A mutation is any change in the sequence of DNA because of any reason such as deletion, insertion, etc. To determine the mutation in a DNA molecule changed the structure of a specific protein scientists should know the normal sequence of bases that code for the protein.
What is mutation?A mutation is a random change in the DNA sequence either due to insertion, deletion, or substitution.
By mutating a gene's code for making a protein, a variant can leads to a protein's improper functioning or to not being produced at all.
Scientists must mandatorily determine the normal base sequence of the protein code before investigating the mutation in the DNA sequence for a particular protein.
Thus, the correct option is A.

Is interphase before or after mitosis?
Answer: The interphase is the longest part of the cell cycle. This is when the cell grows and replicates its DNA before entering mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix refers to each other, so the interphase occurs between one mitotic (M) phase and the next mitotic (M) phase.

Jolie is on the weightlifting team at her school. She must lift as much weight as possible from the ground to a straight up standing position. How much work will Jolie do if she uses a force of 5 N to lift 150 pounds of weight to a height of 1.5 m?
Answer:
7.5N
Explanation:
work=Force* distance
= 5*1.5
= 7.5N
Jolie is on the weightlifting team at her school, She uses a force of 5 N to lift 150 pounds of weight to a height of 1.5 m, so the work she will do is 5057.55 joules to lift the weight.
What effect does weightlifting have on the body?It is one of the types of exercises that increase muscle strength because lifting weights places stress on the muscles, allowing the muscles to adapt to the weight and increase muscle strength while improving mental health. It improves the heart's health, improves the blood circulation, and keeps the body fit, but excessive weight lifting is unhealthy and dangerous for the body.
Hence, Jolie is on the weightlifting team at her school, She uses a force of 5 N to lift 150 pounds of weight to a height of 1.5 m, so the work she will do is 5057.55 joules to lift the weight.
