What is a limiting amino acid? When you cook a pot roast, why don't you end up with amino acid soup? Reflect on the strengths of the different types of bonds in a protein. How is DNA related to nucleotides? How are glucose and amino acids reabsorbed by the kidneys? Explain how the...
Amino acids are the monomers of protein. Amino acids are assembled together based on the DNA code by ribosomes inside cells. After the amino acids are linked together the polypeptide is released from the ribosome and can fold into its three dimensional structure to form a functional protein....
A polysome containsa single mRNAand several attached ribosomes, one ribosome for every 100 or so nucleotides. It takes about 30 s for a ribosome in an eukaryotic cell to synthesize a protein containing 400 amino acids. What is it called when the DNA message is copied into RNA? Transcription...
Proteins make up hair nails, bones, muscles, cartilage, skin, and blood. Proteins also make up the building of DNA, cell membranes, hormones, receptors, brain chemicals, and many other molecules in the body. The building blocks of proteins are nitrogen-containing molecules called amino acids. ...
Dark circles under the eyes is a particularly common concern we see in patients visiting our clinics, with patients often remarking that their eyes make them look tired, even when they are not. Dark circles can result from many factors including general
We speculated whether this could be an indirect effect of selection on increased or decreased use of essential amino acids (which covaries somewhat with GC, e.g., all amino acids with T at 2nd position are essential in insects, Tomberlin et al., 2023). However, essentiality was less ...
Carnitineis a substance found in the body that helps turn fat into energy. It’s made up of two amino acids–lysine and methionine–and is naturally found in foods like meat, fish, poultry, and dairy. It plays a key role in moving fat into cells where it can be burned for fuel, whi...
An exon isthe portion of a gene that codes for amino acids. In the cells of plants and animals, most gene sequences are broken up by one or more DNA sequences called introns. What does it mean to inactivate a gene? Inactivating a gene meanspreventing that gene from being expressed as ...
The genetic code is the arrangement of chemical groups that carry a living cell's genetic information. Learn how DNA turns to mRNA and then tRNA, the relation between codons and amino acids, and the universality that makes chimpanzees close genetic cousins. ...
What cellular structure assembles amino acids into polypeptides? A) Golgi bodies B) mitochondria C) ribosomes D) centrioles E) lysosomes What parts of the cytoskeleton help you move chromosomes during the cell cycle? What is the more complex cell type that has a membrane-enclosed nucleus ...
