C. DNA is stable, while RNA is less stable. D. DNA can leave the nucleus, while RNA cannot. 相关知识点: 试题来源: 解析 C。DNA 是稳定的,而 RNA 较不稳定,这是正确的。选项 A 中,DNA 含有的是脱氧核糖,RNA 含有的是核糖,说法错误。选项 B 中,DNA 是双螺旋结构,是双链的,RNA 通常是单链...
DNA A In subject area: Pharmacology, Toxicology and Pharmaceutical Science DNA is deoxyribonucleic acid, a linear molecule composed of four monomers: adenine (A), thymine (T), guanine (G), and cytosine (C). From: Retina (Fifth Edition), 2013...
DNA denaturation refers to the process in which the hydrogen bonds and van der Waals interactions that hold the double helix structure of DNA together are weakened, leading to the separation of the DNA strands. This can be induced by various agents such as heat, strong alkalis, urea, and for...
RNA forms in thenucleolus of cells.The nucleolus is a structure within the nucleus of the cell whose purpose is to construct ribosomes (which are made of RNA and protein). After the RNA has been created, it moves to certain regions of the cell's cytoplasm depending on the type of RNA ...
The major difference between DNA and RNA is that DNA is double-stranded and RNA is single-stranded. DNA is responsible for genetic information transmission, whereas RNA transmits genetic codes that are necessary for protein creation.
Why is DNA stable but RNA is not? Genetic Material: The biological material found in the nucleus, mitochondria, and cytoplasm of the cells influencing the structure and nature of the cell is called the genetic material. DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are the most common...
The genetic material of viruses may be single- or double-stranded DNA or RNA.Retrovirusescarry their genetic material as single-stranded RNA and produce theenzymereverse transcriptase, which can generate DNA from the RNA strand. Four-stranded DNA complexes known asG-quadruplexes have been observed ...
The author absolutely found a complementary structure of DD was NnOo, and its associated Initons of H, O-O. And its alkalic procedures could be V, N-N -> A, NNN -> ?, NNNN. Finally he proved four structures of OONN, NNNN, OO and NN, which for RNA IC to use. ...
18.3.10.2.2RNA-based vaccines Cancer RNA vaccines are designed to express thetumor-associated antigen (TAA). The RNA vaccines can deliver a large amount of TAA from a small sample. These vaccines are proved to be important as they reduce the cancertumorburden, target, and lyse them[49]. ...
(Mans et al., 2015). The IMX581 strain expresses a stable integrated copy of codon-optimizedStreptococcus pyogenesspecies of Cas9 nuclease. In contrast to centromeric plasmid-bornecas9expression, this approach allows growth of strains on complex medium, which enables faster growth and efficient ...
