Question

What is wrong with this?

1. Changes (mutations) in the sequence of DNA over evolutionary time are called transcription factors.
2. Specialized proteins that can influence gene expression by binding to DNA in one region of the protein and in a second region are able to bind small-molecular-weight ligands are known as single-nucleotide polymorphisms.  
3. When a change in a single nucleotide occurs frequently in a population, it is referred to as a transcription factor.
4. The subdiscipline of nutritional genomics concerned with detecting gene variants within an individual, discovering their effect on function, and identifying which environmental factors interact with those variants to trigger dysfunction or disease is known as epigenetics.

Answer 1

1. Changes (mutations) in the sequence of DNA over evolutionary time are called evolution.

2. Specialized proteins that can influence gene expression by binding to DNA in one region of the protein and in a second region are able to bind small-molecular-weight ligands are known as Transcription factor. because transcription factors are proteins which binds to the promoter region which lies upstream of the trancription start point and therefore regulate the expression of that particular gene.

3. When a change in a single nucleotide occurs frequently in a population, it is referred to as single-nucleotide polymorphisms. It is because, change with different nucleotide results in differences in the sequence at single locus whcih gives

4. The subdiscipline of nutritional genomics concerned with detecting gene variants within an individual, discovering their effect on function, and identifying which environmental factors interact with those variants to trigger dysfunction or disease is known as epigenetics.​​​​​​​
