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>.
Hello,
Here is your answer:
The proper answer to this question is "vacuoles are used to clean the cell for example a child cleaning his or her room they would put his or her toys into a closest and that was a vacuole does it cleans up things in a cell and keeps them stored into there like a closest".
If you need anymore help feel free to ask me!
Hope this helps!
Recombination reshuffles alleles of two genes that lie on the same chromosome type, whereas independent assortment reshuffles alleles of two genes that lie on different chromosome types.
Explanation:
Alleles are two forms of same gene, they are located on the same loci of the homologous pair.
Recombination occurs when alleles from two homologous chromosomes get reshuffled during crossing over in meiosis.
Independent assortment refers to the tendency of alleles to be inherited independently from one generation to other.
Answer:
Answer is phloem.
Explanation:
The phloem is responsible for the transportation of food substances or metabolic materials or products, from the point of manufacture , which is the leaves, to all parts of the plant. It also transports mRNA and proteins.
It consists or comprises of different cells which include, fibers, sieve element, sclereids and parenchyma cells.
