Which of the following statements is true about Tiktaalik?
yawa3891 [41]

Tiktaalik is a transitional fossil which shows how fish evolved into amphibians and reptiles. So the correct option is B.

What is Tiktaalik?

Tiktaalik is a direct ancestor of tetrapods or four-legged animals. It is an extinct fish-like animal and it lived on earth 380-385 million years ago (Devonian period).

The word Tiktaalik is derived from the <em>Inuktitut</em> language which loosely translates to large freshwater fish. This animal had characteristics of both fish and tetrapod and is therefore called the link between these two kinds of animals.

The characters resembling fish are gills and scales and the characters resembling tetrapods are rib bones, movable neck and lungs. There are characters that are a mix of both tetrapods and fish. These are bones and joints in limbs but fish-like fins instead of feet or hands.

where would you find the precursor of a mitochondrial matrix protein in the following types of mitochondrial mutants: (a) a muta
Reil [10]

The precursor of a mitochondrial matrix protein is found in a mutation in the tom22 signal receptor.

Tom22 and Tom20 function as N-terminal matrix targeting sequences' outer mitochondrial membrane receptor proteins. The buildup of mitochondrial matrix-targeted proteins in the cytosol due to a malfunctioning Tom22 receptor protein may be followed by cytosolic turnover of these proteins.

The N-terminal sequence, which directs the protein to mitochondria and is proteolytically processed upon import3, is produced in approximately 70% of mitochondrial precursor proteins3. To get to the matrix, they must pass via the TIM23 and TOM complexes on the inner and outer membranes, respectively.
