During translation, nucleotide base triplets (codons) in mRNA are read in sequence in the 5’ → 3’ direction along the mRNA. Amin
Paladinen [302]

Answer:

The question is incomplete, it lacks the mRNA sequence. The sequence is as follows:

5′−AUGGCAAGAAAA−3′

The answer is Met-Ala-Arg-Lys

Explanation:

Gene expression in living organisms involves the process of transcription and translation. Transcription is the synthesis of a complementary strand of mRNA from a DNA template while translation involves using the transcibed mRNA as a template to synthesize amino acid sequence (proteins).

In the RIBOSOME, where the synthesis of protein occurs, the mRNA nuceleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies a particular amino acid. The collection of all codons is the genetic code. Hence, for a specific mRNA sequence that reads 5′−AUGGCAAGAAAA−3′. The nucleotides will be read three at a time starting with AUG which is a codon that encodes METHIONINE.

Next, GCA is a codon that encodes ALANINE

Next, AGA is a codon that encodes ARGININE

Finally, AAA is a codon that encodes LYSINE.

Hence, the amino acid sequence using the above mRNA sequence, will read: Met-Ala-Arg-Lys

Does this show the geocentric or heliocentric idea of the solar system? Explain the difference.
ASHA 777 [7]

It shows the heliocentric idea of the solar system. In this view, the sun is at the center of the

solar system with planets orbiting around it. In the geocentric view, the earth is at the center of

the solar system.

Which of the following processes includes all the others?
Vinvika [58]

Answer:

Passive transport.

Explanation:

The transport of molecules across the plasma membrane can occur by the two process- active transport and passive transport. No amount of energy is required during the active transport.

Passive transport includes the diffusion and osmosis. Both the diffusion and osmosis do not require energy and the molecules move down from the region of higher concentration towards the region of lower concentration. Small molecules, ions and proteins can go through the passive transport.

Thus, the correct answer is option (c).
