Answer:
The non-coding regions of DNA are called introns. They are significant in evolution since they offer a great 'recipe' for recombination with genes/exons. Therefore, this offers variations among individuals on which natural selection could act upon to help a population adapt to changes in the environment. Introns also offer an additional step in gene regulation through the splicing of introns in making of mRNA.
Answer:
A protist
Explanation:
In the given question, the characteristic of an unidentified organism are given which are:
1. The organism is unicellular and autotrophic which means that it is a producer and belongs to a plant like organism.
2. The membrane bound nucleus means that the organism is an eukaryote.
The organism is thus an unicellular, autotrophic and an eukaryote could be a species of algae which is considered a protist. The protists are the organisms which shows characteristic of the ukaryotes but are not considered true plants and animals.
Thus, a protist is correct answer.
Answer:
the earth
Explanation:
the rotation of the earth day,day and night
Answer:
The correct answer is - option B. Interphase is made up of the G1, S, and G2 phase and is the portion of the cell cycle where cellular contents are duplicated.
Explanation:
Interphase is the phase in the cell cycle in which the cell prepares to go under cell division by growing in size, replicating, or duplicate the cellular contents like DNA or genetic material and prepare for mitosis. Interphase includes the substages G1, S, and G2 phases.
It is known as the longest stage of the cell cycle as it includes four substages that takes time due to growing the cell, double the content and make the cell ready to go under division.
