Here is the simple answer:
It basically rips the DNA into pieces and those pieces are placed into the gel. The gel has holes throughout the contaioner and allowing the DNA pieces to wiggle through. These are pulled by an electric potential (or voltage) that attracts the DNA pieces. The larger the piece of DNA the shorter distance it will travel through the gel.
Answer:
Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene
Answer:Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of the curvature of spacetime caused by the uneven distribution of mass.
Explanation:
The allele that can mask the presence of another allele is called dominant. The allele that is masked is recessive and if both alleles can be detected in the phenotype, then they are codominant. If they produce an intermediate phenotype like pink instead of red or white, then they have a relationship of incomplete dominance.
Answer:
A homozygous recessive pea plant would have genotype rr and the heterozygous plant would have genotype Rr. So after the crossing between these two individuals occurs the two offspring produced would be heterozygous and the other two would be homozygous recessive.
R r
r Rr rr
r Rr rr
Therefore the genotype ratio would be 1:1 and the phenotypic ratio would also be 1:1 in the F1 generation because half would be round and half would be wrinkled.
