Option A, The curiosity rover found sulfur compound in rocks
Explanation:
NASA had send Curiosity rover to Mars. After this accomplishment, lot of information about the rust colored planet has been obtained such as type of landscape, traces of water etc.
However detailed information about the planet has been obtained through Curiosity's Sample Analysis at Mars (SAM) which gave the information about the mineralogical and chemical composition of the planet. During this analysis, sulfur was found and hence option A is correct
This might be slightly wrong, it was somewhat difficult for me to keep up with which letter I was on. Adenine always pairs with Uracil and Guanine always pairs with Cytosine.
A bacteriophage is an infection that attacks bacteria. At the point when the tail strands identify an objective host the bacteriophage to the cell, injected its DNA, and utilizations the microscopic organisms' apparatus to reproduce.<em></em>
<em>T4 is a sort of bacteriophage that infects of E. coli. </em>
The bacteriophage T4 capsid is a prolonged icosahedron,120 nm long and 86 nm wide, and is worked with three essential proteins such as gp23*, which shapes the hexagonal capsid cross section, <em>gp24*, </em>which structures pentamers at eleven of the twelve vertices.
<em>gp20, </em>which frames the extraordinary dodecameric entry vertex through which DNA.
T4 DNA Ligase is ligation catalyst which utilized the parts of DNA by the catalyzing between <em>compared 5'phosphate and 3' hydroxyl ends</em> and phosphodiester bonds in the double stranded DNA utilizing ATP as a coenzyme.
