The right answer is B) gene.
A gene, in genetics, is a basic unit of heredity which in principle predetermines a specific trait of the form of a living organism, as defined in 1909 by Wilhelm Johannsen. From the physical point of view, a gene is a fragment of the determined locus of a DNA sequence.
A gene "parameter" the synthesis of a given RNA, by predefining its structure and, therefore, that of the possible protein or possible polypeptide synthesized from this RNA: this is what molecular biology studies .
These two aspects of the notion of gene are supposed to correspond, one at the physical and molecular level, the other at the level of principle and heredity.
The measles, mumps and the rubella vaccine [MMR] is usually given to children twice before the age of 7. The first dose is given between age 12 to 15 months while the second dose is given between the ages of 4 and 6. Many people link the MMR vaccines to autism because of a scientific publication that was published in 1989. The research study reported a link between autism and MMR vaccination. This publication has been discredited.
Also, the period of during which the first dose of the vaccination is usually given coincides with the time when parents usually notice developmental abnormalities in their children.
Answer:
Charge & Size
Explanation:
The smaller the particles, the easier they can diffuse through the cell membrane because they can pass through the channels of the cell membrane,
The lipid layer of the cell membrane is hydrophobic hence‘hates’ charged molecules. Polar or charged molecules will need special channels with trans-membrane proteins to facilitate their movement
