How proteins are made​
Ira Lisetskai [31]

Proteins are an important class of molecules that carry out most of the work inside cells. The building blocks of proteins are smaller organic molecules called amino acids. Most organisms, including humans, use only 20 different amino acids to assemble the vast multitude of proteins needed to build and run a cell.

To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.  

After the polypeptide chain is synthesized, it will sometimes undergo additional processing. For example, some proteins will have certain amino acids removed. Or extra molecules such as sugars or phosphates may be attached to some of the amino acids in a protein.

A student wants to cross parent mice to produce offspring with black fur and offspring
topjm [15]

Answer:

Bb and Bb

Explanation:

This is the only combination of the four that will produce both mice with black fur and mice with white fur. Option A will only give black fur, option B will only give white fur, and option C will only give black fur since parent 1 will only give the dominant B allele to the offspring. With Bb and Bb, the genotypes of the resulting offspring could be BB, Bb (which will result in black fur) or bb (which will result in white fur).
