DNA is made up of (nucleotides / nitrogenous bases), joined by covalent bonds between the (adenine / guanine / thymine/ deoxyribose) of one monomer and the (phosphate group / nitrogenous base) of the next monomer. The DNA of all members of a species has (the same / a different) nitrogenous base composition. The percentage of (adenine (A) / guanine (G) / thymine (T) / cytosine (C)) always equals the percentage of thymine (T), and the percentage of (adenine (A) / guanine (G) / thymine (T) / cytosine (C)) equals the percentage of cytosine (C). It follows that if the percentage of adenine plus thymine equals 40%, then the percentage of guanine plus cytosine would equal (15% / 20% / 30% / 60%)​

Nhumans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? in humans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? a, b, ab, and o ab and o a, b, and o a and b
