Answer:
9 amino acids
Explanation:
A segment of a gene that has 27 nucleotides will code for<u> 9 amino acids.</u>
<em>Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.</em>
number of amino acids = number of nucleotides/3
27/3 = 9 codons/amino acids
Enzymes reduce the activation energy allowing chemical reactions to occur in living things.
Answer:
The correct options are MACROPHAGES AND NEUTROPHILSE.
Explanation:
Majority of the white blood cells in humans are specialized phagocytic cells, examples of these are macrophages, neutrophilse, monoctyes, mast cells and dendritic cells. The major functions of phagocytic cells is to protect the human body from disease pathogens. They do this by ingesting foreign bodies that are found in the body. Macrophages and neutrophilse are the major phagocytic cells in the body, they are the principal effector of non-specific host defense and inflammation.
