The correct answer is "neurons".
Neurons are nerve cells which connect to each other using synapses and form neural networks. They exhibit high levels of specialization and are the primary components of the central nervous system.
Myofibrils are contractile fibers which form the striated muscle cells. Sarcomeres are the structural unit of the myofibrils.
Answer:
They are thick, strong and made up of thousands of tubulin which are spiral in shape.
Explanation:
In eukaryotic cells, they have microtubules which are fibres serving as tracks for cell to cell transport and regulate the shape of a cell.
Microtubules are different from other cytoskeletal filaments because they possesses a cylindrical shape with the tube having a larger diameter of 20-25 nm as compared to microfilament that have a diameter of 3-6 nm.
Microtubules are made of subunits of proteins called tubulin named alpha and beta that is not present in other cytoskeletal filaments.
Many ocean species (especially large ones like whales, sharks, and sea turtles) follow ocean currents to and from their feeding and breeding grounds.
The complete question is:
a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have
A) T2 protein and T4 DNA
B) T2 protein and T2 DNA
C) a mixture of DNA and proteins of both phages.
D) T4 protein and T4 DNA
E) T4 protein and T2 DNA
A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.
A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.
- The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria.
- Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.
- As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.
In conclusion, The new phages produced would have D) T4 protein and T4 DNA.
