3 lip 2017 · The structure and composition of DNA, RNA, and nucleotides are described. DNA is made of nucleotides containing deoxyribose, while RNA contains ribose. Both DNA and RNA follow Chargaff's rules about base pairing.
5 cze 2012 · Ribonucleic Acid (RNA) • RNA is much more abundant than DNA • There are several important differences between RNA and DNA: - the pentose sugar in RNA is ribose, in DNA it’s deoxyribose - in RNA, uracil replaces the base thymine (U pairs with A) - RNA is single stranded while DNA is double stranded - RNA molecules are much smaller than DNA ...
11 maj 2017 · Messenger RNA (mRNA) carries genetic information from DNA to the ribosomes for protein synthesis. Ribosomal RNA (rRNA) is the catalytic component of ribosomes and is involved in protein translation. Transfer RNA (tRNA) transfers specific amino acids to the growing polypeptide chain during translation.
9 lut 2014 · It also discusses different DNA structures like A, B and Z-DNA and how DNA packages into nucleosomes and chromosomes. For RNA, it notes that it is similar to DNA but contains the sugar ribose and base uracil instead of thymine. Read less
7 kwi 2019 · NUCLEIC ACIDS: STRUCTURE and FUNCTION Nucleotides Since the ribonucleosides have three free hydroxyl groups on their sugar ring, three possible monophosphate can be formed. The ribo and deoxyribo nucleoside 5'-phosphate may be further phosphorylated at position 5' to yield 5'-di- and 5'-tri-phosphates. e.g. Adenosine 5'-phosphate (AMP ...
It differs from DNA chemically in two respects: (1) the nucleotides in RNA are ribonucleotides—that is, they contain the sugar ribose (hence the name ribonucleic acid) rather than deoxyribose; (2) although, like DNA, RNA contains the bases adenine (A), guanine (G), and cytosine (C), it contains the base uracil (U) instead of the thymine (T ...
17 lis 2014 · Assessment Statements. 3.3.1 Outline DNA nucleotide structure in terms of sugar (deoxyribose), base and phosphate 3.3.2 State the names of the four bases in DNA 3.3.3 Outline how DNA nucleotides are linked together by covalent bonds into a single strand
