How Would The Dna Sequence Aatcga Be Transcribed To Mrna
Answering the question “How can the dna sequence AATTCGA be transcribed to mrnA?” “, we first have to understand what transcription is. Transcription is the process of copying DNA genetic code onto messenger RNA. RNA polymerase is responsible for this process. DNA bases guanine and adenine always code for cytosine and uracil on messenger RNA. In RNA, thymine is replaced with uracil. This is a result of base pairing rules that determine whether the guanine or adenine is a base for cytosine or uracil.
DNA and RNA are similar in appearance but differ in their function. RNA is a helper for proteins. The ribosome, which is an organelle that produces proteins, copies nucleotide sequences from DNA to RNA. The RNA contains a gene that links to the ribosomes. These ribosomes translate DNA directions into protein.
DNA is translated to RNA “alphabet” to create proteins. To become mature messengerRNA, RNA molecules must go through several steps. mRNA specifies the amino acid sequence of a polypeptide. Mutations affect the amino acid sequence of proteins and genes. Silent mutations do not affect the amino acids sequence during translation.
