Explain how a genetic map (in map units) is related to actual physical distance (in base pairs of DNA).
antiseptic1488 [7]

Explanation:

A map unit [or centimorgan (cM)] is a unit for measuring genetic linkage. It is defined as the distance between chromosome positions for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01. <em>Its relation with actual physical distances is inconsistent </em>because the number of base pairs to which it corresponds varies widely across the genome, it also depends on whether the meiosis in which the crossing-over takes place is a part of male or female genes (female genome is 4782 cM long, while the male genome is only 2809 cM long).

I hope you find this information useful. Good luck!

What is a possible explanation for why bacteria lack ether-linked cell membranes
oee [108]

Answer:

Because they do not live in the extreme environments.

Explanation:

Cell membrane has a vital role in separating the external environment of cell from its external environment. Just like eukaryotic cell, cell membrane of bacteria is also composed of proteins and lipids (phospholipids).

If we compare the structure of ancient bacteria's and modern bacteria's cell membrane then we notice that in  archaebacteria or ancient bacteria the phospholipids of cell membrane are linked with ether (means they have glycerol backbones). whereas in modern bacteria they are linked through ester linkages.

So, the stronger glycerol backbones give the archaebacteria more stable cell membranes through which they are able to resist harsh environmental stresses like salt lakes, volcanic stress, boiling mud and hot springs. As modern bacteria do not always have to live under such stresses thats why they donot have ether-linked cell membrane.

Hope it helps!
