B) Polymerases can only synthesize in the 5' to 3' direction
C) There are only enough dNTP's to support quick replication on one strand, so the other strand lags behind it
D) It is necessary to "slow down" one of the strands so that replication does not occur before cells have a chance to grow
Answer:
B) Polymerases can only synthesize in the 5' to 3' direction
Explanation:
The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.
Answer:
The Hertzsprung-Russell Diagram is a graphical tool that astronomers use to classify stars according to their luminosity, spectral type, color, temperature and evolutionary stage. Stars in the stable phase of hydrogen burning lie along the Main Sequence according to their mass.
Explanation:
Answer:
1) C. Blood pressure cuff, towels, bitten cookies
2) C. Vector
Explanation:
1) C. Fomities are things that tend to carry infections. Here C is the most plausible answer
2) C. Vector. You often hear this when we talk about diseases that can spread like when mosquitoes spread disease, they act as vector
Fomites are non-living objects that can carry and transmit disease. In your question, the correct answer for fomites would be option C. For the second question, an insect transmitting a disease agent is known as a vector. Option c is the correct answer.
The term fomites refers to inanimate objects that, when contaminated with or exposed to infectious agents (such as bacteria, viruses, fungi), can transfer disease to a new host. Option A. Door handle, soap dispenser, a dog infected with rabies virus is partly correct because while door handles and soap dispensers can be fomites, a dog cannot be as it is a living organism. Similarly, option B. Pencils, a mosquito, unwashed iceberg salad partly fits the definition, but again, a mosquito (a living organism) can't be a fomite, it acts as a vector. Finally, option C. Blood pressure cuff, towels, bitten cookies are all non-living objects and thus can be considered as fomites. This means the answer to your first question isn't D. All choices are correct, but rather it's C. Blood pressure cuff, towels, bitten cookies.
In your second question, an insect that transmits a causative agent from an infected organism to an uninfected one is called a vector. So, the answer is C. Vector.
