What is Methylation? Ans: addition of methyl groups (CH3) to specific DNA nucleotides What performs methylation? Ans: DNA methyltransferases, add primarily to Cytosine bases What bases are primarily methylated? Ans: Cytosine - located in CpG dinucleotides What is a CpG dinucleotide? Ans: side by side Cytosine and Guanine nucleotides in same DNA strand What part of DNA is mostly methylated? Ans: In eukaryotic genomes, most methylated DNA is found in transposable elements and non-coding...

Homeotic genes contain a homeobox sequence that is highly conserved among very diverse species. The homeobox is the code for that domain of a protein that binds to DNA in a regulatory developmental process. Therefore, you would expect that _____. - ️️homeotic genes are selectively expressed as an organism develops A current view of how the human and chimpanzee can share most of their nucleotide sequence yet exhibit significant phenotypic differences is that many of the most important sequen...

In which location in the genome are transposable elements least likely to experience strong selection? a noncoding area of the genome that experiences little recombination There are 1,200 functional olfactory receptor genes in the mouse genome and only 550 in the human genome. Which of the following is the possible reason? genes that are rarely used can degenerate because of reduced selective pressure Mutations at the third position of the codon are more likely to _____ than mutations at the f...
