What is the importance of regulating gene expression

Biology
1 answer:
Sonja [21]3 years ago
3 0

Answer:

Regulated gene expression is crucial to the proper growth & survival of an organism and cannot be over-emphasized. Without it, the genetic code of a chromosome is the equivalent of a computer data file without the appropriate application to run it.

(03.05 hc) the base pairs in a dna strand are held together with hydrogen bonds. if the two nitrogenous bases in each pair were
asambeis [7]

The cell would have to take in and use more energy in order to break the covalent bonds.

The correct option is B

Hydrogen bonds :

are the chemical mechanism that governs the complementarity of the bases of DNA. This correspondence is unique thanks to the geometry of the hydrogen donor atoms and the acceptors that form the bases.

The (hydrophobic) bases are stacked inside the double helix of DNA; their plane is perpendicular to the axis of the double helix. The outside (phosphate and sugar) is hydrophilic.

The hydrogen bonds between the bases of one strand and the bases of the other strand keep the 2 strands united.

One purine on one strand necessarily binds to a pyrimidine on the other strand. As a corollary, the number of purine residues is equal to the number of pyrimidine residues.

* A binds to T (by 2 hydrogen bonds).

* G binds to C (via 3 hydrogen bonds: more stable bond: 5.5 kcal vs 3.5 kcal).

What part of the DNA strand do hydrogen bonds hold together?

hydrogen. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.

A cell under a microscope shows Two daughter cells were formed and they are haploid. Which stage of meiosis is the cell showing?
Nadya [2.5K]

The answer is <span>Meiosis I.</span>



<span>Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so each of these two haploid cells will in meiosis II produce two haploid cells. In total, meiosis results in four haploid cells.</span>

<span>
</span>

<span>Therefore, the production of two haploid daughter cells is in meiosis I.</span>

All the cells shown are part of the same organism. Which can you infer to be
Solnce55 [7]
The cell in the middle differs from its surrounding cells by having a double cell membrane hence the cells do not have the exact same structure and most likely do not come from the same cell. For cells to produce food molecules, I am not too sure but I feel that the question is referring to plant cells that are able to photosynthesize. Plant cells have a cell wall and a cell membrane hence is unlikely to be represented by most of the cells in this diagram. Thus by elimination, the answer could be having the same function
