Answer:

Explanation:During fertilization the embryo receives half of its genetic information from both parents. If one parent is a carrier or sickle cell their genes would be Aa little a being the recessive gene. When mixed with the other parents gene who does not have sickle cell their genes would be AA. When you make a pun net square the results would be AA,AA,Aa,and Aa. Therefore the offspring would have a 50% chance of being a carrier of sickle cell but not having the actual disease

barxatty [35]
<span>Proteins are large biological molecules consisting of one or more chains of amino acids.  Proteins differ from one another primarily in their sequence of amino acids, which is decided by the nucleotide sequence of their make-up, and which usually results in folding of the protein into a three-dimensional structure that determines its job. 
    </span><span>Nucleic acids are linear polymers (chains) of nucleotides. Each nucleotide consists of three things: a purine , nitrogenous base a pentose sugar, and a phosphate group.  
    </span><span>
 Basically Proteins are chains of amino acids, nucleic acids are chains of nucleosides (base+sugar+phosphate), and the sequence of nucleic acid results in the specific sequence of amino acids in the protein, finnally determining its shape and function. </span>
