Answer:
This question is asking to do the following:
Replicate the DNA sequence
Transcribe the complementary DNA into mRNA
Translate the mRNA codons into amino acid sequence
Give the function of mRNA
Please find the detailed answer to this question below
Explanation:
- DNA replication is a process whereby the content of DNA (genetic material) is doubled i.e. duplicated. In other words, another copy of DNA is made from one a DNA template. The principle of DNA replication follows the complementary base pairing rule i.e. A-T, G-C
Original DNA template- A T G G G T C T A G C G A A A G A T
After DNA replication-
Complementary DNA strand- T A C C C A G A T C G C T T T C T A
- Transcription is the process whereby a DNA template used to synthesize a mRNA strand. In this case, the complementary DNA sequence above will be transcribed into a complementary mRNA sequence. Note that Uracil replaces Thymine in RNA.
Complementary DNA strand- T A C C C A G A T C G C T T T C T A
After transcription
mRNA strand- A U G G G U C U A G C G A A A G A U
- Translation is the process by which a amino acid sequence is synthesized from a mRNA sequence. The sequence of the mRNA is read in a group of three bases called CODON. Each codon specifies an amino acid. In this case; the mRNA sequence is A U G G G U C U A G C G A A A G A U
After translation using the genetic code, the amino acid sequence is:
Methionine- Glycine- Leucine- Alanine- Lysine- Aspartic acid
Note:
AUG codes for Methionine (Met)
GGU codes for Glycine (Gly)
CUA codes for Leucine (Leu)
GCG codes for Alanine (Ala)
AAA codes for Lysine (Lys)
GAU codes for Aspartic acid (Asp)
- mRNA, which means messenger RNA, is a type of RNA molecule whose major function is to transport genetic information out of the nucleus into the cytosol in order for translation to take place. In contrast to DNA, which is a storage molecule, mRNA is a transporting/carrier molecule that encodes genetic information.
