- This are the structures formed by the DNA and proteins that house multiple genes in the cell nucleus.
- This are segments of DNA that contains instructions for protein synthesis and determine hereditary traits.
- What Century is it when the scientist conducted experiments with peas thet revealed patterns of inheritance. He did not know that these patterns were related to DNA
- What Century is it when it was discoverd that the DNA is the molecule that carries genetic information. It revolutionized genetics and biology.
- What Century is this when generic engineering and DNA sequencing is possible. This enable men to have adept study of genes and their influence on inheritance.
- This is the biological process through which organisms transmit genetic traits such as physical traits and behavior patterns to their offspring by TRANSFERRING genetic material which includes DNA or RNA in the case of various organism.
- Inheritance involves the transmission of genetic information from parents to offspring, determining characteristics in the progeny.
- Through inheritance, biological traits are perpetuated and diversified in all species on Earth.
- Inheritance is essential for the continuity and adaptation of species over generations.
- What makes us different or similar?
- An essential molecule found in the nucleus of living organism's cells. It can be compare to a book of genetic instructions that determines how an organism develops and functions.
- During the mid 1980s and early 1990s, scientists explored trait inheritance in organisms through experiments with peas and flies. However they were not able to get to complete understanding of control mechanics.
- Scientists discovered the double-helix structure of DNA using data from other scientists. This revealed how DNA stores genetic information.
- What is the significance of discovering DNA structure?
- What is a polymer?
- From a chemical perspective, DNA is a polymer of what?
- DNA is a double helix structure it resembles what?
- DNA consists of four nitrogenous bases
- Adenine or A pairs with?
- C or Cytosine pairs with
- Nucleotides are the basic unit of DNA it is composed of?
- Basic functions of DNA
- DNA stores the genetic information that determines the characteristics and functions of an organism.
- DNA can make exact copies of itself, which is essential for cell division and growth.
- DNA is transcribed into RNA and then translated into proteins, which control cellular activities.
- DNA is inherited from generation to generation and is responsible for passing traits from parents to offspring.
- The two DNA strands unwind and separate, breaking the hydrogen bonds between complementary bases ( A-T, C-G )
- Free nucleotides pair with the exposed bases on each strand , following the rules of complementary.
- Two new DNA strands are formed , one for each original strand, using the paired nucleotides as building blocks.
- The results is the formation of two DNA molecules, identical to the original, ready for cell division
- Daughter cell of mitosis
- Daughter cell of meosis
- A molecule that forms genes
- Multiple genes, what does it create?
