$$\text{DNA} \xrightarrow{\text{transcription}} \text{RNA} \xrightarrow{\text{translation}} \text{Protein}$$

Question 1

Which process is depicted as the first step in the central dogma of molecular biology, as shown in the diagram?

Accepted Answer

Transcription of DNA into RNA

Question 2

According to the central dogma illustrated, what is the correct sequence of information flow in a cell?

Accepted Answer

DNA → RNA → Protein

Question 3

In the context of the central dogma, which enzyme is responsible for synthesizing RNA from a DNA template?

Accepted Answer

RNA polymerase

Question 4

Which of the following best describes the process of translation as shown in the central dogma diagram?

Accepted Answer

Decoding mRNA to assemble amino acids into a protein

Question 5

If a mutation occurs in the DNA sequence, how might this affect the final protein product according to the central dogma?

Accepted Answer

It may change the mRNA sequence, potentially altering the amino acid sequence of the protein

Question 6

Which of the following equations best represents the central dogma of molecular biology?

Accepted Answer

$$	ext{DNA} \xrightarrow{	ext{transcription}} 	ext{RNA} \xrightarrow{	ext{translation}} 	ext{Protein}$$

Question 7

Which molecule acts as the direct template for protein synthesis in the central dogma?

Accepted Answer

mRNA

Question 8

What would be the immediate consequence if transcription did not occur in a cell?

Accepted Answer

No mRNA would be produced, so translation could not occur

Question 9

Which of the following statements is supported by the central dogma diagram?

Accepted Answer

Information flows from DNA to RNA to protein

Question 10

Which process ensures that the genetic code is accurately passed from DNA to RNA?

Accepted Answer

Transcription
