Answer:
yes sure of it
Explanation:
Proteins are made up of amino acids that join together to form long chains. You can think of a protein as a string of beads in which each bead is an amino acid Antibodies are proteins in your blood that help protect your body from harmful invaders like bacteria and viruses. ... Without these antibodies,bacteria and viruses would be free to multiply and overwhelm your body with the disease they cause
Peptide bonds connect amino acids.
Please correct me if I'm wrong!!! I'd be happy to fix it!! :)
Answer: A protein domain is a region of the protein's polypeptide chain that is self-stabilizing and that folds
independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains.
One domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions.
In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length.
The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium binding EF-hand domain of calmodulin.
Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins.
Mature DNA cells do NOT contain DNA.
Answer:
option D
Explanation:
Negative feedback is a mechanism in which function of a cell or an organ is decreased. It lessened the output of a system and maintain system function which is known as homeostasis. It is a regulatory mechanism of normal physiology. Some of examples are
blood sugar level regulation, regulation of blood pressure, thermoregulation and many more.
