seperate the meaning.
DNA – double-stranded molecule that carries genetic information DNA polymerase – an enzyme that plays a critical role in placing nucleotides in the correct order inheritable genetic variations – changes in genetic material that can be passed to offspring mutation – a change in a DNA sequence replication – the copying of genetic material viable errors – changes that can be passed to living offspring Cell theory – all organisms are made of cells and they come from pre-existing cells Substitution mutation – a nucleotide base is replaced with the wrong corresponding pair Insertion mutation – add extra base pairs to the DNA sequence making it longer than it should be to code specific proteins Frameshift mutation – adding or removing base pairs so that the DNA sequence can no longer be put into exact triplets Point deletion – when one base is deleted in the DNA sequence which can lead to incorrect protein synthesis Epigenetic changes – DNA modifications that do not affect the sequence but the expression of certain genes Epigenome – made of compounds and proteins that attach to DNA and can affect which genes are turned “on” or “off” in the production of certain proteins Methylation – the attaching of methyl groups (made of one carbon and three hydrogen) to DNA to regulate gene expression Under-methylation – having too few methyl groups to help regulate gene expression that can lead to neurological symptoms and disorders Over-methylation – having too many methyl groups trying to regulate gene expression that can lead to neurological symptoms and disorders
DNA - double-stranded molecule that carries genetic information
DNA polymerase - an enzyme that plays a critical role in placing nucleotides in the correct order
Inheritable genetic variations - changes in genetic material that can be passed to offspring
Mutation - a change in a DNA sequence
Replication - the copying of genetic material
Viable errors - changes that can be passed to living offspring
Cell theory - all organisms are made of cells and they come from pre-existing cells
Substitution mutation - a nucleotide base is replaced with the wrong corresponding pair
Insertion mutation - add extra base pairs to the DNA sequence making it longer than it should be to code specific proteins
Frameshift mutation - adding or removing base pairs so that the DNA sequence can no longer be put into exact triplets
Point deletion - when one base is deleted in the DNA sequence which can lead to incorrect protein synthesis
Epigenetic changes - DNA modifications that do not affect the sequence but the expression of certain genes
Epigenome - made of compounds and proteins that attach to DNA and can affect which genes are turned "on" or "off" in the production of certain proteins
Methylation - the attaching of methyl groups (made of one carbon and three hydrogen) to DNA to regulate gene expression
Under-methylation - having too few methyl groups to help regulate gene expression that can lead to neurological symptoms and disorders
Over-methylation - having too many methyl groups trying to regulate gene expression that can lead to neurological symptoms and disorders
