Answer the following statements true (T) or false (F)
1. In epistasis, two opposing genes are expressed equally.
2. In eukaryotes, DNA wraps around proteins known as histones inside the nucleus of the cell.
3. Telomeres grow in length with each round of DNA replication.
4. Prokaryotic mRNA is more stable than eukaryotic mRNA because its maturation takes fewer steps.
5. Each domain of organisms has its own unique codons to code for protein synthesis.
1. False
This statement is false. In epistasis, one gene masks the expression of another.
2. False
This statement is false. In prokaryotes, DNA wraps around proteins known as histones inside the nucleus of the cell.
3. False
This statement is false. Telomeres get shorter in length with each round of DNA replication.
4. False
This statement is false. Prokaryotic mRNA is less stable than eukaryotic mRNA because its maturation takes fewer steps.
5. False
This statement is false. Each domain of organisms uses the same codons for protein synthesis, such as start codons and stop codons.
