in translation, the dehydration synthesis reaction is catalyzed by which enzyme?

Answers

Answer:

hydrolysis

Explanation:

hydrolysis is the reverse of dehydration because it breaks a covenant bond by adding a water molecule

hope this was helpful ☆☆

In translation, the dehydration synthesis reaction is catalyzed by DNA polymerase enzyme. Therefore, the correct option is B.

What is DNA polymerase?

DNA polymerases are a group of enzymes that are responsible for catalyzing the synthesis of DNA. Their main function is to replicate the DNA. These enzymes work in pairs and a responsible for replicating two strands of DNA  in a tandem. DNA polymerases α and δ are primarily responsible for nuclear DNA replication. There are at least 15 DNA polymerases known to exist in humans.

Translation is the process by which the genetic code carried by mRNA is decoded to produce a specific sequence of amino acids that will form a protein. This process involves the ribosome, which is responsible for assembling the protein chain by joining amino acids in a specific order dictated by the mRNA sequence. Therefore, the correct option is B.

A piano player uses her hands for brief quick movements. Which muscle fiber type would you therefore predict to be predominant in these muscles

Answers

For brief quick movements, which muscle fiber type would you therefore predict to be predominant in these muscles...Fast twitch muscle fiber type.

There are three types of muscle tissue. 1. Cardiac 2. Smooth 3. skeletal muscles. The skeletal muscle are involved in voluntary movements of the body.

Since the player uses her hand in a voluntary way of movement, therefore she makes use of her skeletal muscles.

With regards to the skeletal muscles, there are two types with regards to speed, we have the slow twitch and the fast-twitch.

The fast-twitch muscle fiber aids in fast movement of the body but for shorter periods compared to the slow twitch.

gene expression is determined by several factors, including

Answers

Hi! Thanks for asking your question here on Brainly!

Answer:

Chemicals in the body of a living organism is one of the many factors determined in gene expression.

Explanation:

The presence of drugs and/or chemicals in a living organism's environment, this can also influence gene expression in the organism.

Hope this helps :D Happy Holidays!

Expressivity can be impacted by a number of elements, such as genetic make-up, exposure to dangerous chemical substances, other environmental effects, and age.

What are the factors that affect gene expression?

The level of transcription is where the majority of control over gene expression is exerted, and this is mostly due to the fact that proteins bind to certain locations on DNA.

It is possible for environmental elements such as nutrition, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens to have an effect on which of an animal's genes are expressed, which in turn has an effect on the animal's phenotype.

how much blood is filtered by the kidneys each day?

Answers

Answer:

Many times a day, your blood circulates through your kidneys.

Explanation:

Approximately 170 liters per day and 7 liters per hour. About 150 quarts of blood are filtered by your kidneys in a single day relavent to 44 gallons. The tubules are responsible for returning water and other substances to your blood following their filtering through your glomeruli. Approximately one or two quarts of the water becomes urine.  

now you’ll examine an operon that undergoes negative and positive control. the ara operon in e. coli codes for enzymes that metabolize the sugar arabinose, which e. coli can use for energy. as you can see in the diagram, the regulatory protein arac can act as both an activator and a repressor of the ara operon.

Answers

The lac operon is known to be able to undergoes negative and positive control.

The diagram based on the 4 table arrangement is filled up below (Right to left);

In the presence of arabinose:  initiator, activator,  yes,  yes.

In the absence of arabinose: initiator and operator, repressor, no, no.

If a mutation prevents arabinose from biding to AraC: initiator and operator, repressor, no, no.

If arabinose is present but a mutation and AraD enzyme renders it non-functional: initiator, activator, yes, no.

The metabolism of the sugar arabinose is known to be influenced  by an operon that is said to undergo both positive control and negative control.

Transcription of the ara operon is lead by the regulatory protein AraC, which then bound to the DNA.

When arabinose is present, it binds to AraC, and both parts of the AraC dimer are then also bound to the initiator, making transcription to move foreword.

When arabinose is absent, one part of the AraC dimer is often bounded to the initiator, while the other part is bounded to the operator, thereby hindering transcription.
