What is the function of mRNA?

What is the function on tRNA?

Describe what happens during transcription.

Describe what happens during translation.

Explain how DNA is used to make a protein.

mRNA

Messenger RNA is used to copy and encode genetic information from DNA base pairs by forming complementary strand of RNA molecule from the nucleus of the cell to the cytoplasm.

tRNA

Transfer RNA reads sequence of nucleotide from messenger RNA and translate them into proteins or amino acids during proten synthesis.

Transcription

This is the first step in gene expression where information from DNA is copied into a complementary strand of RNA molecule using RNA polymerase enzyme.

Translation

Messenger RNA made from the process of transcription travels to the ribosomes in the cytoplasm where proteins are produced using transfer RNA to copy the information.

The use of DNA to make proteins.

Through gene expression (central dogma of biology), the DNA molecule carries information, a gene code, in form of base pairing sequences that are transcribed to RNA and further translated to functional proteins or amino acids.
