About 10% because I know about 90-95% of DNA is junk DNA(doesnt perform serious function)
Transcription is the process in which mRNA is synthesized from DNA template with the aid of RNA polymerase.
Hope this helps!
Answer:
The rate of photosynthesis can be measured in different ways using the scientific method:
- The carbon dioxide being taken up by the plant can be measured.
- The oxygen being produced can be measured.
- The increase in dry mass can be measured.
For example, oxygen can be measured by placing a plant in a water bath containing a capillary tube. The rate of bubbles being formed can be measured. From this, results can be deduced and conclusions can be drawn.
Answer:
Fusarium oxysporum is a fungus which obstructes xylematic ducts in the tomato plant and causes necrosis in the ploem of the plant.
Explanation:
The xylem in a plant is made up of differentiated cells, this cell system performs apoptosis so that the dead cells form a structure called the xylematic ducts. And so it gives way to the creation of a system through which the absorption of water from the soil will be carried out until it reaches the leaves of the plant. What fusarium does when colonizing the xylematic ducts, is to cover them, obstruct them and in this way is that this fungus prevents the absorption of water for the leaves of the plant.
The ploem is another structure in the plant. The phloem has the function of transporting the nutrients made by photosynthesis to those parts of the plant that cannot perform this process that are usually located in the basal or underground part. this will generate that there is no adequate passage of nutrients for the whole plant and its subsequent wilting.
The answer is Cells come only from pre-existing cells.
There are three tenets of cell theory:
1. All living organisms are composed of one or more cells.
2. Cells are the basic structural and functional units in all living organisms.
3. <span>Cells come only from pre-existing cells.
In plants tissue cultures, single cells divide to produce roots, shoots, and leaves. This division suggests there must be some pre-existing cells from which those organs will be produced. So, the tenet that cells come from other cells in cell division is a basis for plant tissue cultures.</span>
