In the question in regard to the ouchterlony test if there is an unknown antigen containing a swine serum album, the number of precipitin line that will form is one which is the answer. It relies in between the wells of the antibodies for the bovine albumin and the wells of the bovine albumin.
Cell interprets a genetic code by reading and interpreting each codon which corresponds to a single amino acid. each three letter "word" in mRNA is a codon. ... Protein synthesis creates proteins from amino acids. DNA replication creates a new DNA molecule from an existing one
The first stage of gene expression is the transcription step, ie the passage from ADn to mRNA, the RNA polymerase will read DNA (the TAC sequence) and will synthesize a complementary strand (AUG) in the form of mRNA (which will then undergo mRNA processing).
The second stage of gene expression is the translation of mRNA into protein: the AUG sequence of mRNA (supposed to be the start codon) is translated to the amino acid, methionine, via the ribosome and tRNA. The ribisome will read adjacent codons to form the polypeptide (several amino acids bonded together by peptide bonds).
The
molecules which move large molecules into and out of the cell are known as
membrane transport proteins-transporters.
<span>Their
function is to move all the molecules that are not capable to pass via passive
diffusion. So, transporters are involved in the movement of ions, small
molecules, or macromolecules, such as another protein, across a membrane.
Transporters are integral transmembrane proteins and can be categorized as channels
or carriers. These proteins assist in the movement of molecules by facilitated
diffusion or active transport.</span>
Answer:
B
Explanation:
Many organs such as stomach, teeth, are some things that make up the digestive system.
remember: organelles -> cells -> tissue -> organ -> organ system -> organism.
