DNA and the production of proteins

Cards (17)

    • Chromosomes are made of DNA. 
    • DNA is found in the nucleus and carries the genetic instructions to make proteins
  • a gene is a short strand of DNA that codes for a specific protein.
  • a gene is small part of the DNA strand
    the DNA is found in the chromosome
    the chromosome is found in the nucleus of the cell
  • DNA is a double stranded molecule
  • DNA is made up of 4 bases - Adenine (A), Cytosine (C), Guanine (G) and Thymine (T)
  • adenine pairs with thymine
  • cytosine pairs with guanine
  • DNA strands are held together with complementary base pairings - meaning each base can only pair with one other base
  • DNA is unique to each person because it is made up of different combinations of the four bases.
  • The DNA sequence determines what proteins will be produced by the cell, which determine its characteristics.
  • what is a section of DNA called ?

    Gene
  • what do genes code for?

    proteins
  • proteins determine the characteristics of an organism
  • where is the code to make proteins stored?

    in bases on DNA in the nucleus
  • MRNA carries a complementary copy of DNA from the nucleus to the ribosome
  • in the ribosome proteins are made from amino acids
  • how proteins are made
    a complementary copy of the DNA strand is made
    the mRNA carries a copy to the ribosome
    the order of the DNA bases then determine the order of the amino acids
    the order of the amino acids then determines the shape of the protein giving it its function
