Answer:

the genotype of the bacteria in this E.coli colony is arg^+leu^-met^+

Explanation:

The organism which, due to the lack of particular genes, can not synthesize a particular metabolite or nutrient by itself and needs the nutrient to the growing supplement is called auxotroph. The colony E.coli began to grow on a limited medium with arginine and leucine, and not with arginine and methionine in the above mentioned case. Leucine is therefore a vital metabolite required to grow bacteria and bacteria that do not contain the leu  gene.

Therefore. the genotype of the bacteria in this E.coli colony is arg^+leu^-met^+

Endochondral ossification process involves chondrocytes enlarge and the surrounding matrix begins to calcify, enlarged chondrocytes die, perichondrial cells become osteoblasts and produce a superficial layer of bone, blood vessels grow around the edges of the cartilage, and osteoblasts replace calcified cartilage with spongy bone.

"explain the process of transcription including the three major steps of initiation, elongation, and termination."
4vir4ik [10]
<span>Initiation is when the RNA polymerase separates the strands of DNA at the site of the promoter and connects the RNA nucleotides while they base pair with the DNA template. Elongation is when the polymerase moves downward undoing the DNA and stretching the RNA transcript to the 3 prime end. As this occurs the strand begins to form a double helix. Termination is when the RNA transcript is released and the polymerase disconnects from the DNA.</span>
