Deoxyribonucleic acid, or DNA, is a molecule containing instructions on how to make a living organism. Its structure and sequence instruct the cell on how to make proteins, which go on to carry out important functions of a cell. Many cells form tissues, many tissues form organs, and all th...
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 ...
How are genes transcribed in eukaryotes? How do cells use the base sequence of a DNA molecule to produce a polypeptide? Describe how eukaryotic DNA is arranged in the cell. During DNA replication, how are the new nucleotides added to the template strand?
What sort of point mutation would occur in a DNA molecule that would suddenly create billions of new neurons and wire them correctly?* The current theory of evolution does not predict how this could happen. One line of current research is looking at the effect of very small changes in DNA ...
LAMC2 subunit is a compound of Laminin-5 molecule, which is a subepithelial basement membrane isoform [60]. LAMC2 overexpression was also found in cancer cells and therefore the correlation between tumorigenesis and tumor spread and the protein levels was investigated. It was reported that LAMC2 ...
of DNA. In response, the cell attempts to glue the strands back together, but it uses afault-ridden processthat often introduces mutations. For instance, it may add a few extra letters. This change often deactivates the gene, making CRISPR editing a simple strategy to switch off genes. ...
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...

Why is the DNA Sequence of a gene not equivalent to the RNA sequence of the same gene in eukaryotes? What processes generate these differences? What makes one DNA molecule different from another? What is the relationship between DNA and chromatin?
