Which flow chart is accurate?

DNA → RNA → protein

DNA → protein → RNA

RNA → DNA → protein

RNA → protein → DNA

The correct option is A) DNA → RNA → protein

Explanation:

Central Dogma can be described as the process under which the processes of transcription and translation are focused. It is the process by which particular parts of DNA or particular genes make up the specified proteins which are required.

The conversion of DNA into RNA is known as transcription. This process occurs in the nucleus. The conversion of mRNA into proteins is termed as translation. This process occurs in the ribosomes of the cytoplasm.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
