The smaller chunks of DNA are called genes.
Humans have 46 chromosomes.
The author compares the instructions in DNA to a recipe book.
The author compares alleles to different versions of a recipe.
We get 23 chromosomes from each parent.
Siblings aren't exactly the same because they may inherit different combinations of genes from their parents.
When a cell reads a gene's instruction, it is called transcription.
The important group of helpers that interpret a gene's instructions are proteins.
The process of making RNA from DNA is called transcription and it occurs in the nucleus.
The second step is called translation.
Translation converts the instructions in RNA into a protein.
Humans have 20 amino acids.
Some functions of proteins mentioned in the article are acting as enzymes, transporters, and structural components.
tRNA helps translate the instructions in RNA into a protein.
The other helper molecule mentioned in the article is called RNA polymerase.
Splicing variations and gene switches result in different forms of proteins being produced.
Only a small percentage of DNA gets translated into proteins.
The estimate of the portion of DNA that controls gene expression is around 1-2%.
The author compares controlling gene expression to turning on or off certain switches in a house.
The smaller chunks of DNA are called nucleotides.
Humans have 46 chromosomes (23 pairs).
The author compares the instructions in DNA to a blueprint.
The author compares alleles to different versions of a gene.
We get 23 chromosomes from each parent.
Siblings are not exactly the same because they inherit different combinations of genes from their parents.
When a cell reads a gene's instruction, it is called transcription.
The important group of helpers that interpret a gene's instructions are proteins.
The process of making RNA from DNA is called transcription, and it occurs in the nucleus of the cell.
The second step is called translation.
Translation converts the instructions in RNA into a sequence of amino acids, forming a protein.
Humans have 20 amino acids.
Some functions of proteins mentioned in the article include acting as enzymes, providing structure to cells and tissues, and assisting in cell signaling.
tRNA (transfer RNA) carries the amino acids to the ribosome during translation.
The other helper molecule mentioned in the article is mRNA (messenger RNA).
Splicing variations and gene switches can result in different forms or levels of gene expression.
Only a small percentage of DNA (about 2%) gets translated into proteins.
The estimate of the portion of DNA that controls gene expression is around 1-2%.
The author compares controlling gene expression to turning certain genes on or off, like a light switch.
