Answer:
Explanation:
The double-stranded DNA molecule has the potential to store genetic information in either strand, although in most organisms <u>only one strand is used to encode any particular gene</u>.
The template strand is the non-coding strand. The coding strand of DNA is the non-template (mRNA-like) strand (see attachment).
Thus, genetic information is expressed by transcription of the non-coding (template) strand of DNA, <u>which produces an mRNA molecule that has the same sequence as the coding strand of DNA</u>. Therefore, if a mRNA is transcribed from the non-template strand, the genetic information will not be contained in that strand and it would not produce a correct protein.
The answer would be truly led
Answer:
Cell membrane
Explanation:
In the cell membrane, there is the process of transport of substances, with energy expenditure, through the mediation by specific carrier proteins.
This usually occurs from the lowest to the highest concentration medium in the cell (against the concentration gradient). This process is called active transport.
Some examples of substances that can be actively transported across the membrane are: Iron, potassium, iron, hydrogen, calcium and sodium ions (as described in the question), as well as some types of amino acids and sugars.
