Hace 3 días · DNA replication is the process of creating two identical copies of DNA from one original DNA molecule. It occurs before cell division to ensure each new cell has a complete set of genetic information. Transcription, on the other hand, is the process of creating an RNA copy of a gene sequence.
Hace 3 días · cDNA (short for copy DNA; also called complementary DNA) is synthetic DNA that has been transcribed from a specific mRNA through a reaction using the enzyme reverse transcriptase. While DNA is composed of both coding and non-coding sequences, cDNA contains only coding sequences.
Hace 2 días · Cell cycle is the name we give the process through which cells replicate and make two new cells. Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA. So, S stands for DNA synthesis.
Hace 4 días · DNA replication is the process by which a cell duplicates its DNA to produce two identical copies of the genome. The two copies remain paired until cell division, when each of the daughter cells receives exactly one of these copies. The pairing of the two replicated DNAs is mediated by cohesin, a conserved protein complex that stably holds ...
Hace 1 día · DNA replication forks are reported to progress slowly in mouse embryonic stem (ES) cells compared to their non-pluripotent counterparts (Ahuja et al, 2016). Using the DNA fiber assay, we found that the replication fork speed in the E14Tg2A mouse ES cell line was indeed slower compared to the SNL mouse embryonic fibroblast (MEF) line (Fig. 1A).
Hace 2 días · Double-strand DNA breaks introduced by CRISPR-Cas9 allows further genetic manipulation by exploiting endogenous DNA repair mechanisms. CRISPR-Cas immunity is a natural process of bacteria and archaea. [103]
Hace 4 días · Cloning is a word we use to describe a laboratory process of making millions or even billions of copies of a single molecule, most often DNA. It's different from the uses of the term cellular cloning or organism cloning that are used in reproductive genetics.
