Answer:

The purpose of the Miller and Urey experiment was to see if organic compounds that could sustain life be created spontaneously in Earth's early atmosphere. They wanted to see if complex molecules of life (eg. Amino acids, etc.) could be created using natural chemical reactions when Earth had harsh conditions.

Given the mRNA sequence below, what would tRNA anticodons be in response? A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A
Lesechka [4]

Answer:

U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U

Explanation:

The mRNA (messenger RNA) is produced via the process of TRANSCRIPTION, which is the first stage of gene expression in living cells. The mRNA sequence formed is further read in the ribosomes in a group of three nucleotides called CODONS. This reading is done by another type of RNA called transfer RNA (tRNA).

The tRNA uses a set of three nucleotide bases that are complementary to that of the mRNA codons called ANTICODON. The anticodons are complementary to the mRNA codon i.e. A on the mRNA sequence will be read and recognized by U on the tRNA anticodon.

Hence, given the mRNA sequence: A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A, the tRNA anticodons that will read this sequence will be: U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U
