31 Οκτ 2023 · The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the chloroplasts and mitochondria.
The mRNA specifies, in triplet code, the amino acid sequence of proteins; the code is then read by transfer RNA (tRNA) molecules in a cell structure called the ribosome.
23 Αυγ 2020 · Three differences between DNA and RNA are that DNA uses the base thymine while RNA uses uracil, DNA uses the sugar deoxyribose while RNA uses ribose, and usually DNA is double-stranded and RNA is single-stranded.
RNA polymerase II transcribing DNA into RNA. A RNA polymerase is composed of several proteins. It unwinds DNA strands (violet) and builds RNA (red) out of the nucleotides uridine, adenosine, cytlidine and guanosine monophosphate. dna rna protein stock pictures, royalty-free photos & images.
