Question

1. what determines the sequence of amino acids in a protein? * 2 points

a.the sequence of nucleotides in dna
b.the shape of the ribosome
c.the type of trna present
d.the number of mitochondria in the cell

1. what is the primary function of muscle cells? * 2 points

a.to transmit electrical signals
b.to contract and produce movement
c.to carry oxygen
d.to protect the body from infection

Explanation:

For question 5, the sequence of nucleotides in DNA is transcribed into mRNA, and then the mRNA sequence determines the sequence of amino - acids in a protein during translation. For question 6, muscle cells are specialized for contraction, which leads to movement of body parts or internal organs.

Answer:

1. A. The sequence of nucleotides in DNA
2. B. To contract and produce movement
