DNA: DNA (Deoxyribonucleic acid) is the molecule that houses an organism's genetic information. DNA is found in the nucleus of every cell in the human body. Chromosomes are thread-like structures that contain DNA. As a result, chromosomes are condensed genetic material. ...
How the structure of DNA contributes to a cell's ability to replicate it? How does the structure of DNA fit its function, especially as it relates to DNA replication? Describe how eukaryotic DNA is arranged in the cell. How does supercoiling take place in eukaryotic DNA?
It was known already that there was an intermediary between the gene, which is DNA, and the protein, which is called mRNA or messenger RNA. We hear about mRNA today because of Covid, but at that time, it was still a mystery. This messenger RNA, which has all the information of the ...
DNA is like a set of instructions that govern the arrangement of amino acids. It is composed of various 3 letter codes, calledcodons. These codons need to be interpreted in order to attain the correct amino acid. Think of it as a password that, if entered correctly, will give you an am...
When a cell makes a particular protein, it must decode accurately the corresponding region of the genome. Additional information encoded in the DNA of the genome specifies exactly when in the life of an organism and in which cell types each gene is to be expressed into protein. Since proteins...
As kidneys have a parallel histological organisation (i.e., functional subunits are arranged in parallel not in series like in bone marrow), the threshold absorbed dose for measuring 50% of kidney dysfunction depends on the volume of irradiated kidney. In EBRT, it is 8 Gy if 100% of the ...
Although herpesvirus DNA is devoid of histones within nucleocapsids, nuclear viral genomes most likely form irregularly arranged or unstable nucleosomes during productive infection, and regular nucleosomal arrays resembling host cell chromatin in latently infected cells. Besides variations in nucleosome ...
made up of nothing but reflex pathways. For example, flatworms and invertebrates don't have centralized brains. They have loose associations of neurons arranged in straightforward reflex pathways. Flatworms haveneural nets, or individual neurons linked together that form a net around the entire ...
Does RNA editing occur in prokaryotes? Typically, how many replication origins are formed in: a. prokaryotes? b. eukaryotes? How are the genome structures of prokaryotes and eukaryotes different? Describe how eukaryotic DNA is arranged in the cell. ...
DNA Structure: DNA is a long complex molecule that's composed of a series of four different nucleotides, adenine, thymine, guanine, and cytosine. The sequence of nucleotides in the DNA strand determines the sequence of nucleotides in the mRNA strands that are produced from it and controls the...
