Arrange the symbols to form a DNA molecule.
Julli [10]

The right answers are mentioned in the picture.

A base pair (bp) is the pairing of two nucleobases located on two complementary strands of DNA or RNA. This pairing is carried out by hydrogen bridges. There are four types of nucleic bases: A-T-C-G, these letters for Adenine, Thymine, Cytosine, and Guanine. A with T and C with G.

It is also necessary to take into account the antiparallel character of the DNA strands. If a strand is in the 5 '3' direction, its complete strand is in the 3 '5' direction.

If a homozygous black bull is mated with a homozygous white cow and the calf is gray, this would be an example of ________. howe
I am Lyosha [343]

The first statement above is an example of incomplete dominance. If the calf has black and white spots then that’s an example of codominance.

 

Incomplete dominance is a form of transitional inheritance in which one allele for an explicit trait is not entirely expressed over its paired allele. This effects in a third phenotype in which the expressed physical trait is a mixture of the phenotypes of both alleles.

 

Codominance<span> is a form of dominance by which the alleles of a gene pair in a heterozygote are wholly expressed. This effects in offspring with a phenotype that is neither dominant or recessive. A usual example showing this type of dominance is the ABO blood group system.</span>
