What of the following checks dna for errors

Biology
1 answer:
HACTEHA [7]3 years ago
5 0

Answer:

A. DNA polymerase

Explanation:

DNA polymerases (I,II,III) proofread the DNA, which helps to catch errors. Errors can be fatal to expression, creating misformed proteins or unclear information, so this is necessary.

Fun facts - the coronavirus is a retrovirus, so it doesn't proofread. That makes it much harder to find a vaccine, because it can generate new strains by the very fact of not proofreading.

Since mature red blood cells do not contain a nucleus, more room is available for
geniusboy [140]

Answer:

The correct answer is : oxygen

Explanation:

  • Oxygen is carried in the blood by two means:
  1. About 2% of the oxygen is carried in the dissolved form in blood plasma and in the water present in the red blood cells (RBCs).
  2. Rest 98% of the oxygen is carried in bound form with the haemoglobin as oxy-haemoglobin inside the RBCs.
  • RBCs lack nucleus. This place is occupied by hemoglobin molecules that  binds to oxygen and form oxy-hemoglobin.
  • This increases the capacity of each RBC so that it can carry more oxygen to all the parts in the body.

Which of the following correctly lists functions of proteins? transporting substances, creating proteins, and fighting disease b
Sunny_sXe [5.5K]

Answer:

The correct answer is providing structure, regulating cell processes and creating movement.

Proteins are large molecules consisting of one or more polypeptide chains. They perform many important functions in the body such as:

  • Structural base: they are the building blocks of the cell.
  • Movement: They help in locomotion of a cell. For example, actin and myosin present in muscle cells.
  • Hormones: Many hormones are protein in nature and help in the control and coordination of the body. For example, insulin and growth hormones are protein in nature.
  • Enzymes: Most of the enzymes are protein in nature. Enzymes are biological catalysts which regulate the biochemical reactions taking place in an organism.
  • Defense: Antibodies are protein in nature.
  • Transport: Proteins form channels across the plasma membrane which facilitate the transport of molecules across the membrane.

In contrast, DNA acts as the genetic material which forms the blueprints of an organism as well as the bases of heredity. They are transcribed into different types of RNA which together synthesize the proteins.

Explain why the metric system and si are important​
Dovator [93]

Answer:
In simple terms, the metric system (which is the same as SI) is important because it's more coherent than the imperial system.

Explanation:

The metric system is far more used worldwide compared to the imperial system, where the imperial system is only officially used in three countries (U.S, Liberia, Myanmar).

There are multiple reasons why the metric system is important, but the most critical reason is that it's very easy to understand pertaining to calculations. The measurement system of SI is <em>designed</em> to make measurements/calculations easy to perform and understand. This is why scientists prefer using the metric system over imperial.

You can make some small comparisons:

--> Metric is consistently based on decimal numbers, while imperial uses different number systems (base 3, 8, 12, 14, 16, etc.,)
--> Metric works well with percentages, while imperial does not
--> Metric units are the same internationally, while some imperial units differ (i.e different pints, gallons, tons, etc.,)

There are fewer, simpler measurements in the metric system as compared to imperial where calculations start to get overcomplicated due to the amount of measurements/units in the system.

In layman's terms... metric is a boat on smooth water with perfect weather, while imperial is a boat on rough waters during a storm.
