What genes direct the
Valentin [98]

Answer:

a. hox genes.

Explanation:

HOX genes have the following functions:

  • HOX genes are the homeobox subset.
  • They specify the areas of the embryo's body plan along the animal head-tail axis.
  • They are encoding Hox proteins that specify the position characteristics and ensure that the right structures form at the right position in the body.
  • They regulate high-level executive genes, such as transcription factors and intracellular signaling molecules, which adhere, number, form, and growth to cells.

The vertebrates are highly preserved.

The clusters and other genes occur uninterrupted.

Evolutionary, the heterogeneous regulatory areas between the genes most previously present are larger and more preserved than those present at the other ends of the clusters.

The characteristical feature is that these are homeodomain proteins with a highly preserved area of DNA binding encoded with homeobox gens.

Which of the following statements represent evidence supporting the endosymbiotic theory? Check all that apply.
Tems11 [23]

Answer:

The statement that says " The mitochondrion contains a circular chromosome that has bacterial DNA sequences" is true among the all statement given above.  

Explanation:

The Endosymbiotic theory that is other wise known as the symbiogensis illustrates the occurrence of the eukaryotic cell from the prokaryotic cells. Mitochondria and plastids are the most studied example in support of this theory. This theory explains that the aforementioned organelles are formed as they are taken inside in one another by the prokaryotic cell. Some of the evidences in support of this theory are mentioned below:

  • Phylogenetic similarity between the mitochondria and chloroplast to the proteobacteria and cynobacteria respectively.  
  • Ability of these organelles to divide only through binary fission as the bacterial population.
  • The associated ribosomes are similar to the bacterial ribosomes.  
  • Presence of porins in these organelles similar the bacterial membrane.
