How are DNA and mRNA related?(1 point) Responses If there has been a mutation in DNA, the mRNA will not change. If there has been a mutation in DNA, the mRNA will not change. mRNA is used as a template to make DNA. mRNA is used as a template to make DNA. DNA is used as a template to make mRNA. DNA is used as a template to make mRNA. If there has been a mutation in mRNA, the DNA will not change.
DNA and mRNA are related as DNA is used as a template to make mRNA.
DNA and mRNA are related in that DNA serves as the template for the synthesis of mRNA. This process is called transcription. During transcription, an enzyme called RNA polymerase binds to a specific region of the DNA molecule and synthesizes mRNA by adding complementary nucleotides to the DNA template. The resulting mRNA molecule carries the genetic information from the DNA and serves as a template for protein synthesis during translation. It is important to note that mutations can occur in both DNA and mRNA, but a mutation in DNA will not directly change the mRNA molecule.
DNA and mRNA are closely related and play important roles in the process of gene expression. DNA, or deoxyribonucleic acid, is the genetic material that contains the instructions for the development and functioning of all living organisms. It is organized into structures called genes, which serve as the blueprint for making proteins.
mRNA, or messenger RNA, is a molecule that carries the information from DNA to the ribosomes, where it is used as a template to synthesize proteins. This process is known as transcription. mRNA is generated during a process called transcription, where a section of DNA is transcribed into a complementary RNA molecule.
The relationship between DNA and mRNA can be summarized as follows:
1. During transcription, an enzyme called RNA polymerase binds to a specific region of DNA called the promoter, and separates the DNA strands.
2. One of the DNA strands, known as the template strand, is used by the RNA polymerase to synthesize a complementary mRNA molecule.
3. The mRNA molecule is then modified and processed before it leaves the nucleus and travels to the ribosomes in the cytoplasm.
4. At the ribosomes, the mRNA is read in a process called translation, and the information it carries is used to synthesize proteins.
It is important to note that mutations can occur in both DNA and mRNA. Mutations in DNA can alter the sequence of nucleotides, which can lead to changes in the corresponding mRNA molecule and ultimately affect protein synthesis. However, mutations in mRNA itself do not affect the DNA because mRNA is a transient molecule that is eventually degraded.
In summary, DNA and mRNA are intimately related as DNA serves as the template for mRNA synthesis, which in turn carries the genetic information from DNA to the ribosomes for protein synthesis. Mutations in DNA can affect mRNA, but mutations in mRNA do not alter the DNA itself.
