Marina CMI [18]

Answer:

The correct answer would be Both types of fingerprints can often be easy to obtain from the crime scene.

DNA fingerprinting is a technique used for a paternity test and in establishing a link between the biological evidence and suspect in the crime, identification of dead bodies et cetera.

It is based on the similarities and differences associated with the DNA sequence of organisms especially the non-coding or junk DNA.

The DNA fingerprints are developed in labs, they are not found at crime scenes.

At the crime scene, pieces of biological evidence such as blood, skin, hair et cetera are taken from which DNA could be extracted.

liberstina [14]

Answer:

In the nucleus, mRNA is formed from free floating nucleotides in a process called transcription. This process requires the enzyme RNA polymerase II.

Explanation:

mRNA (or messenger RNA) is transcribed from a DNA template in the nucleus. This uses the enzyme RNA polyermase II, which copies the DNA sequence to the RNA sequence using nucleotides. The RNA polymerase binds at gene promoters, where it transcribes the RNA by reading the DNA sequence until it reaches the termination signal to stop transcribing.

After this, the RNA molecule moves to the cytoplasm where it can be translated into protein.
