Answer:
Nitrogenous bases, the phosphates on the side.
Explanation:
DNA is a chemical in the nucleus that carries genetic codes that will determine a trait.
It is composed of three parts, a four nitrogenous bases, a phosphate group and a deoxyribose sugar.
Together they form a structure that resembles a ladder.
The sides of the ladder are made up of sugar and phosphate backbone.
The rungs are made up of the nitrogenous bases.
Therefore, the nitrogenous base was the one containing the nitrogen.
Another part of the DNA that can be labelled is the Phosphate group found at the sides of the ladder.
Answer:
an opening into a vessel or cavity of the body.
This is possible if the mother does not carry that trait, or has a stronger trait for not carrying that melintin trait.
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 human organs are also called hollow organs because they have an empty tube or pouch. Examples of hollow organs include the stomach, intestine, and the heart.The eye is an organ that is generally considered part of the nervous system.Other organ systems in the human body include the immune system and the lymphatic system.The small intestine is actually much longer than the large intestine.<span>Some scientists say that the liver performs as many as 500 different functions.
