What are chromosomes made of, from DNA, RNA, and protein, or just DNA and RNA? What are the functions of DNA and through what process does the DNA acquire these functions? What if all the DNA turned into RNA? What is DNA helicase? What does it do?
What is the DNA that has been artificially made using DNA from different sources called? What is the biochemical structure of DNA and how does DNA replicate? What are the types of DNA? What if all the DNA turned into RNA? What are chromosomes made of, from DNA, RNA, and protein, or ...
As already mentioned, the chromosomes are made from the DNA molecule being tightly coiled and tightly packed. Here, the molecule of DNA is coiled around proteins known as histones that provide structural support. Therefore, molecules of DNA as well as histones are the main components of chromosome...
A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Do eukaryotes have plasmid DNA in cytoplasm? DNA in a nucleus, plasmids are found in a few simpl...
What molecule proofreads the new DNA strand to find any mismatched nucleotides during DNA replication? a. Helicase b. Ribozyme c. DNA polymerase d. Transfer RNA DNA replication and DNA repair All DNA polymerases (I, II, and ...
Marking of active genes on mitotic chromosomes. Nature 388, 895–899 (1997). Demonstrates that DNA conformation may contribute to epigenetic memory. Uses potassium permanganate sensitivity mapping to show that DNA at transcription start sites of genes, that are scheduled for reactivation, is ...
Small moleculedrugs: Small molecule drugs are tiny particles that can work on the surface of the cells and can also get into the cell and work on the proteins and signaling pathways inside the cancer cell. Monoclonal antibodies: Monoclonal antibodies are lab-made protein molecules that are too ...
Are homologous chromosomes present in all cells? Describe the role of a cell. What is the difference between a diploid and a haploid? Why can stem cells become any type of cell? What is one way that bacteria can counteract the action of antibodies to generate drug resistance?
What are chromosomes made of, from DNA, RNA, and protein, or just DNA and RNA? Which one is genetic material, DNA or RNA? In molecular biology, what is the other name that is used to refer to the structure of DNA? What is the structure of DNA that determines the expression of a ...
chromosomes What is the structure of the cell membrane? What structure of the cell is made of phospholipids? What lipid do animal cells have inside their cell membranes? What are the fundamental molecules that compose the cell membrane? What organic compounds make up the cell membrane? What is...
