Detailed explanation-1: -During transcription, DNA is used as a template to make a molecule of messenger RNA ( mRNA ). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. During translation, the genetic code in mRNA is read and used to make a polypeptide.

Detailed explanation-2: -DNA and Protein Synthesis The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.

Detailed explanation-3: -Definition. Messenger RNA (abbreviated mRNA) is a type of single-stranded RNA involved in protein synthesis. mRNA is made from a DNA template during the process of transcription.

Detailed explanation-4: -The mRNA directs the synthesis of proteins, which occurs in the cytoplasm. mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes. Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide.

Detailed explanation-5: -mRNA is created during transcription. During the transcription process, a single strand of DNA is decoded by RNA polymerase, and mRNA is synthesized. Physically, mRNA is a strand of nucleotides known as ribonucleic acid, and is single-stranded.
