2) pairs of chromosomes blending together
3) Watson-Crick pairing of the bases-the correct nitrogen bases are added to each side of the unzipped DNA
4) long strands of amino acids woven together to create proteins

Answer 10

3) Watson-Crick pairings of the bases -the correct nitrogen bases are added to each side of the unzipped DNA

Question 11

mRNA ….

1) is woven together with proteins to create the ribosome of the cell.
2) carries amino acids to the ribosome for protein synthesis
3) stands for “maternal ribonucleic acid”
4) contains the code or message that it takes to the ribosome for how to build the protein.

Answer 11

4) contains the code or message…..

Question 12

tRNA….

1) carries amino acids to be ribosome for protein synthesis.
2) contains the code or message that it takes to the ribosome how to build the protein
3) is woven together with proteins to create the ribosome of the cell.
4) stands for “terrific ribonucleic acid”

Answer 12

1) carries amino acids to the ribosome for protein synthesis
tRNA- remember the t stands for transfer or carries
