Flashcards in Chapter 1.4 DNA and the production of proteins Deck (14):
Chromosomes are made up of regions called
DNA is a complex substance that forms
the genes of all living organisms.
DNA carries the genetic information, which is information for making
A single DNA molecule is a
Each strand of DNA is a chain carrying molecules called
There are four different types of bases and they are
Adenine, Thymine, Guanine and Cytosine
The strands of the DNA helix are held by
bonds between bases on each strand
The bases bond together to form
complementary base pairs.
Base A only pairs with
Base G only pairs with
The sequence of bases A,T,G and C make up the
The base sequence of a specific gene determines the
amino acid sequence in the specific protein to be assembled.
Proteins are assembled at
ribosomes in the cell cytoplasm
