DNA and RNA are molecules that define an organism. DNA is our genetic code, whereas RNA has multiple functions, including being a messenger of the genetic code, a site of protein synthesis, and a transporter of amino acids.Answer and Explanation: The nucleic acids DNA and RNA are polymers c...
The long molecules of DNA, containing your genes, are organized into pieces called chromosomes. Different species have different numbers of chromosomes. Humans usually have 46 chromosomes, two sets of 23, or simply 23 pairs of chromosomes. Chimpanzees have two sets of 24, or 24 pairs of chromos...
Learn the difference between DNA and RNA, learn about the 3 types of RNA and their functions and understand the structure and function of mRNA, tRNA and rRNA. Related to this QuestionWhat are the components of DNA and RNA? What are the components of DNA and RNA molecules? What is the ge...
After gap filling and ligation by DNA ligase III, daughter duplexes are linked at OH as hemicatenanes. TOP3A catalyzes decatenation, allowing daughter molecules to separate. Additional resources Mitochondrial DNA replication in mammalian cells: overview of the pathway Mitochondria MitoLite™ G...
If the two atoms are the same element, it is called ahomonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).Polyatomic moleculeshave more than two atoms, such as water (H2O) and carbon dioxide (CO2). Larger molecules are calledpolymersand may be made of thousands of atoms...
synthesis are glucose and fatty acids. Each glucose molecule produces 2 molecules of pyruvate and 2 molecules of ATP in the cytoplasm, and finally, in mitochondria, the citric acid cycle (also known as the Krebs cycle) produces up to 32 molecules of ATP. Fatty acid oxidation entering the ...
How Purine Bases Form Part of the DNA Double Helix The ladder-like DNA double helix is made up of six molecules. The rungs of the ladder or the steps are made up of the nitrogenous purine bases adenine and guanine as well as the nitrogenous pyrimidine bases thymine and cytosine. The rail...
DNA is the molecule containing genetic information and on the basis of which proteins are synthesised. DNA is made from nucleotide monomers, each themselves made from a phosphate residue, a deoxyribose sugar and a nitrogenous base (either thymine, adenine, cytosine or guanine). ...
James Shapiro's view of evolution is inspired by looking at the molecular mechanisms of mutation. Finding these systems to be intelligent and the mutations non-gradual, Shapiro concludes that neither the role of DNA in development, nor and the role of natural selection in evolution are what we...
What are the types of DNA?DNA:DNA or deoxyribonucleic acid is a double stranded helix (where the two-strand coiled to form a helix structure). It is a type of nucleic acid that carries the genetic material or sequences from one generation to other....
