Why are marriages between blood relatives prohibited in the united states and other countries?

Biology
1 answer:
HACTEHA [7]3 years ago
8 0
Marriages or any form of sexual relations between blood relatives is incest and is completely prohibited in the United States and most other countries of the world.

There are two reasons for this:

1. Religious: Most major world religions prohibit marriages between blood relatives. In countries where church and other religious institutions had a strong following, incest remains a crime.

2. Biological: Medical Science has proven that off-springs of close relatives e.g. brother-sister, first cousins and even second cousins have a high chance of genetic mutation which can lead to various health issues. This is the main reason why modern societies prohibit incest

el electrophoresis is normally set up with the negative electrode at the top of the gel and the positive electrode at the bottom
Marina CMI [18]

Answer:

The DNA will still move towards the positive electrode

Explanation:

Gel electrophoresis is a technique which is used by the molecular biologist to separate the fragments of DNA. In the procedure, a DNA sample of a particular concentration of DNA sample composed of a particular length of DNA is loaded into the samples.

The gel is usually set up with the positive electrode at the bottom and negative at the top which by mistake when placed at the bottom and positive at the top.

The DNA will still move from the DNA wells towards the positive side as the DNA moves in the gel as the DNA posses negative charge due to phosphate groups they have and therefore move towards the positive electrode (opposite charge always).

Thus, the DNA will still move towards the positive electrode is correct.

Unlike minerals such as iron and calcium, protein is a macronutrient in the human diet. Why is protein a macronutrient?
Zanzabum

Let's discuss first about difference between micro- and macro-nutrients. Micronutrients are those which are needed in small quantities and their function is not that vast. But macronutrients are the ones which control all the metabolic cycles of the cell, so they are needed in large quantities. This is the basic difference between the two terms.

Proteins are macro-nutrients because they are needed in large amount, as they are involved in some of the most important functions of our body. For example, proteins act as enzymes, involved in immunity, maintaining homeostasis of the body, etc. That is why they are considered as macronutrients.
