Termination of DNA synthesis in E. coli and humans differ significantly because of the genomic structures involved, namely a cir

cular genome in bacteria and linear chromosomes in humans. Briefly describe structure and function of the ONE key E. coli protein and the ONE key human protein that are each needed for high fidelity termination of DNA replication.

Answer:

Main protein in ending high fidelity in E. Coli is the Tus protein that binds to Ter sequences in order to prevent replication forks from passing through the end region. In the Ter sequences, the Tus protein blocks replication by establishing a close association with a particular G-C base pair.

The main protein in human cells is telomerase, which contains an RNA primer and is required to extend the synthesis of lagging strands in linear chromosomal telomeres.

Assuming this is for an EMT-B course, you would call your medical director for direction and give oral glucose if they are alert enough to control their own airway.

If this is for a Paramedic course, you will start an IV and administer D50 at a slow push.

What is a spore that develops by mitosis.
o-na [289]

Answer:

<em>The correct option is A. mitospore</em>

Explanation:

A mitospore can be described as a haploid or diploid spore. Generally, a spore is formed by meiosis but under certain conditions it can form by the process of mitosis and is known as mitospore.

When spores are formed by sexual methods, meiosis occurs. When they are formed by asexual methods, mitosis occurs. Asexually, there are different ways by which mitospores form by mitosis.

Katena32 [7]

Answer:

only sympathetic fibers can regenerate accurately

Explanation:

Neuroregeneration is a complex biological process associated with the regrowth and/or repair of nervous tissues. This process depends on the type of nerve tissue and how seriously the nerve was injured. The autonomic nervous system, also known as the autonomic nervous system (ANS), is part of the peripheral nervous system (PNS) that is responsible for regulating involuntary physiological processes. The PNS contains two basic divisions: sympathetic and parasympathetic. The sympathetic fibers innervate tissues in nearly all the organ systems and they are responsible for regulating homeostatic processes (e.g., heart rate). The sympathetic nervous system is formed by nerves from the thoracic and lumbar segments of the spinal cord. These autonomic nerves can regenerate after injury in order to reinnervate target tissues (e.g., after chronic cardiac ischemia).

Which best describes the offspring of protists?
Hunter-Best [27]

Options found elsewhere:

-always genetically identical to one parent

-always genetically identical to both parents

-never genetically identical to one parent

-sometimes genetically different than both parents

Answer:

-sometimes genetically different than both parents

Explanation:

Protists are eukaryotes that cannot be classed as animals, plants, or fungi. They are quite diverse. Examples include amoeba, plasmodium, and slime mould.

Because they are so diverse, protists also have very different modes of reproduction. Some protists undergo asexual reproduction, where they simply make a copy of themselves without a mate. Others undergo sexual reproduction.

Therefore, the only option that can be correct is "-sometimes genetically different than both parents" .

If they were always genetically identical to one parent or both parents, that would mean that sexual reproduction could not be possible. If they were never genetically identical to one parent, that would mean that asexual reproduction could not be taking place.
