The process by which the gene in the nucleotide suddenly changes its position is called.
1 answer:
Mutation is the process by which the gene in the nucleotide suddenly changes its position
Any change in the structure of a gen or in the usual DNA sequence of a cell is called mutation. It can be caused by mistakes during cell division when the DNA is copied or by the exposure to DNA damaging agents in the environment like UV light or cigarette smoke, and may be transmitted to subsequent generations.
A mutation is a permanent alteration of the nucleotide sequence of an organism, virus or other genetic elements.
There are three types of mutations:
- Base substitutions
- Deletions
- Insertions
The Deoxyribonucleic acid, also called DNA, is the hereditary material that carries genetic information for the development and functioning of humans and almost all other organisms. DNA is made of nucleotides.

Answer:
The time taken for the race is 17.20 s.
Explanation:
It is given in the problem that a 62.0 kg sprinter starts a race with an acceleration of 1.44 meter per second square.The initial speed of the sprinter is zero as it starts from the rest.
Calculate the final speed of the sprinter.
The expression for the equation of the motion is as follows;
Here, u is the initial speed, v is the final speed, a is the acceleration and s is the distance.
Put u= 0, s=30 m and .
Calculate time taken to cover 30 m distance.
The expression for the equation of motion is as follows;
Put u= 0, s=30 m and .
t=6.45 s
Calculate the time taken to complete his race.
T= t+t'
Here, t is the time taken to cover 30 m distance and t' is the time taken to cover 100 m distance.
Put s= 30 m, and s'= 100 m.
T= 17.20 s
Therefore, the time taken for the race is 17.20 s.
Answer:
c. joules
Explanation:
The rate at which a force displaces a mass a horizontal distance is measured in joules. In science, this phenomenon is known as work done.
Work done can be defined as the rate at which a force acting on an object or a body causes it to experience a displacement. The work done is a scalar quantity and is measured in joules (J).
Mathematically, work done is given by the formula;
Work done = force * distance
Where,
- W is the work done
- F represents the force acting on a body.
- d represents the distance covered by the body.
