Proteins

Proteins do not replicate on their own, unlike DNA or RNA. They also do not store genetic information like nucleic acids do. Additionally, proteins do not have a role in directly passing on hereditary traits to offspring.

DNA ligase joins the Okazaki fragments together on the lagging strand during DNA replication. It catalyzes the formation of phosphodiester bonds between the fragments to create a continuous strand.

Integral membrane proteins include transmembrane proteins, which span the entire lipid bilayer, and lipid-anchored proteins, which are attached to the membrane through lipid molecules. These proteins are essential for various cellular functions such as cell signaling, transport, and structural support. Examples include ion channels, transporter proteins, and receptors.

yes, transmembrane proteins have both polar and non-polar regions. This is because these proteins are dispersed through the membrane almost like pieces of stones. So, to be inside the hydrophobic region of the phospholipid bi-layer AND also outside of it in the water or aqueous solution they transmembrane protein needs to be amphipathic.

The Golgi apparatus is responsible for tagging proteins with molecular markers that determine their final destination within the cell or outside of it.

Protein-protein interaction is a delicate and crucial for the normal cell function such as signalling, replication, cell cycle and so on. It happens with non covalent interactions such as ioni, hydrogen, wanderwall's bonding. protein protein interaction are species specific in terms of host-pathogen proteins.

Proteins are used by organisms for a variety of functions, including serving as enzymes to catalyze chemical reactions, providing structural support for cells and tissues, and acting as signaling molecules to regulate processes within the body. They are also essential for the growth, repair, and maintenance of tissues in the body.

Two proteins found in meat are myosin and actin. Myosin is a motor protein that is critical for muscle contraction, while actin is a structural protein that helps provide shape and support to muscle fibers.

Some proteins can act as biological buffers because they contain ionizable functional groups that can accept or donate protons to help maintain a stable pH in a cell or organism. These proteins can help regulate and minimize changes in pH by absorbing or releasing hydrogen ions as needed. This buffering capacity is crucial for maintaining proper enzyme activity and other biological processes that are pH-sensitive.

Proteins are solute molecules found in a dissolved form in buffer. Proteins can be crystallized to form a crystal (solid) by evaporation. This method is used in protein X-ray crystallography to solve its 3D structure.

Proteins are biomolecules made up of amino acids and are synthesized by cells. Proteins play many vital roles in cells, such as structural support, catalyzing biochemical reactions, and cell signaling. While proteins themselves do not have cells, they are essential components of all living cells.

Yes they do. proteins are macromolecules that are made up of amino acids connected with peptide linkage. Sulfur containing amino acids such as cysteine, methionine are also can be present in proteins. they are involved in the formation of disulfide linkage in the protein molecule.

Polytrophic proteins are proteins that can interact with multiple ligands or substrates, each leading to different downstream effects. This versatility allows these proteins to regulate multiple cellular processes and pathways simultaneously. Examples include transcription factors that can influence the expression of multiple genes in response to different signaling molecules.

We have to clearly understand the concept that enzymes are actually, chemically proteins. There are enzymes that are involved in proteins production (peptidyl synthetase), lipid or nucleic acid formation. So a protein can help in forming other protein or enzymes. Most important thing is, all proteins are coded in DNA.

Sperm or spermatozoa are male germ cells that has one set of chromosomes, known as "n" (unlike somatic cells that has "2n"). Semen (the liquid in which sperms are dispersed) do contains protein albumin and free amino acids. They also do have potent antimicrobial proteins.

Proteins are synthesized by ribosomes in a process called translation, where messenger RNA (mRNA) provides the template for assembling amino acids into a polypeptide chain. Transfer RNA (tRNA) molecules bring specific amino acids to the ribosome based on the mRNA codons, and the ribosome catalyzes the formation of peptide bonds between the amino acids, ultimately leading to the formation of a functional protein.

abbr. for keratin-myosin-epidermin-fibrinogen group; a group of proteins that have in common an α-type X-ray diffraction pattern. Some of these may show a β-type pattern in some conditions. Silk fibroin, which normally occurs with a β structure, is often included in the KMEF group.

There are a few RNA catalysts are known, but the majority is only proteins. Biochemical reactions are speed by enzymes by lowering the activation energy. Enzymes like other proteins are coded in DNA.

Enzymes are proteins because they are made up of amino acids linked together in a specific sequence, forming a complex three-dimensional structure that allows them to catalyze chemical reactions. This structure is crucial for the enzyme's function and specificity in recognizing and binding to their substrate molecules. Enzymes can be denatured by changes in pH or temperature, highlighting their protein nature.

Proteins differ each other in their amino acid composition and the number of amino acids that form it. Not all the proteins are the same, although they are all made up of amino acids. the sequence of amino acids is determined by the mRNA which is transcribed by DNA in the nucleus.

Yes, proteins can attract water molecules through a process called hydration. Water molecules are attracted to the polar regions of proteins, such as the amino and carboxyl groups, forming hydrogen bonds. This hydration can influence the structure and function of proteins.

Yes about 8-10% of protein fond in maize depending on their variety.Maize protein doesn't contain lysine and tryptophane. Other than that maize is rich in carbohydrates (75%) and a little amount of fats (5%).

Prestained proteins are proteins that are already stained permanently so they are visible while running the gel. This technique makes pre-stained protein ladder, that are useful to track the proteins running on the SDS-PAGE gels. In addition the marks or protein ladder can be transferred to blot membrane by western blotting.

Proteins are polymer of amino acids. They contain both amino (-NH2) and carboxylic group (-COOH) as their main functional groups.With this the side chains specific for amino acids will attach and form poly peptides during protein synthesis.
