Answer:
Muscle cells and skin cells look and behave differently because their genes are being expressed differently.
Explanation:
- Genes are the sequence of nucleotide that has all the information about the functioning and characteristics of particular cells.
- All genes are actually present in our liver cell but the thing that matter is the gene is expressed differently for different type of functioning.
- So even having the same gene the cells might look different and behave different, its all about turning the gene "on" and "off".
I’m pretty sure it’s because the introns are removed and the Exon’s are kept and joined together to leave the cell. This happens during splicing..
The atoms should onky have same no. of protons+electrons.
Answer:
<u>Transient killer whales prey on marine mammals, while resident killer whales prey on Chinook salmon</u>
Explanation:
Remember, the term "ecotypes" is used to refer specifically to the observable differences found in the various kinds of whales, which includes <em>their breeding populations, their language of communication, social structure, the type of food they eat, and their hunting behavior.</em>
Thus, in the case of transient and resident killer whales in the Northeast Pacific, they are thought to represent different ecotypes rather than different species the Transient killer whales prey (feed) on marine mammals, while resident killer whales prey on Chinook salmon. Also, whales are generally thought to belong to the same species.
Answer:
The new drug will not be effective against the treatment of cancer.
Explanation:
The drug will not be effective against the cancer treatment because the drug will inhibit the dimerization of receptor tyrosine kinase (RTK) but as the Ras has undergone mutation due to replacement of one amino acid, it will be constitutively expressed and the drug is not effective in stopping the Ras functioning.
Thus, Gefitinib cannot work against the cancerous cell as it is not potent to stop the functioning of mutant Ras protein.
