During bacterial translation, initiation occurs in three steps. Which step is last?.
Olegator [25]

Bacterial translation is initiated in three steps. In the final step, the large ribosomal subunit binds to the mRNA.

The ribosome's translation of an mRNA molecule occurs in three stages: initiation, elongation, and termination. The small ribosomal subunit binds to the beginning of the mRNA sequence during initiation. Most eukaryotic mRNAs initiate translation by binding Met-tRNAiMet to a 40S subunit, followed by ribosomal attachment at the 5′ end of an mRNA, scanning to the initiation codon, and joining with a 60S subunit to form an 80S ribosome. The stages of translation should be completed in the following order: Initiation, Elongation, and Termination.

Consider the factors that affect muscular strength. Read each scenario and identify whether each would result in a stronger or w
nlexa [21]

Muscles are required in breathing, talking, running, walking, and any body movement. Actin and myosins are protein filaments present in muscle cells that help to contract and relax or change the shape of muscles. Muscles are responsible for the movement or motion of organisms. Joints are the connection between two or more bones. Most joints are mobile.

Muscle strength is determined by several factors. Some of those are the physical shape, size, and innervation of the muscles.  

Weak contraction

  • Potassium accumulates in the sarcoplasm.
  • Contracted lower sarcoplasm pH.
  • Begin contraction with muscle already 50%.
  • The circular arrangement of muscle fascicles.

Stronger contraction

  • Increase in muscle belly circumference.
  • A lesser proportion of motor neurons to muscle fibers.
  • Increased recruitment.
  • Increased stimulus frequency.

Which of the following best describes the relationship between the sun and Jupiter?
Softa [21]

Answer: B) Jupiter and the sun have a similar composition.

Explanation:The only significant difference between the sun and Jupiter is in the sizes i.e jupiter is smaller compared to the size of the sun.

However their similarities is in their composition i.e what they are made up (helium and hydrogen).

The core of Jupiter is made up of liquid metallic hydrogen and the sun's core or center is also made up 34% mass plasma of hydrogen.

So option B (Jupiter and the sun have a similar composition) best describes the relationship between Jupiter and the sun.

Explain complex enzyme ​
mrs_skeptik [129]

Answer:

All enzymes are mostly protein, but many are only protein. These enzymes are known as simple enzymes. Enzymes that contain other things, “complex enzymes,” are called holoenzymes. A holoenzyme has two parts. The protein part is called the apoenzyme.

The enzyme substrate complex is a temporary molecule formed when an enzyme comes into perfect contact with its substrate. ... The substrate causes a conformational change, or shape change, when the substrate enters the active site. The active site is the area of the enzyme capable of forming weak bonds with the substrate.

Enzymes are protein molecules in cells which work as biological catalysts. Enzymes speed up chemical reactions in the body, but do not get used up in the process, therefore can be used over and over again. Almost all biochemical reactions in living things need enzymes. ... The study of enzymes is called enzymology.
