What is a major difference between eukaryotic DNA replication and prokaryotic DNA replication? What is the difference between a gene and a genetic code? Is the gene the instructions for making proteins, or does it contain the ge...
"Gene editing" is a type of genetic engineering in which DNA is inserted, deleted or replaced in the genome of an organism. Which of the following is a proper description of gene editing? A. It is completely safe and has no ethical issues. B. It can only be used on plants, not on...

(C)} of biological macromolecules referred to together as the DNA bases. A gene is a genetic sequence that contains the information needed to construct a protein. All of your genes taken together are 一个基因序列是从四信件字母表腺苷形成的 (串 (A),胸腺嘧啶脱氧核苷 (T),鸟苷 (G),细胞甘 ...

sequence of the glucocorticoid receptor and its relationship with that of the progesterone receptor, oligonucleotides derived from the glucocorticoid response element of the tyrosine aminotransferase gene were tested upstream of a heterologous promoter for their capacity to mediate effects of these two ...
contains many genes (hundreds to thousands) makes up a chromosome. The genes are arranged in a particular sequence and have a particular location on the chromosome (called its locus). In addition to DNA, chromosomes also contain many other chemical components. These chemicals ...
In the early part of the twentieth century, scientists knew whatgenesdid, but they did not know what they were. Francis Crick, one of the codiscoverers of the three-dimensional double helical structure ofDNA, was among the first to propose that a gene was alinearsequence of nucleotides and...
This report shows that the expression of spa (virulence gene encoding the cell-wall-associated protein A) is down-regulated by high osmolarity (1 M NaCl, 1 M KCl or 1 M sucrose) in the wild-type strain and upregulated by novobiocin (a DNA gyrase inhibitor that relaxes DNA). A gyrB142...
aIn this technique of "gene chips", DNA corresponding to thousand of genes are arranged on small matrices ("chips") and probed with labeled cDNA from a tissue of choice. The information is then read by a device to be downloaded to a computer. 在“基因这个技术切削”,对应到一千的脱氧核糖核...
