The primary benefit of folic acid is that it helps in preventing neural tube defects. Folic acid also known as Vitamin B9 are used as a supplementary vitamins taaken by many pregnant mother in order to develop the baby without deformities. Lacking of Folic acid causes neural tube defects define as an irregularities of the brain and spinal cord during the first week of prenancy

Determine whether each statement describes mitosis, meiosis, or both mitosis and meiosis.
svp [43]

Occurs in  organisms that  sexually reproduce ==> Occurs in meosis.

Meiosis is a type of gamete-specific nuclear division.

Meiosis occurs during spermatogenesis and oogenesis (egg formation in women).

In order for the number of chromosomes, characteristic of the species, to be conserved, it is necessary that before the encounter, the number of chromosomes of each of the reproductive cells be divided by two.

The reduction in the number of chromosomes takes place during the phenomenon called "meiosis".


Occurs during  growth and  development ==> It concerns mitosis.

Mitosis will ensure the good fulfillment of several phenomena:

. embryonic development,

. the general growth of organisms from birth to adult size,

. continued growth of certain organisms and / or organs; for example, trees, hair, teeth in ruminants, nails, ...


The DNA is  replicated ==> concern both mitosis and meiosis.

The cell cycle of eukaryotic cells is as follows:

• Interphase (normal functions, DNA replication)

G1 - growth / cellular activity

S - DNA synthesis / replication

G2 - preparation for division

• Phase M (cell division): which consists of either mitosis or meiosis, depending on cell types.

• Cytocinesis (cytoplasmic division).

So whether it is mitosis or meiosis, both are preceded by a replication of the genetic material (DNA)


Occurs in  all organisms ==> concern both mitosis and meiosis.

An organism is a set of elements that make up a functional structure.

In biology, the term organism designates a living being as it is organized, that is to say composed of different organs or organelles forming a coherent whole (as opposed to micro-organisms).

All multicellular organisms have sexual reproduction, so their cells are systematically mitosis and meiosis.

We exclude microorganisms of which a very small part of them have asexual reproduction.


The number of  chromosomes  remains the same : concerns only mitosis.

During mitosis, the human cell has 2n monochromatid chromosomes. In phase S consists of a doubling of the amount of DNA indeed, and the cells then have 2n chromosomes bichromatidiens. In the metaphase of mitosis, the chromosomes of the mother cell are arranged on a "metaphase plate", then split in 2-chromosomes, but monochromatids, during anaphase. Each daughter cell therefore has 2n monochromatid chromosomes.



The number of  chromosomes  reduces by half ==> Concerns only meiosis

Meiosis unfolds in two stages:

* The first meiotic division is called reductional because it allows to pass from 2n double chromosomes to n double chromosomes.

* The second is called equational because it preserves the number of chromosomes: one passes from n double chromosomes to n simple chromosomes.

Meiosis thus allows the formation of 4 haploid daughter cells (or gametes).

In humans, a normal cell contains 2n = 46 chromosomes (thus 23 pairs) while a gamete contains n = 23 chromosomes in two divisions).

What is true about the relationship of adenine and thymine?
MAXImum [283]
<span>DNA stands for deoxyribonucleic acid. The deoxy- in the DNA is a short term for deoxyribose. The nucleic acid molecule has three parts; sugar, phosphate and a base. The phosphate in the DNA acts as a backbone of the molecule. It is also responsible for the DNA’s ‘double-helix’ structure. The base has four codes namely adenine, thymine, cytosine and guanine. Adenine and thymine are bse pairs whereas cytosine and guanine are base pairs. They are not to be interchanged. Resulting in one cause mutation in the gene. </span>
