Traits show up in the offspring
Gene expression:
The process by which DNA directs the synthesis of proteins
Two stages in the expression of genes:
Transcription and Translation
Proteins are made of building blocks called…
Amino acids

4
The three nucleotides in sequence must specify each…
Amino acids
Codon:
A triplet of nucleotides
Each codon calls for a specific:
Amino acid
When many amino acids are linked together a…

3
Does a gene build a protein directly?
No
The bridge between DNA and protein synthesis is…
RNA
Strand difference between DNA and RNA:
RNA is a single strand
DNA is a double strand
Sugar difference between DNA and RNA:
Sugar in RNA is ribose
Sugar in DNA is deoxyribose
Nitrogen base pairs difference between DNA and RNA:
RNA has uracil
DNA has adenine
