How does the end replication problem and telomerase affect aging in humans?
Telomerase ends become shorter as humans age. This happens in part because of the process known as the end replication problem, whereby strands of DNA become uneven over time.
The principal problem with inserting an unmodified mammalian gene into the bacterial chromosome and then getting that gene expressed is that?
bacteria cannot remove eukaryotic introns; bacterial dna does not contain introns like eukaryotic genes do so they had to be removed before being added to the plasmid.
Watson and Crick knew that the triple helix model of DNA that Linus Pauling had proposed was incorrect What evidence did they have for such a conclusion?
The problem of replication could not be worked out in triple helix.
What problem does chromosome number of various organisms present to evolutionists?
Evolutionists say that the smaller the animal the smaller the number of chromosomes.
What is an end replication problem?
The two strands of a DNA molecule are antiparallel to one another (the backbone of one strand runs from 5'-3' while the complimentary strand runs 3'-5'). Unfortunately, DNA polymerase, the enzyme responsible for replicating DNA, can only make DNA in a 5'-3' direction (and read DNA in the 3'-5' direction). Also, it needs a "primer" to give it a place to bind and start replication. So this creates a problem when synthesizing the 3'-5' stand because your enzyme will only synthesize 5'-3'. During replication this is solved by synthesizing small pieces of DNA ahead of the replication fork on the 5'-3' mother strand. Thus we have one daughter strand which is synthesized as a continuous piece of DNA (called the leading strand) and one daughter strand which is synthesized in small, discontinuous pieces (called the lagging strand). However, at the extreme end of the DNA, we run into another problem. The leading stand can be made to the very end, but the lagging strand cannot because you need the RNA primer upstream to begin each piece of the lagging strand DNA but at the end of the DNA there is nothing for this piece to attach to. Thus, the last section of the lagging strand cannot be synthesized and after several rounds of DNA replication, the DNA molecule gets smaller and smaller. This is "the end of replication problem" and it is solved by putting a DNA cap on the ends of DNA called a telomere which does not code for any protein, thus when this information is lost it does not have severe consequences for the cell.
How do eukaryotic organisms solve the problem of time constraints on replication of DNA?
The replication begins at origins along the DNA.
How are telomeres important for preserving eukaryotic genes?
Telomeres solve the end replication problem by extending the 3' end of the chromosome. Without them, the 3' end can't be replicated since replication is 5' to 3'.
What is the theoretical limit on the number of constraints on a linear programming problem?
There is no limit.
What is non linear programming problem?
It is a programming problem in which the objective function is to be optimised subject to a set of constraints. At least one of the constraints or the objective functions must be non-linear in at least one of the variables.
What is the main problem faced by small business?
financial constraints and lack of expansion
To solve a linear programming problem with thousands of variables and constraints?
a mainframe computer is required
How many constraints should be taken in optimal placement of capacitor problem for voltage improvement using Particle swarm optimization?
Four constraints should be taken in optimal placement of capacitor problem for voltage improvement using the Particle Swarm Optimization.
How does the end replication problem and telomerase affect aging in humans?
Telomerase ends become shorter as humans age. This happens in part because of the process known as the end replication problem, whereby strands of DNA become uneven over time.
How does the eukaryotic cell overcome the problem of its large size?
compartmentalizing cellular functions into various organelles
What are IP constraints in computer?
This could be due to your account not being the administrator . Some filters or firewalls on your computer causing this message You ISP having some IP constraints on your computer when it access the internet . Problem due to spyware or a program you newly installed.
What is the minimum number of constraints a linear programming problem can have?
One. To be a (non-trivial) linear programming problem both the objective function and the constraints must be linear. If there were no constraints then the objective function could be made arbitrarily large or arbitrarily small. (Think of a line in two-space.) By adding one constraint the objective function's value can be limited to a finite value.
Is the research problem feasible?
It depends on factors such as available resources, time constraints, and feasibility of data collection methods. Conducting a pilot study or literature review can help determine the feasibility of the research problem.
