What is the term for a group of three nucleotide bases in mRNA that specify a particular amino acid to be incorporated into a protein? On a tRNA molecule, what do we call a specific sequence of three nucleotides that is complementary to a codon t...
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 ...
Answer and Explanation:1 A carrier molecule is a protein that helps transport a substance or electrons across a barrier. Carrier proteins usually allow the transport of polar... Learn more about this topic: Carrier Proteins | Definition, Functions & Examples ...
Now, what is DNA renaturation? It’s the opposite process! DNA renaturation occurs when the two single strands of a once double-stranded DNA molecule reassociate with one another — the complementary bases on each strand reform hydrogen bonds with one another, and the DNA double helix reforms....
a functional protein product (FANTOM Consortiumet al., 2005). So not only is the notion of colinearity overly simplistic, but so too is the notion that all genes encode proteins. Many code other types of molecules, liketRNAandrRNA, that have important known cellular functions. Other non-...

In summary, tRNA plays a crucial role in protein synthesis by transporting specific amino acids to the ribosome, where they are assembled into proteins based on the sequence of codons in the mRNA. Each tRNA molecule is activated with a specific amino acid and matches its anticodon with the cor...

The short answer is because the “start codon” AUG codes for Methionine, all proteins must start with Methionine. The longer answer is that mRNA is tranlated (turned into protein) by the ribosome. There’s also a molecule called a tRNA that carries the amino acid about to be added to ...
