DNA replication is semiconservative in the sense that is uses one old strand to create a new strand.
Thus, it conserves a strand to create a new item in a sense.
Hope this helps!
A plant that is only alive for two years is called a biennial. <span />
The sequential pathway of a protein from it first starts to be translated to its release from the cell is cytosol > ER > Golgi > vesicle > plasma membrane > external environment. These proteins are synthesized in the ribosomes.
The exported proteins are synthesized (i.e., translated) in the ribosomes of the cytosol that bound to the endoplasmic reticulum in order to enter into the endomembrane system.
Subsequently, extracellular proteins undergo processing in the Golgi apparatus, which is connected to the rough RE by transport vesicles.
Finally, these proteins pass through transport vesicles in order to be exported from the cell by endocytosis.

Pairs of Unit Factors, or Genes
Mendel proposed that paired unit factors of heredity were transmitted faithfully from generation to generation by the dissociation and reassociation of paired factors during gametogenesis and fertilization, respectively. After he crossed peas with contrasting traits and found that the recessive trait resurfaced in the F2 generation, Mendel deduced that hereditary factors must be inherited as discrete units. This finding contradicted the belief at that time that parental traits were blended in the offspring.
A gene is made up of short sections of DNA that are contained on a chromosome within the nucleus of a cell. Genes control the development and function of all organs and all working systems in the body. A gene has a certain influence on how the cell works; the same gene in many different cells determines a certain physical or biochemical feature of the whole body (e.g., eye color or reproductive functions). All human cells hold approximately 21,000 different genes.
Genetics is the science of the way traits are passed from parent to offspring. For all forms of life, continuity of the species depends upon the genetic code being passed from parent to offspring. Evolution by natural selection is dependent on traits being heritable. Genetics is very important in human physiology because all attributes of the human body are affected by a person’s genetic code. It can be as simple as eye color, height, or hair color. Or it can be as complex as how well your liver processes toxins, whether you will be prone to heart disease or breast cancer, and whether you will be color
