sweet [91]3 years ago
4 0
Answer:


Active transport: movement against a gradient To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the proper concentrations of ions and molecules in living cells.

The diagram below shows some of the steps in protein synthesis.
Zinaida [17]

Answer:

According to the diagram shown, the section of DNA used to make the mRNA strand is known as a gene (option 2).

Explanation:

Gene consists of a DNA fragment that codes for the synthesis of a specific protein that defines the structural or functional trait of a living being.

When DNA is transcribed into mRNA, each section of transcribed DNA is part of a gene. The information travels to ribosomes in the cytoplasm where protein synthesis occurs.

A complete DNA molecule forms a chromosome, which contains the genes with information to define specific traits of a species.

The other options are not correct because:

<em>     1.Carbohydrate is a biomolecule that is not involved in the genetic process. </em>

<em>     3. Ribosome is where protein synthesis occurs. </em>

<em>     4. Chromosome is the complete DNA molecule.</em>
