Which mode of transfer does not occur?

a)
dna > rna

b)
rna > protein

c)
dna > protein

d)
mrna > protein

The correct option is C

Explanation:

The central dogma involves conversion of DNA to protein. The DNA either undergoes transcription to form RNA or replication to form a new DNA. When transcription occurs, RNA is formed which can then be translated into protein. Consider the illustration below

DNA ⇒ RNA ⇒ Protein

There are three types of RNA

Of these three RNAs, the mRNA is the one translated into protein with the aid of the remaining two.

From the above, it can be deduced that DNA cannot be directly converted into protein.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
