Answer:
2) CAG - TTC - ACG mutates to CAG - TTC - ACC - ACG
Explanation:
Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. The number of base pairs inserted can range from one to thousands!
In option no. 1: We see that there is not addition of a single or more than one base, but the new base sequence is different from the original sequence at three places i.e: TTA - CAC - G
In option no. 2: The insertion of three bases ACC has been made exactly after TTC, the whole sequence and arrangement of bases remain same except this insertion.
In option no. 3: The first base of the sequence T is replaced with A, and all other sequence is same. This type of mutation is called substitution in which one base is replaced by other.
In option no. 4: The last base of the sequence C is deleted, and is not present in new sequence. This type of mutation is called deletion in which a base is removed from the sequence.
Conclusion: Therefore, the best option is 2, in which whole codon is inserted in the DNA base sequence.
The correct answer for the question that is being presented above is this one: "Each piece contains the same number of atoms." The <span>statement that correctly describes these broken pieces of the sample is that each piece contains the same number of atoms.</span>
Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.
Viruses enter a host cell when the host cell recognizes and binds the glycoproteins on the virus's surface, then take in the virus by phagocytosis. Thus, d. is the correct answer.
Answer: The body systems that are involved are:
--> Nervous System and
--> muscular system.
Explanation:
The body is made up of different organ systems which usually works together to bring about proper functioning of the living organism. Examples of the body systems includes:
--> The nervous system: This system enables the animal to detect and respond to stimuli rapidly.
--> The muscular system: This system enables the organism to move from one location to another.
Both the nervous system and the muscular system work together to bring about coordination of activities. When you step on a tack and jeck away, sensory receptors detects stimuli from the external environment and pass the information received as an electrical impulses to the brain through the nerve fibres. The information is processed in the central processing region which is the brain.
The effectors such as the muscles goes into action upon receiving nerve impulses from the brain. Such actions includes muscular contractions which helps you to pick up the tack and put it on your desk.
