Answers

Answer 1
Answer:

A change in the natural sequence of bases in DNA structure is called a mutation.

  • The mutations are responsible for altering the nucleotide sequence of the DNA and can be caused due to several reasons which can be physical, chemical or intrinsic factors.
  • The effect of these mutations on the organisms can be positive (beneficial), negative (harmful) or neutral (no effect).
  • The mutations can be broadly classified into 2 categories based on the change produced in the nucleotide sequence :

1. Pointmutation - This mutation result in the change of single nucleotide in the given DNA sequence. For e.g in a sequence AGGAATC if G changes to C the new sequence would be ACGAATC and this is called a point mutation.

2. Frameshiftmutation-This mutation refers to the alteration of the open reading frame of a sequence due to insertion or deletion of several nucleotides in a sequence for e.g if you have a sequence AAATTGG and there is a deletion of AATT  you get AGG. This is an example of a frameshift mutation.
Answer 2
Answer: The term that you are looking for is a mutation a change in the base code of DNA (deoxyribonucleic acid)

The processes of transformation and transduction are important to which kingdom and why?

Answers

Bacteria: Both processes provide the Bacteria with new genes that might provide new ways of dealing with environmental changes.

Final answer:

Transformation and transduction are crucial processes in the Kingdom Bacteria and to some extent in the Kingdom Archaea. They both contribute to genetic variation in bacterial populations, aiding in their adaptability.

Explanation:

The processes of transformation and transduction are vital in the Kingdom Bacteria (and also play roles in the Kingdom Archaea). Transformation involves a bacterium taking in DNA from its environment, allowing the bacterium to acquire new traits—this can potentially include pathogenic traits.

Transduction, meanwhile, is a process whereby a virus (a bacteriophage) transfers DNA from one bacterium to another, leading to genetic recombination. Both processes aid in increasing genetic variability in bacterial populations, which can help these organisms adapt to changing environmental conditions.

Read this sentence by Ralph Ellison:When I discover who I am, I'll be free.

The author uses the word discover to emphasize which idea about freedom?

A.
It requires a journey of self-knowledge.
B.
It's made possible through education.
C.
It means following a set path.
D.
It's an impossible task for everyone.

Answers

Final answer:

The author uses the word 'discover' to emphasize that freedom requires a journey of self-knowledge. Correct option is A.

Explanation:

The author uses the word discover to emphasize that freedom requires a journey of self-knowledge. By using the word 'discover,' Ralph Ellison suggests that freedom is not something that is given or granted, but rather something that one must actively seek and uncover within themselves. This idea aligns with the theme of self-realization and individual agency, as the process of discovering who one is is a personal and transformative experience.

Exposing inner mitochondrial membranes to ultrasonic vibrations will disrupt the membranes. However, the fragments will reseal "inside out." These little vesicles that result can still transfer electrons from NADH to oxygen and synthesize ATP. If the membranes are agitated further, however, the ability to synthesize ATP is lost. After the further agitation of the membrane vesicles, what must be lost from the membrane? A) the ability of NADH to transfer electrons to the first acceptor in the electron transport chain B) the prosthetic groups like heme from the transport system C) cytochromes D) ATP synthase, in whole or in part E) the contact required between inner and outer membrane surfaces
