In eukaryotes, <em>replication takes place in the nucleus</em> as prokaryotes do not have a true nucleus and <em>replication takes place in the cytoplasm</em>. The nucleus of the eukaryotes is the location where genetic material (DNA) is found; in prokaryotes, the genetic material is condensed in the cytoplasm called the nucleoid. There are multiple replication forks or <em>multiple origins of replication </em>in eukaryotes in contrast to prokaryotes which only has <em>one origin of replication. </em>Lastly, replication in eukaryotes <em>occurs at multiple points along the chromosome; </em>in contrast with prokaryotes where it <em>occurs at just one point on the chromosome.</em>
I) Locus- the chromosomal site where a specific gene is located. A locus is a fixed position on a chromosome, like the position of a gene or a marker. Each chromosome carries ,many genes; human's estimated haploid (n) protein coding genes are about 20,000, on the 23 different chromosomes.
ii) Interference; the observed double crossover frequency differs from the expected double crossover frequency. Cross over interference is used to refer to the non-random placement of crossovers with respect to each other during meiosis. It results in widely spaced crossovers along chromosomes. Interference may exert its effect across whole chromosomes. As chromosomes in many eukaryotes are large, interference must be able to act over megabase lengths of DNA.
iii) Linkage- the tendency for genes located in close proximity on the same chromosome to be inherited together. Normally when two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.
iv) Recombination- the process by which a new pattern of alleles on a chromosome is generated. Genetic recombination is the production of offspring with combinations f traits that differ from those found in either parent. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes.
Answer:
White owl is the symbol of wisdom. The snowy owl is the symbol of endurance. It represents big dreams along with the ability to achieve them. It is the sign of new beginnings and moving forward with all might.
Percent error is calculated by the expression:
%error = |actual value - observed value| / actual value x 100
We calculate the error of the values as follows:
<span>a. 23.487 cm
% error = |</span><span>23.490 - 23.487| / 23.490 x 100 = 0.013%
</span><span>
b. 23.493 cm
</span>% error = |23.490 - 23.493| / 23.490 x 100 = 0.013%
<span>
c. 23.516 cm
</span>% error = |23.490 - 23.516| / 23.490 x 100 = 0.11%<span>
d. 23.501 cm
</span>% error = |23.490 - 23.501| / 23.490 x 100 = 0.05%<span>
e. 23.477 cm
</span>% error = |23.490 - 23.477| / 23.490 x 100 = 0.055%
