7D Nature vs nurture

As well as being influenced by genes and their proteins, phenotype is also influenced by the ___________. This is known as proportionate heritability.

Epigenetic factors can both ​​ (a)   (switch on) or ​ (b)   (switch off) the ​ (c)   of various ​ (d)   .

• activate
• deactivate
• expression
• genes

Label the following diagram showing the two processes involved in gene expression.

Which stage of gene expression is generally affected by epigenetic changes?

• Transcription

• Translation

• Both transcription and translation

The two main types of epigenetic changes are ​DNA ​ (a)   and histone ​ (b)   .

• methylation
• modificiation
• transpiration

Epigenetics plays an important role in allowing cells of an organism to function differently despite having the same DNA, known as cell _______________.

Epigenetic changes can be passed on to daughter cells during mitosis, which is known as being somatically:

• heritable

• transferrable

• changeable

• possible
