To build an RNA molecule, the area around a DNA gene must first relax and the two strands must temporarily separate. The separation allows an enzyme complex containing RNA polymerase to fit into a space and attach to the gene's starting area, or promoter, on one of the two strands. The ...
Regarding CRISPR's limitations, it can introduce "off-target effects" if the Cas9 enzyme cuts DNA at unintended places in the genome. This might occur if researchers don't customize the guide RNA sequence for a unique DNA target but instead target a common sequence found in a family of gen...
What molecule is produced by RNA polymerase during transcription? Does a retrovirus have DNA? Does DNA have ribonucleic acid? Are membrane proteins used in DNA replication? Do both strands of DNA contain genes? How does DNA polymerase work?
Replication Two strands of DNA There are two strands that are present in DNA which is replicated as a single molecule. The replication of one strand occurs in a continuous manner which is known as the leading strand. The other strand is known as the lagging strand because the synthesis of ...

31 The number of parasite genomes per sample was quantified using a standard curve generated from purified T. gondii DNA. MRI and Image Analysis After an initial 2.0% to 3.0% isoflurane induction period, all mice were anesthetized and maintained with 1.0% to 2.0% isoflurane in oxygen air ...
Human bone marrow-derived mesenchymal stem/stromal cells (hBM MSCs) have multiple functions, critical for skeletal formation and function. Their functional heterogeneity, however, represents a major challenge for their isolation and in developing potency
How does a chromatid become a chromosome? Before replication, one chromosome is composed of one DNA molecule. In replication, the DNA molecule is copied, and the two molecules are known as chromatids. During the later stages of cell division thesechromatids separate longitudinally tobecome individu...
Genes are units of DNA that serve as discrete pieces of information from the cell, which information can be used to create a certain end product, usually in the form of a protein, mRNA, or other distinct ...
A) How does a tRNA get connected to an amino acid? B) What are the rules governing tRNA-amino acid specificity? Central Dogma: The process of formulating an mRNA copy of DNA is called transcription, and it takes place inside the nucleus. Follow...
