Convert the following DNA sequence into its RNA equivalent and then using the genetic code, convert that RNA sequence into the amino acid sequence.

5’–TACTTCTTCAAGACT-3’

For this above DNA sequence, what information is contained in the genetic code for the first and last codon?

To convert the given DNA sequence into its RNA equivalent, we need to replace the thymine (T) nucleotides with uracil (U) nucleotides. The given DNA sequence: 5’–TACTTCTTCAAGACT-3’

RNA sequence: 5’–UACUUCUUCAAGACU-3’

To convert this RNA sequence into an amino acid sequence using the genetic code, we need to break the RNA sequence down into codons. Codons are groups of three nucleotides that code for a specific amino acid. The genetic code is a set of rules that specifies which codon codes for which amino acid.

First, let's identify the codons in the RNA sequence:

Codons: UAC, UUC, UUC, AAG, ACU

Now, using the genetic code, we can determine the amino acid sequence corresponding to these codons:

UAC codes for the amino acid tyrosine (Tyr)
UUC codes for the amino acid phenylalanine (Phe)
UUC codes for the amino acid phenylalanine (Phe)
AAG codes for the amino acid lysine (Lys)
ACU codes for the amino acid threonine (Thr)

So, the amino acid sequence for the given DNA sequence is: Tyr-Phe-Phe-Lys-Thr

Now, let's analyze the information contained in the genetic code for the first and last codon:

The first codon is UAC, which codes for the amino acid tyrosine (Tyr). It provides information about the specific amino acid that should be incorporated at the beginning of the protein sequence.

The last codon is ACU, which codes for the amino acid threonine (Thr). It provides information about the specific amino acid that should be incorporated at the end of the protein sequence.

Each codon in the genetic code contains information about a specific amino acid, allowing the correct sequence of amino acids to be generated during protein synthesis.

To convert the given DNA sequence into its RNA equivalent, you need to replace each occurrence of "T" with "U".

Given DNA sequence: 5'-TACTTCTTCAAGACT-3'

RNA sequence: 5'-UACUUCUUCAAGACU-3'

Now, let's identify the first and last codons in the RNA sequence to determine the amino acids they code for.

First codon: UAC
Last codon: ACU

To decode the codons and determine the corresponding amino acids, you can use the genetic code table.

Using the genetic code:

UAC - Codes for the amino acid Tyrosine (Y)

ACU - Codes for the amino acid Threonine (T)

Therefore, the first codon (UAC) in the RNA sequence codes for the amino acid Tyrosine (Y), and the last codon (ACU) codes for the amino acid Threonine (T).
