Now we will know more about their types and their role in the biology of an organism. Following are the important differences between DNA and RNA: DNA and RNA Difference. Ribosomal RNA (rRNA), transfer RNA (tRNA), and messenger RNA (mRNA) are the main types of RNA. Some of them try to smuggle the antigen into the body, others use the body’s own cells to make the viral antigen. Adenine and guanine are purines, cytosine and uracil are pyrimidines.A phosphate group is attached to the 3' position of one ribose and the 5' position of the next. In prokaryotes, mRNAs contain an exact transcribed copy of the original DNA sequence with a terminal 5′-triphosphate group and a 3′-hydroxyl residue. Messenger RNA (mRNA): It is a long RNA which constitutes 2-5% of the total RNA content. This is a type A or Family A polymerase enzyme that was initially isolated from E. coli and most abundantly found in E. The RNA polymerase proceeds to read one strand moving in it's 3'→ 5' direction. messenger RNA, code for proteins. The … messenger. ; Its main function is excision repair of DNA strands from the 3′-5′ direction to the 5′-3 direction, as an exonuclease. The mRNA is made up of nucleotides found in the nucleus that come together to make a complementary sequence to the DNA found there. DNA Polymerase I. Terms in this set (9) mRNA. We report a systematic unbiased analysis of small RNA molecule expression in 11 different tissues of the model organism mouse. The four nucleotides are adenine, cytosine, guanine and uracil.
