRNA too consists of 4 nucleotides except the fact that in mRNA the thymine (T) is replaced by uracil (U). This involves the following steps:
- Unwinding of DNA
- Binding of RNA polymerase to the unwinded DNA.
- Synthesis of RNA commonly mRNA
- RNA elongation
- Stop codon (UAA, UAG, UGA) initiating termination of synthesis of RNA
Potential energy=PE
PE=mgh
m=mass in kilograms.
g=9.8 m/s
h=height in meters
Data:
mass=500 Kg
h=110 m
PE=(500 Kg)(9.8 m/s²)(110 m)=539000 joules
