Steven Salzberg 5:06pm EDT Cartoon (c) by Cathy Wilcox Many scientists cheered last year when a federal judge ruled that human genes couldn’t be patented. The case involved Myriad Genetics, which holds the patent rights on two genes, BRCA1 and BRCA2, that are associated with increased risks for breast and ovarian cancer. Thanks to these […]

December 4, 2017 6 min read DNA and mRNA are the two types of most abundant nucleic acids in the cells. Both DNA and mRNA are made up of nucleotides. DNA is the genetic material of both prokaryotes and eukaryotes. It is self-replicative and a new DNA is produced during DNA replication. A gene is a region (locus) or a specific nucleotide sequence on

Colorful DNA Helix Stanislaw Pytel / Getty Images Like the one ring of power in Tolkien’s “Lord of the Rings,” deoxyribonucleic acid (DNA) is the master molecule of every cell. It contains vital information that gets passed on to each successive generation. It coordinates the making of itself as well as other molecules (proteins). If it is changed slightly,
Messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of proteinsynthesis in the cytoplasm (the ribosomes). The molecule that would eventually become known as mRNA was first described in 1956 by scientists Elliot Volkin and Lazarus Astrachan. In addition to mRNA, there are two other major types of RNA: ribosomal RNA(rRNA) and transfer RNA (tRNA)…read more.

Messenger RNA is the single-stranded intermediate molecule that transfers the genetic information from DNA in the nucleus to the cytoplasm where it serves as a template in the formation of polypeptides. Included in this link is free and paid access to several scientific texts providing different perspectives of the structure, role and function of mRNA. …read
