Deoxyribonucleic acid (DNA) is amolecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known livingorganisms and many viruses. DNA and RNAare nucleic acids; alongside&#...
The double helix structure of a DNA molecule was later discovered through the 60 (experiment) dat a by James Watson and Francis Crick. 61 (eventual), it was proved that DNA is responsible for storing genetic information. 相关知识点:
Figure 1: A single nucleotide contains a nitrogenous base (red), a deoxyribose sugar molecule (gray), and a phosphate group attached to the 5' side of the sugar (indicated by light gray). Opposite to the 5' side of the sugar molecule is the 3' side (dark gray), which has a free ...
5.The first tRNA detached from the its amino acids and he ribosome moves along the mRNA molecule,and a new tRNA with the amino acids will bind with the next codon. 6.The polypeptide is formed gradually until the ribosome reach the stop codon,then the formation of the polypeptide is complet...
Is a molecule (carbohydrates,fat, protein,DNA/RNA) larger in size or a molecular complex (dimers, trimers, tetramers)? Answer and Explanation: A molecular complex is made up of multiple molecules. So assuming you are comparison a single type of mole...
DNA was shown to be responsible for genetic inheritance in 1944. Then, in 1953, its structure was revealed using X-rays. And DNA turns out to be a stunningly elegant molecule. What you’re looking at is the original DNA model currently ...
Rungs are incorporated in a stepwise manner so that each one is addressable. Using fluorescent tags, the nanotube growth was visualized at the single-molecule level. Amani A. Hariri , Graham D. Hamblin & Gonzalo Cosa News & Views | 17 December 2014 Deadly DNA DNA self-assembly has ...
【1】DNA or deoxyribonucleic acid is the molecule that codes genetic information. However, DNA can't directly order a cell to make proteins. It has to be transcribed into RNA orribonucleic acid. RNA, in turn, is translated bycell...
they code. The structure of Each DNA molecule is a long double helix that resembles a spiral staircase and contains millions of steps. These steps of the staircase have pairs of four types of molecules called bases (nucleotides). These bases are paired as follows- the base...
the molecule of which genes are made. dna is present in every cell of the body except red blood cells. dna fingerprinting has been used successfully in various ways, such as to determine paternity where it is not clear who the father of a particular child is. however, it is in the area...
