THE MOLECULAR BASIS OF INHERITANCE

DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these is NOT true about the nucleus?
A
transcription takes place here
B
translation creates proteins here
C
the DNA is stored here
D
new DNA is made by the process of replication
Explanation: 

Detailed explanation-1: -The nuclear envelope of eukaryotic cells separates the nucleus and cytoplasm. It is thought to partition transcription and processing of messenger RNAs (mRNAs), which occur in the nucleus, from protein synthesis (translation), which is observed in the cytoplasm.

Detailed explanation-2: -So, the correct option is ‘Functioning ribosomes’.

Detailed explanation-3: -The flow of information from DNA to RNA to proteins is one of the fundamental principles of molecular biology. It is so important that it is sometimes called the “central dogma.” Through the processes of transcription and translation, information from genes is used to make proteins.

Detailed explanation-4: -A nucleus is a double-membrane bounded cell organelle present in eukaryotic cells. It controls the functioning of the cell. It contains chromosomes, through which heredity characters are passed from one generation to the other.
