DNA

• What does DNA stand for?


  Deoxyribonucleic acid.
• What is the shape of a DNA molecule?


  A double helix.
• Where is DNA found in a cell?


  n the nucleus, within chromosomes.
• What is the role of the DNA?


  It contains the genetic information for building and maintaining an organism.
• What are the four bases in DNA?


  Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
• Which bases pair together in DNA?

  Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G).
• What type of bond holds complementary bases together?


  Hydrogen bonds.
• How many hydrogen bonds connect A-T and C-G?


  A-T has 2 hydrogen bonds; C-G has 3 hydrogen bonds.
• Gene


  small section of DNA that codes for a protein.
• Genome


  entire set of a gentic material in an organism.
• What forms the "sides" of the DNA double helix?

  The sugar-phosphate backbone.
• What connects the two strands of DNA?


  The nitrogenous base pairs.
• what is the genetic code?


  genetic code is the set of instuctions.
• what are proteins made up of?


  proteins are made up of chains of molecules called amino acids joined together.
• what does the order of bases in a protein determine?


  the sequence of amino acids in a protein.
• What is the shape of DNA?

  DNA has a double helix shape, meaning it consists of two strands twisted around each other.
• How are the two DNA strands held together?

  The strands are linked by complementary base pairs joined by weak hydrogen bonds.
• What are nucleotides?

  Nucleotides are the building blocks of DNA. Each nucleotide consists of:1️⃣ A sugar2️⃣ A phosphate group3️⃣ One of four bases (A, T, C, or G)
• What forms the backbone of the DNA structure?

  The sugar and phosphate groups form the backbone, while the bases pair in the middle.
• gene


  a gene is a segment of DNA that contains instructions for making proteins, which determine traits and functions in an organism
• genome

  A genome is the complete set of DNA in an organism, containing all the genetic information needed for that organism to grow, develop, and function.
• How are the two strands coiled to form a double helix?

  the strands are linked by a series of complementary base pairs joined together by weak hydrogen bonds
• What is DNA as a polymer made up of?

  DNA as a polymer is made up of nucleotides that consist of a sugar and phosphate group with one of the four different bases attached to the sugar
• DNA is a _______

  DNA is a polymer
