codominance

Answer 9

Both traits are expressed on different parts of the organism, black chicken with white spots

DNA polymerase unzips the DNA and mRNA uses that as a template to create a single strand.

Question 11

translation

Answer 11

The tRNA carries amino acids and matches it to the anticodon it reads from mRNA codons in the cytoplasm

Answer 14

Frame shift mutations

Question 15

Answer 15

No, it only gets passed down if it occurs in a gamete

Question 16
