It will increase the grasshopper population
Answer:
On the exterior of the cell.
Explanation:
The black spots as mentioned in the given case would appear on the exterior of the cell after three hours, which suggests that the proteins or the enzymes had been discharged from the pancreatic cell. The mentioned method of labeling and then chasing the component is known as a pulse-chase experiment.
In this experiment, the labeled compounds are used to follow the dynamics of cellular pathways and procedures. The molecules in a cell get produced and degraded spontaneously at various rates. These changes in the localization of the molecule and its expression levels with time can be determined by exposing or pulsing cells to a labeled compound.
After this the cells are exposed sequentially to the same compound unlabeled, the process is termed as the chase. The compounds are generally labeled with fluorescent dyes or radioisotopes.
Answer:
a) False.
b) True.
c) False.
d) True.
e) False.
f) True
g) True.
Explanation:
a) The main characteristic of homologous chromosomes is that they have an equal size. There is a difference in size on both chromosomes.
b) In number one, two chromosomes are homologous. In number two also two chromosomes are homologous. On the other hand, the chromosomes at number one and two are different. Each chromosome has two sister chromatids.
c) A DNA molecule has a double helix, that is, two chains. When a DNA chain is broken and a chromatide has a DNA chain, then two chromatids make up a chromosome and a DNA chain, in this way there are eight dsDNA molecules
d) If each chromosome contains a centromere, therefore, there are four centromeres on all four chromosomes.
e) If a chromosome contains four telomeres, therefore there will be sixteen telomeres.
f) The function of cohesin is to regulate the separation of chromatids in the cell division process. When DNA replication is complete, the DNA compacts and condenses to form mitotic chromosomes.
g) The CENPA protein is encoded by the CENPA gene.
