Answer:
On the basis of the phenomenon of the degeneracy of codons, the coding of single amino acid can take place by various codons like four different codons, that is, CCC, CCU, CCG and CCA can code for single amino acid proline.
In case, if there is a mutation in DNA, due to which CCA get transformed to CCG, even in such case coding for the same amino acid proline will take place. Hence, one can conclude that at the level of DNA mutation is taking place, however, the same is not getting witnessed in a protein, and that is why such kind of mutations are termed as silent mutation.
Neither the peptide hormones or the metabotropic neurotransmitters such as the catecholamines, can enter their target cells. They bind to surface receptors, which then activate second-messenger systems in the cell. Peptides hormones are the hormones that consist of amino acids; they can be among the intracellular signalling peptides and proteins, and can include insect hormones, gastrointestinal hormones and thyroid hormones, but their actions are not limited to individual cells and they can act systemically.
False.
Type A has A antigen and B antibody
Type B has B antigen and A antibody
Type AB (aka universal receiver) has both A and B antigen and NO antibodies
Type O (aka universal donor) has NO antigens and has A and B antibodies
