Exam 5: Cell Growth and Reproduction

Match each phase of mitosis with its corresponding description. -chromosomes elongate into chromatin form and spindle fibers disappear

Describe the structure of a DNA molecule.What is the importance of the "triplet?"

The anticodon on the tRNA molecule has exactly the same nucleotide sequence as the DNA code that formed that part of the mRNA molecule except that uracil would replace thymine.

Match each of the terms related to protein synthesis with its corresponding statement or definition. -can inhibit the process of protein synthesis

Match each of the terms related to protein synthesis with its corresponding statement or definition. -type of RNA that has an anticodon and binds to a specific amino acid

Match the following terms with their definition or description. -This is the term used to describe the normal number of chromosomes in most body cells.

Genes determine polypeptide structure,which determines the structure of enzymes and structural proteins,which determine the cell's functions and structure.

A human gene is made up of about 250 DNA nucleotides.

Atrophy and hypertrophy occurs most often in fat cells as the body stores or uses fat.

If the original DNA code was ACG,the tRNA that would transfer the correct amino acid would have which sequence of nucleotides?

If the original DNA code was CAA,the transfer RNA for that strand of DNA would be CAA.
