Sort the statements based on whether they describe DNA replication in eukaryotes or prokaryotes. Replication takes place in the

Ilya [14]

In eukaryotes, replication takes place in the nucleus as prokaryotes do not have a true nucleus and replication takes place in the cytoplasm. 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 multiple origins of replication in eukaryotes in contrast to prokaryotes which only has one origin of replication. Lastly, replication in eukaryotes occurs at multiple points along the chromosome; in contrast with prokaryotes where it occurs at just one point on the chromosome.

Free_Kalibri [48]

Answer: Add a different diet and maybe add an animal. If you put a bigger water bowl than the cage will become humid. If you change things about the terrain, its a desert so watering more plants and planting trees will make the ground more fertile to other plants. If you continue to take care of the plants until they are able to grow and reproduce. After enough time, where used to be a desert there will be a forest.

Two autosomal genes, J and K, are 60 map units apart. You perform the following testcross: J K / j k x j k / j k. At what freque

Dmitry [639]

Answer:

J K / j k = 20%

j k / j k = 20%

J k / j k = 30%

j K / j k = 30%

Explanation:

To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.

The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.

So, en the exposed example:

J and K are autosomal genes

J and K are separated by 60 M.U.

60 M.U. means that there is 60% of recombination.

Cross) J K / j k x j k / j k

Gametes) JK Parental jk, jk, jk, jk

jk Parental

Jk Recombinant

jK Recombinant

One map unit equals 1% of recombination frequency. This means that every 100 meiotic products, one of them is a recombinant one.

1 M.U. -------------- 1% recombination

60 M.U. ------------ 60% recombination

30% Jk + 30% jK

100 M.U. - 60 M.U. = 40 M.U.

40M.U.--------------40 % Parental (Not recombinant)

20% JK + 20% jk

Punnet Square) JK jk Jk jK

jk JK/jk jk/jk Jk/jk jK/jk

J K / j k = 20%

j k / j k = 20%

J k / j k = 30%

j K / j k = 30%
