Answer:
<u>Organelle</u> is one of the structures a cell uses to live grow and reproduce.
Explanation:
Organelles can be defined as different parts of the cells. Each part of the cell being specialized to perform a specific function or task. The organelles can be found floating in the cytoplasm of the cell. Organelles have a wide number of functions like reproduction of cells, generating energy to perform tasks etc. For example, the nucleus is the hereditary material of the cell and it functions to contain all the genetic information in it for reproduction.
Answer:
The plant would be red.
Explanation:
It would be red because red leaves are a recessive trait which has lowercase b's so if the genotype for the plant is bb, it would be red. If the plant had BB, it would be brown and if it had Bb it would be brown but, it would be a carrier of the red gene.
Answer:
A geneticist has devised a strategy to study protein translocation into the endoplasmic reticulum (ER) in yeast cells. She is interested in two different signal sequences that are thought to operate via slightly different translocation mechanisms. Using genetic engineering, she has fused the first signal sequence to a protein whose cytosolic expression is absolutely necessary for cell survival in the selective medium, but is inactive when in the ER. In the same cell, she has also fused the second signal sequence to a toxic protein whose cytosolic expression leads to cell lysis but is harmless when in the ER. Whereas wild-type cells undergo lysis upon the expression of these fusion proteins, she has been able to identify viable mutants, each of which has a loss-of-function mutation in a gene encoding a protein involved in membrane translocation. The products of these genes are probably ...
Explanation:
Involved in the transport of proteins with the first signal sequence but not the second one.
