NCERT Diagram Based Questions Part-3

NCERT diagram based questions are an important part of NEET preparation. These questions require a clear understanding of the concepts and the ability to interpret diagrams accurately. In this article, we will discuss some important NCERT diagram based questions.

1. Explain the process of DNA replication

DNA replication is a fundamental process in which the genetic information is duplicated before cell division. The process of DNA replication can be explained in the following steps:

• Initiation: The process of DNA replication starts at the origin of replication, where the two strands of DNA are separated.


• Elongation: In this process, the DNA polymerase enzyme adds new nucleotides to the existing strand, following the base-pairing rules.


• Termination: When the DNA polymerase reaches the end of the DNA strand, the replication process is terminated and two identical DNA molecules are produced.

2. Explain the process of transcription

Transcription is a process in which genetic information from DNA is converted into RNA. The process of transcription can be explained in the following steps:

• Initiation: The process of transcription starts at the promoter region, where the RNA polymerase enzyme binds to the DNA strand.


• Elongation: In this process, the RNA polymerase enzyme adds new nucleotides to the growing RNA strand, following the base-pairing rules.


• Termination: When the RNA polymerase reaches the end of the DNA strand, the transcription process is terminated and a single-stranded RNA molecule is produced.

3. Explain the process of translation

Translation is a process in which genetic information from RNA is converted into proteins. The process of translation can be explained in the following steps:

• Initiation: The process of translation starts when the ribosome binds to the mRNA molecule at the start codon.


• Elongation: In this process, the ribosome moves along the mRNA strand and adds amino acids to the growing protein chain, following the codon sequence.


• Termination: When the ribosome reaches the stop codon, the translation process is terminated and a complete protein molecule is produced.

In conclusion, understanding the process of DNA replication, transcription, and translation is crucial for NEET preparation. With a clear understanding of these processes and the ability to interpret diagrams accurately, students can excel in NCERT diagram based questions.
