The correct answer is: gaps left at the 5' end of the lagging strand
Telomeres are repetitive regions at the very ends of chromosomes found in eukaryotic organisms. The “problem” with telomeres is that the DNA replication cannot be fully finished in each round which result in a slow, gradual shortening of the chromosome.
Gaps at the end of lagging strand are formed because lagging strand is synthesized via Okazaki fragments (small DNA fragments). So, when replication fork during replication reaches the end of the chromosome, a short stretch of DNA does not get covered by an Okazaki fragment and consequently remains uncopied in each round of replication, leaving a single-stranded overhang.
Telomerase is an enzyme that solves this problem by extending the telomeres of chromosomes.
Answer: 1. do honeyguides in different areas of the world have a similar symbiosis with humans?
2. how old are the birds when they learn to respond to the humans' calls?
3. could other birds in the region form a similar symbiosis with humans?
Explanation:
Equator area: closest to the sun and hot and humid due to the mass evaporation from the excess heat.
Mid equator/south pole: somewhat mild, colder, probably mid-humid, depending on which end of the midsection you're going for
South Pole: cold and dry. Cold because it's naturally far away from the sun (like the north pole) and dry because there isn't significant water evaporation here and any that may form crystallizes into snow and ice.
The ecosystem is very complex and simulations do not include all of the factors that may impact ecosystem processes.
