(18 cards)
Chromosomes are made of blank and blank 
Proteins and DNA 
An organisms blank are encoded in segments of its chromosomes called blank 
Traits, jeans 
A DNA molecule is shaped like a twisted ladder a shape that is called a 
Double helix 
The genetic units called blank are made of sugar and blink group and a blank
Base
Nucleotides phosphate, nitrogen 
The process by which a new copy of DNA molecule is created is called… 
Replication 
Three kinds of blank molecules carry out genetic instructions for the production of proteins 
RNA
The process involves two main steps called blank and blank
Translation and transcription 
In the second of those steps units called blank are linked together 
Amino acids 
A change in a gene sequence of nucleotides is called 
Mutation 
A change in jeans, sequence of nucleotides can lead to a blank, such as CYSTIC FIBROSIS
