Ricin comes under the category of functionally related toxins, in a combination known as RIPs (ribosome inactivating proteins). This disables ribosomes and stops the process of protein synthesis.
They directly associate with and inactivate the ribosomes or modify the factors taking part in the process of translation, generally the elongation step. These proteins bring about depurination of adenine at position 4324 in the 28 S rRNA.
This further inhibits the generation of a critical-stem-loop configuration to which the elongation factor is considered to combine at the time of the translocation step of translation. The ultimate outcome of this activity is the complete inhibition of cellular translation.
Answer:
D
Explanation:
Icebergs form when chunks of ice break off from glaciers
Answer:
C
Explanation:
Before the earthquake the gene pool of the parent population was bigger and carried different alleles for a lot of genes.
After the killing of 98% of the population, the surviving one has an incomplete representation of the original gene pool. We can think of this as a gene bottleneck ; the new allele frequencies will be different that the parental population. IE: broadness of stripes has a higher frequency after the earthquake.
Answer:
The correct answer would be allergies.
Allergies is one of the common disadvantages of recombinant DNA technology.
It has been observed that use of genetically modified crops can cause life-threatening allergies.
The possible reason is that the introduction of new genes in the crops may lead to the formation of new proteins our body has never encountered with. These proteins may have a potential to cause allergies or any other life-threatening diseases or complications.
