Molecular structure of chromosomes and transposable elements - Organization of functional sites along eukaryotic chromosomes
6 important questions on Molecular structure of chromosomes and transposable elements - Organization of functional sites along eukaryotic chromosomes
What is the shape of eukaryotic chromosomes?
How many genes does a single chromosome have?
How many bp does a eukaryotic gene have?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Why are protein-encoding genes in more complex eukaryotic organisms much longer than in less complex organisms?
What are the specialized regions at the end of the eukaryotic chromosomes called?
What are the functions of the telomeres?
- Prevent chromosome shortening:
- Telomeres protect chromosomes from digestion by exonucleases that recognize the end of DNA;
- An unusual form of DNA replication occurs at this site to prevent the chromosomes from being shortened with each round of DNA replication.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
