a) 2:2 are likely to have smooth nose. 2:2 are likely to have wrinkled nose ( heterozygotes).
b) 2:2 are likely to have smooth nose. 2:2 are likely to have wrinkled nose.
c) 50% is the probability of having smooth-nosed offspring.
d) 50% is the probability of having two smooth-nosed offspring.
Answer:
1) A double Helix with complementary bases in the middle. The backbone is made of sugar and phosphates. The middle is bases
2) To hold the genetic info for the cell
3) To bring the genetic info from the nucleus to the ribosomes as DNA can't leave the nucleus
4) To bring amino acids to the ribosomes to help build a protein
5) A chain of amino acids held together by peptide bonds
6) Ribosomes
7) Because those are the bases that are complementary in DNA so they must be equal
8) It could lead to a mutation as it would cause the mRNA to code for a different amino acid and thus a different protein will be made
9) DNA is the blueprint for mRNA which will travel to the ribosomes and code for specific amino acids which will eventually build a protein
B, the independent variable because this is the one that is purposefully changed in an experiment to test the hypothesis.
