Answer:
If a DNA molecule has 30% Adenine the percentage of the other bases is Thymine: 30% Cytosine: 20% Guanine: 20%.
Explanation:
When the percentage that a base has in a DNA molecule is given, the percentage of the other bases can be known using the Chargaff's base pair rule.
A DNA molecule has the information of the genome of a living being, according to a specific sequence of its nitrogenous bases adenine, guanine, cytosine and thymine.
Chargaff was able to establish that in a DNA molecule the ratio of purine : pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, taking into account the complementarity of bases.
Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:
- <em>Adenine 30%.
</em>
- <em>Thymine 30%.
</em>
- <em>Cytosine 20%.
</em>
- <em>Guanine 20%.
</em>
- <em>Total ..... 100%
</em>
In this case, the <u>Chargaff rule is useful to determine the percentage of nitrogenous bases that exist in a DNA molecule, knowing the percentage of a single base</u>.
Density can be useful in identifying substances. It is also a convenient property because it provides a link (or conversion factor) between the mass and the volume of a substance. Mass and volume are extensive (or extrinsic) properties of matter - they depend on amount.
Answer:
Yes they do their a bit longer
That prokaryote is <span>Psychrophile, a coccus and a decomposer.
1)The prokaryote is</span> shaped like a ball or generally has a round shape so it's called a coccus (Cocci in plural). This is one out of three terms, that are used to name bacteria. The other ones are bacillus and spiral. For example, Staphylococcus aureus is a bacteria that has a round shape but it's formed by more that one ball, that together look like a bunch of grapes.
2) This organism lives deep under the water, so it's named as a psychrophile or cryophile. This means they can live and reproduction at extremely low temperatures(-20ºC), and some places with those temperatures are the polar regions and the deep sea.
3) This prokaryote consumes dead organisms so it's classified as a decomposer.
Decomposers are organisms that can break down dead or decaying organisms. The process is an essential part of the nutrient cycle and is important for recycling the organic matter that occupies space in the biosphere.
