Answer:
In Manchester England in the 1840's there were factories that used coal which coated the trees. This allowed the darker moths to hide better against the trees than the lighter moths which were eaten by birds.
Explanation:
In humans a gene that has been identified as causing a type of skin cancer is the
<h2>Fatty acid oxidation </h2>
Explanation:
- Activation of fatty acids (palmitate) occurs in the cytoplasm where fatty acids are activated to fatty acyl CoA, reaction catalysed by an enzyme called fatty acyl CoA synthetase
- A specialized carnitine carrier system catalyze transportation of activated fatty acid from cytoplasm to matrix of mitochondria, where carnitine system consists of three proteins:
- Carnitine acyl transferase I located in outer membrane of mitochondria catalyze transfer of carnitine to fatty acyl CoA and produce fatty acyl carnitine
- Carnitine translocase facilitate passive diffusion of fatty acyl carnitine from inter membrane space to matrix located in inner membrane
- Carnitine acyl transferase III located in inner mitochondrial membrane at matrix phase catalyze transfer of CoA to fatty acyl carnitine and regenerate fatty acyl CoA
Hence, the cytosolic and mitochondrial pools of CoA are thus kept separate, and no radioactive CoA from the cytosolic pool enters the mitochondria
Answer:
The lytic cycle has 6 stages: Attachment, penetration, transcription, synthesis, maturation, and lysis.
Explanation:
- Attachment: is the first step of the lytic cycle, and it consists of the attachment of the virus to the host cell, which is the cell that the virus will infect.
- Penetration: once that the virus is attached to the host cell, this penetrates the cell's membrane to introduce its DNA. When the virus DNA is inside the cell's DNA is destroyed.
- Transcription: now the virus has all the machinery to reproduce itself. In other words, the cell starts the transcription of the virus's DNA.
- Synthesis: the cell synthesizes the virus' DNA and proteins.
- Maturation: in this process, the new virus is assembled and ready to be outside the cell.
- Lysis: as the viruses are ready to infect other cells, they go out of the host cell by lysis, which is a process where the membrane is broken and the cell dies to free what is inside.
