The linker histone H1 is involved in stabilizing the nucleosome structure by binding to the DNA between nucleosomes. However, DNA methylation is not a post-translational modification of histone proteins. DNA methylation involves the addition of a methyl group to a cytosine base in the DNA molecule and can affect gene expression and chromatin structure. Therefore, statement 1 is true, and statement 2 is false. Hence option 2 is the correct answer.
