During dna replication, a primer attaches to a template strand of dna and begins a new strand. after the primer has attached, an enzyme extends the new strand of dna by adding nucleotides that correspond to the nucleotide sequences in the template strand. which enzyme is responsible for adding nucleotides to the growing dna molecule?

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
