Information is encoded in DNA, then copied onto RNA during transcription. Then, ribosomes convert the information carried in RNA into a protein, in the process of translation. Also, A and D could be ruled out because DNA and RNA are solely involved with proteins, but polysacchariades are chains of sugars.
The proteins that help defend the body against bacteria, toxins, and allergens are called antibodies. The antibody<span> (Ab) protein is also known as an immunoglobulin (Ig). </span>These<span> large Y-shaped proteins are</span><span> produced by the immune system in order to prevent the body in response to the presence of a foreign substance. The foreign substance is called antigen. </span>
Marfan syndrome is a genetic problem which affects the connective tissue in the body. The trait for this disease is autosomal dominant which means even one abnormal copy of this gene in the offspring or individual is sufficient to cause this syndrome.
Let S is the allele that is dominant for this syndrome and s is recessive. So if a cross between homozygous dominant(SS) and heterozygous individual (Ss) occurs than all the offspring would have this syndrome.
S s
S SS Ss
S SS Ss
Therefore all 4 offspring would have at least one dominant allele which is sufficient to cause this syndrome. So the phenotype ratio would be 4:0.
