Yellow- Green Wavelength of light at peak absorption of 565nm.
Halobacterium is known to be a member of Archaea
and they thrive in very salty environment such as Great Salt lake and Dead Sea. Halobacteria under the process of photosynthesis
with chlorophyll and they make their ATP from the sunlight using bacteriorhodopsin
and halorhodopsin as photosynthetic pigments.
However, photosensory pigements found in
Halabacterium were:
1. photosystem 565 which is used to respond to yellow
–green light in other for cell to find optimum conditions for ATP synthesis and
photophosphorylation and they have peak absorbtion at 565nm.
2. Photosystem 370 nm appears to be responsible
for the protective avoidance of blue/UV light.
Answer: The progeny of this cross do not conform to a 1:1:1:1 ratio
Explanation: This is because out of the 200 total resulting progeny, we must have 50 in each phenotype class to conform with the 1:1:1:1 which is not so as we have 48 in one of the phenotypic class already. Therefore, it did not conform to the ratio.
