Answer:
1/4
Explanation:
Given that the F2 cross produces offspring according to the expected 9:3:3:1 ratio.
YyRr X YyRr:
Let us break the dihybrid cross into individual monohybrid crosses.
Yy X Yy :
Y y
Y YY Yy
y Yy yy
2/4 or 1/2 of the offspring are heterozygous for the trait.
Similarly, in Rr X Rr cross, 1/2 of the offspring are heterozygous for the trait.
Together, 1/2 * 1/2 = 1/4 of F2 plants are expected to be heterozygous for both traits.
The answer is Lactobacillus because it is a bacteria and that's what prokreatic cells are.
<span>the number of sets of chromosomes within a cell or organism. Each set is designated n so one set is n is haploid, two sets is 2n is diploid, three sets is 3n is triploid, four sets is 4n is tetraploid, etc. Also, unspecified multiple sets (but more than two) is polyploidy, and extremely large number of sets may be designated by number (for example 15-ploid for fifteen sets). The number of chromosome sets that make up the [[genome of an organism, e.g. [[polyploidy.</span>
Answer:
The pre-mRNA molecules undergo three main modifications. These modifications are 5' capping 3' polyadenylation and RNA splicing which occur in the nucleus before RNA is translated.
Explanation:
Answer:
The equation of the photosynthesis becomes reverse in the cellular respiration. In both process the reactants and products are altered.
Photosynthesis is the light harvesting process. Here the plants use water, carbon dioxide, light as raw material to produce glucose, energy and oxygen. This process occurs in the chloroplast of the leaves. In this reaction the products are oxygen and glucose.
In cellular respiration, the byproduct of photosynthesis i.e. glucose is oxidised to release energy and carbon dioxide, along with the ATP molecules. This reaction is the reverse reaction of the photosynthesis.
In cellular respiration the product of the photosynthesis becomes becomes reactant.
The cellular respiration occurs in the cytoplasm of the cell and involves many steps to release energy. The various cellular respirations are glycolysis, kreb's cycle, electron transport chains, etc.
