The amino acid sequence of the polypeptide is determined by the codon sequence on the mRNA strand. Therefore, option (A) is correct.
What is a codon?The genetic code is a system of principles that all living cells follow in order to decipher the information that is contained inside their genetic material and turn it into proteins.
The genetic code is comprised of a set of three-letter combinations of nucleotides known as codons. Each codon is associated with a particular amino acid or a stop signal. In 1961, Francis Crick and several of his colleagues were the first people to formally articulate the idea of codons.

Which is the final event that occurs when a star is forming?
The outer layer of the star expands.
Gravity pulls gas and dust together.
A black hole forms as the core collapses.
Nuclear fusion begins under high pressure.
Answer:
D. Nuclear fusion begins under high pressure.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
Some of the examples of stars are;
Canopus.Sun (closest to the Earth)Betelgeuse.Antares.Vega.Stars are typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He). The chronological order in which the formation of a star occur are;
1. Gravity pulls gas and dust together to form dense cores.
2. A protostar forms as mass increases.
3. Nuclear fusion begins under high pressure.
Hence, the final event that occurs when a star is forming is that nuclear fusion begins under high pressure.

Which of the following best describes the compositional layers of the earth? a. All layers of the Earth below the crust are liquid. b. The only liquid layer of the earth is the mantle. c. The crust floats on top of the outer core. d. Some layers of the earth are liquid, and some are solid. Please select the best answer from the choices provided A B C D
Answer:
The answer to this question is "D" Some layers of the earth are liquid, and some are solid.Explanation:
Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid.
The option that correctly describes the compositional layers of the earth is : ( D ) Some layers of the earth are liquid, and some are solid.
Earth compositionThe earth is composed of the Core, mantle, and crust which are categorised based their varying composition. The crust consists of the oceanic crust and continental crust. WhileThe lithosphere is composed of both the crust and the portion of the upper mantle which are similar to brittle rigid solid.

Which step in the process of photosynthesis is dependent on light energy?
A.splitting of water into hydrogen and oxygen
B.combining carbon and oxygen into carbon dioxide
C.splitting carbon dioxide into carbon and oxygen
D.combining hydrogen and oxygen to form water
Answer:
D. Combining hydrogen and oxygen to form water.
Explanation:
The process of photosynthesis which is dependent on light energy is the
combining of hydrogen and oxygen to form water.
Photosynthesis involves the reaction between carbondioxide and water to
form Starch and oxygen. The water molecules however have to be split
because of movement of electrons in which the water become oxidized and
carbondioxide reduced.
This process however have to be done in the presence of sunlight which
serves as a precursor.
