The process of assembling a protein from RNA is called translation. A strand of messenger RNA, or mRNA, travels from the nucleus of a cell to the ribosomes, the site where proteins are assembled.Continue Reading
An mRNA strand is synthesized from a DNA template within the nucleus of an atom in the process called transcription. The mRNA strand passes through the nuclear membrane and travels to a ribosome, where the mRNA strand attaches.
Transfer RNA, or tRNA molecules carry amino acids, the building blocks of proteins, to the ribosome. Many tRNA molecules exist, and each carries a specific amino acid. The tRNA has a side consisting of the anticodon, a three-base code that matches up with a portion of the mRNA molecule called the codon, a series of three bases that stand for an amino acid. The tRNA leaves behind the amino acid it was carrying. The tRNA molecule then goes to find another amino acid. Amino acids are added to the growing protein chain and are held together by peptide bonds.Learn more about Molecular Biology & DNA
The main similarity between transcription and translation is that they are both important phases in the process of protein synthesis. Transcription is the copying of a DNA gene sequence into RNA, while translation is the conversion of an RNA sequence into a string of amino acids that becomes protein.Full Answer >
Ribonucleic acid, known as RNA, is composed of a combination of four different nucleotides: adenine, uracil, guanine and cytosine. Each nucleotide primarily consists of a ribose sugar (five-carbon ring) and a phosphate group.Full Answer >
In eukaryotic cells, the majority of RNA is produced inside the nucleus. Several forms of RNA are synthesized there, including messenger RNA, transfer RNA and ribosomal RNA. Two organelles, mitochondria and chloroplasts, contain their own DNA and reproduce autonomously. Both organelles manufacture ribosomes along with messenger and transfer RNA.Full Answer >
According to Scitable, RNA primase is an enzyme involved in the replication of DNA strands during cell division. It goes over a single DNA strand and creates RNA sequences called primers, which transcribe DNA into RNA. These short sequences of RNA are complementary to the DNA strand they were hovering over, and serve as a template for a new strand of DNA.Full Answer >
