Describe the process of making an mrna molecule in detail

Remember: The making of mRNA is called transcription. mRNA is important because it can leave the nucleus, unlike DNA, so cells can transcribe different RNA's in different cells to make different proteins (cell specification). Transcription takes place in the nucleus of a cell and is made whenever proteins are needed.

There are 3 basic steps of making mRNA:

1. Initiation

The enzyme RNA polymerase binds to the DNA strand and unzips one gene

2. Elongation

RNA polymerase helps free RNA nucleotide base pairs with one strand of the DNA molecule (called a template strand)Adenine (A) pairs with uracil (U) and guanine (g) pairs with cytosine (C)Uracil (U) replaces thymine (T)Ribose sugar is used instead of deoxyribose sugar

3. Termination

RNA polymerase reaches a stop sequence on the DNA and releasesmRNA strand is finished and releasedDNA zips back up

The virus is considered to be are living item since they have hereditary material dnas or rnas. they can imitate and change. they respond to boosts, for example, radiation, chemicals, and warmth. they have antigenic properties. they are proficient to duplicate with a same hereditary constituent.
