<h3>What is the Hox genes and evolution?</h3>
Hox proteins are a family of transcription factors that have undergone extensive conservation. They were first identified in Drosophila for their crucial functions in regulating segmental identity along the antero-posterior (AP) axis.
The regionalization of the AP axis and changes in the expression patterns of these genes have been strongly correlated during the past 30 years across a wide range of evolutionarily distinct species, indicating that Hox genes have been essential in the evolution of new body plans within Bilateria.
Despite this extensive functional conservation and the significance of these genes for AP patterning, many important concerns about Hox biology remain.

<span>Answer:
Is grossly bloody appearance and has a pH of 6
Rationale: Leakage of CSF from the ears or nose may accompany basilar skull fracture. it can be distinguish from other body fluids because the drainage will separate into bloody and yellow concentric rings on dressing material which is also known as halo sign</span>
Answer: The nucleas contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.
Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other.
