Only tRNA can come in contact with the ribosomes in the cytoplasm.
Explanation:
The mRNA is responsible for presenting the codons that will be read during translation, that is, it has the coded information for protein synthesis to take place. Given this property, it is easy to understand that these molecules vary greatly in size since proteins of different sizes exist. An mRNA can have from 500 to 6000 different nucleotides. Despite its great importance, mRNA is the least abundant type of RNA.
On the other hand, tRNA is responsible for promoting the transport of the correct amino acid for protein synthesis and is the only RNA that comes into contact with ribosomes in the cytoplasm. It stands out for its clover-like structure and is made up of about 70 to 90 nucleotides. All tRNAs have four characteristic arms, two of which are extremely important: the amino acid arm and the anticodon arm. The amino acid arm binds to the specific amino acid, while the anticodon has the complementary mRNA sequence.
Decline in the global population of amphibians is due to multiple reasons which include:
A moist ecosystem is necessary for amphibians especially for the purpose of their reproduction. The drainage of the wetlands deprives them of their habitat.
Pollutants adversely affects the survival of the gametes, tadpoles or the adult amphibians by acting as toxic agents and inhibiting their normal metabolic function.
Infectious diseases often cause their death resulting their population to decline.
Global climate warming affects their normal metabolic growth and development and hence causes their population to decline.
This is because, If the probes are identical, then the one that feels a larger gravitational force is orbiting closer to Jupiter than the other one is.
The correct option is D. Organisms work best at their optimum temperature and pH, above and below these temperature they will not be able to function as expected. It is possible that the students above use different temperature and pH when they were carrying out their experiments, this will result in different efficiency rate by the yeasts.
