Cech and Altman discovered the self-replication and biocatalytic properties of RNA. Option B.

<h3>What did Cech and Altman discover?</h3>

After several years of research, Cech and Altman discovered that, apart from being inheritable molecules and being involved in protein synthesis, RNA functions as a biocatalyst -just like enzymes- .

These scientists discovered that RNA shares with DNA the capability of transmitting genetic information and with proteins the capability of facilitating chemical reactions as a biocatalyst.

They could prove that,

  • RNA can self-replicate because it carries the genetic information needed to do it and <u>does not need </u>other proteins.
  • It has a significant protagonism in cellular metabolism.

In the enzyme's and additional energy absence, the molecule can start its maturation process, catalyzing reactions by itself. Cech named this RNA form with enzymatic function ribozyme.

This was a significant discovery since it demonstrated that not only proteins were involved in biological reactions.

the northern leopard frog, tree frog, and wood frog are all different species of frogs. why is having a scientific name for each
guapka [62]

These names are significant because they enable clear communication about animal species among people all across the world.

<h3 /><h3>What are the significance of northern leopard frogs?</h3>

In ponds where it lives, the northern leopard frog is probably a significant indicator of the water's quality. This species is an essential component of the food chain, and tadpoles, which are the main eaters of algae in ponds, can have a big impact.

<h3>What distinguishes tree frogs from other frog species?</h3>

These frogs are most easily recognized by their feet, which have claw-shaped toe bones as their last bone. They can also climb trees thanks to toe pads with small suction cups and extraskeletal structures on their toes. They are available in a number of hues, the most popular being green, gray, or brown.

A protein kinase can phosphorylate an enzyme and activate it by
Zinaida [17]

Answer:

Signal transduction

Explanation:

A signal molecule binds to a receptor.

A conformational change in the signal-receptor complex activates an enzyme.

Second messenger molecules are released.

Protein kinases are activated.

Target proteins are phosphorylated.can be defined as the process in which a physical or chemical signal is transmitted through a cell as a series of molecular events inform of protein phosphorylation are catalyzed by protein kinase and this ultimately result into a cellular response. However, the protein that is responsible for the detection of stimuli is commonly refers to as receptors or sensor.

What is an example of a biotic factor in a biome?: * A. scavengers B. producers C. soil
charle [14.2K]

Answer:

The correct answer is A. scavengers and B. producers

Explanation:

Two types of factors are found in a biome biotic and abiotic factor. All the living things in any biome comes under biotic factors like animals, plants, and microbes and all the non-living things present in the biome are non-biotic factors for example soil, temperature, air, water, salt, etc.

So biome is made up of both living and non-living factors. Scavengers are the organisms that feed on dead and decaying matter and producers are the organisms that make their own food. Most of the producers are plants.  

So both scavengers and producers are living organisms therefore both are examples of biotic factors.
