Answer:
B. introns; exons
Explanation:
Related genes from different organism usually translate to proteins of indispensable functions. This means that the proteins must be similar in terms of amino acids produced. Therefore the coding region must be highly conserved. These can be found in the introns. Conversely, exons are not a part of the coding sequence and therefore not required for translation. These sequences may be less conserved.
Answer:
There is no diagram in this question but the question can still be answered without it.
B. hold the cell membrane together, and proteins move chemicals across the cell membrane
Explanation:
The fluid mosaic model, which describes the structure of the cell membrane, reveals that it contains both lipids and protein constituents. These components, however, performs different functions in the cell membrane of organisms.
The lipid component of the cell membrane, which comprises of glycolipids and cholesterol, hold the cell membrane together while proteins called transport proteins help move chemicals across the cell membrane.
Answer:
The DNA testing process is comprised of four main steps, including extraction, quantitation, amplification, and capillary electrophoresis.
Explanation:
1. Separate white and red blood cells with a centrifuge.
2. Extract DNA nuclei from the white blood cells. ...
3. Cut DNA strand into fragments using a restriction enzyme.
4. Place fragments into one end of a bed of agarose gel with electrodes in it. 5. Use an electric current to sort the DNA segments by length.
All the statement above are very true of what virus structure constitute.
This goes to say that viruses:
- use DNA as their genetic material.
- have a phospholipid bilayer envelope.
- lack organelles, ribosomes, and a plasma membrane.
- have a capsid.
- require a host for replication.
<h3>What are viruses?</h3>
Viruses are seen and considered as the border line between living and non living things.
- Viruses are living when they are inside another living organism. They are the smallest known microorganisms.
- However, they are non-living when they are outside the system of a living thing
