Albumin is a protein that is secreted by liver cells and transported to the bloodstream. What factor most directly determines the amino acids that are combined to create albumin?

• The temperature of the cell when translation is taking place

• The number of chromosomes in a cell

• The sequence of nucleotides in DNA

• The amount of energy that is available in the cell

Answer explanation

albumin = a protein

DNA codes for proteins

sequence of nucleotides in DNA determines sequence of amino acids in a protein!

A scientist examined two populations of grasshopper species Atractomorpha lata. The scientist found that the population raised in higher temperatures had a higher frequency of brown coloration, while the population raised in lower temperatures had a higher frequency of green coloration.

Based on this information, which biological process is affected by temperature in A. lata?

• gene expression

• cell division

• ATP production

• metabolism

A simplified model of a biological process with two steps is shown.

Which explanation best describes the purpose of Step 1 in this process?

• to make an RNA copy of the DNA

• to make an exact replica of the DNA

• to transfer amino acids to the polypeptide chain

• To catalyze the reaction that bonds amino acids together

A simplified model of a biological process is shown.

What is the purpose of this process?

• to replicate the DNA of an organism before cell division

• to assemble nucleotides in an mRNA chain along a DNA template

• to synthesize amino acids used to unzip strands of DNA and copy the genetic code

• to translate the genetic code into a specific sequence of amino acids
