Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The DNA unwinds. 2. The bonds between the nucleotides breaks. 3. The info. is converted from DNA to RNA. 4. The mRNA carries the code from the DNA in the cell’s nucleus to the parts of the cells that make the proteins. What is this process?

A	Genes are being created.
B	Mutations are occuring.
C	DNA is being copied.
D	Too many things.

Explanation:

Detailed explanation-1: -RNA polymerase II allows unwinding and rewinding of the DNA and thus maintains a constant length of the transcription bubble.

Detailed explanation-2: -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-3: -It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.

Detailed explanation-4: -The Central Dogma of Molecular Biology states that DNA makes RNA makes proteins (Figure 1). The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.
