Sickle Cell Anemia is caused by a point mutation known as a substitution. Show what would occur if the first T (“thymine”) DNA base in the portion shown above experienced a mutation with a substitution of A (“adenine”). Sickle Cell Hemoglobin: Portion of mutated hemoglobin DNA: mRNA: Amino Acids:

the answer is otpion c) understanding

he wants to be heard one more time. he wants to be understood. he needs the truth one more time.

human-caused climate hope this

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.
