THE ROLE OF DNA IS A NUCLEIC ACID THAT CONTAINS GENETIC INSTRUCTIONS FOR THE FUNCTION OF ALL LING THINGS. MRNA IS THE MESSENGER, IT TRANSPORTS PROTEIN AND INFO. THE JOB OF TRNA IS TO READ THE MESSAGES OF NUCLEIC ACIDS AND TRANSLATE IT INTO PROTEINS OR AMINO ACIDS. THE RRNA FORMS RIBOSOMES.
IN THE FIRST STEP OF DNA REPLICATION IS THE DOUBLE HELIX MUSY UNWIND THE SECOND STEP IS NUCLEOTIDES ARE ADDED IN THE CORRECT ORDER THE LAST STEP IS THE NEW SRTAND MUST BE SEALED UP.
The steps to Transcription Initiation. The DNA molecule unwinds and separates to form a small open complex. ... Elongation. RNA polymerase moves along the template strand, synthesising an mRNA molecule. ... Termination. In prokaryotes there are two ways in which transcription is terminated. ... Processing. Ribosomes is consisted of RNA and proteins and is found in all living cells. Codons are located in the DNA strand.
DNA is in a strand called a double helix they pair up like A>T C>G, The steps to central dogma is 1. DNA replication 2. Transcription( RNA) 3. Translation.
