Answer:

D. Nucleic acids attach to the bases in the DNA.

Explanation:

Transcription begins when an enzyme called RNA  polymerase  is added to the DNA template and begins a new chain a new chain to produce complementary RNA.

During the RNA synthesis transcription takes place, then the cap and tail is added and then splicing occurs.

RNA polymerase moves from the 3' end to the template strand creating the RNA-DNA double helix or similar the base sequences. This makes a chain with each sugar by the set of bonds called phosphodiaster linkage. Then, the enzyme unwind the DNA and begins the synthesis of RNA.

Therefore, D. Nucleic acids attach to the bases in the DNA.

garik1379 [7]

Answer:

Both A and B

Explanation:

True breed is a breed that is 100% identical with the parent, the traits inherited from that parents are 100% controlled by same allele of a gene hence they are exact copy.

A single gene can have several alleles, it is the allele that combines together that determines what is seen or expressed.

Allele for blue colour is dominant over allele for red color and that is what led to the phenotypic appearance of the offspring which is blue and the red color is masked. Also, because they are true breeds it means the genotype have the same allele e.g. AA
