DNA REPLICATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The process of making RNA (i.e. mRNA) from DNA is called
A
Replication
B
Transcription
C
Translation
D
Protein synthesis
Explanation: 

Detailed explanation-1: -All of the RNA in a cell is made by DNA transcription, a process that has certain similarities to the process of DNA replication discussed in Chapter 5. Transcription begins with the opening and unwinding of a small portion of the DNA double helix to expose the bases on each DNA strand.

Detailed explanation-2: -In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.

Detailed explanation-3: -Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template.

Detailed explanation-4: -During transcription, a piece of DNA that codes for a specific gene is copied into messenger RNA (mRNA) in the nucleus of the cell. The mRNA then carries the genetic information from the DNA to the cytoplasm, where translation occurs.

Detailed explanation-5: -mRNA is made from a DNA template during the process of transcription.
