WebEach dash of the X shape marks the repetition of atoms, or atomic repeats, in DNA. Therefore, based on the distances between the dashes, Franklin determined the distance between nucleotides, the smallest repeating units in DNA. WebFor example, adenine (A) is always paired with thymine (T), and cytosine (C) is always paired with guanine (G). This is because hydrogen bonds hold the nitrogen atoms together. This arrangement helps keep the DNA molecule stable and intact and makes sure that genetic information is stored and passed on correctly. 9) ATCCAG.

WebMar 22, 2024 · Each strand of a DNA molecule is composed of a long chain of monomer nucleotides. The nucleotides of DNA consist of a deoxyribose sugar molecule to which is attached a phosphate group and one of four nitrogenous bases: two purines ( adenine and guanine) and two pyrimidines ( cytosine and thymine ). WebHumans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 13, one copy inherited from each parent, form one of the pairs. Chromosome 13 is made up of about 115 million DNA building blocks (base pairs) and represents between 3.5 and 4 percent of the total DNA in cells. how is monkeypox mainly spread

WebDNA (deoxyribonucleic acid) is a very big molecule (a macromolecule) made up of billions (yes, billions!) of just five types of atoms: hydrogen, oxygen, carbon, nitrogen and … WebAdenine (/ ˈ æ d ɪ n ɪ n /) (symbol A or Ade) is a purine nucleobase.It is one of the four nucleobases in the nucleic acids of DNA, the other three being guanine (G), cytosine (C), and thymine (T). Adenine derivatives have various roles in biochemistry including cellular respiration, in the form of both the energy-rich adenosine triphosphate (ATP) and the … WebJan 30, 2024 · Examples range from simple molecules like CH 3 NH 2 (methylamine) to large molecules like proteins and DNA. The two strands of the famous double helix in DNA are held together by hydrogen bonds between hydrogen atoms attached to nitrogen on one strand, and lone pairs on another nitrogen or an oxygen on the other one. how is monkeypox being spread
