QuestionGiven the DNA template strand 3' GTCGAACGT 5', write the amino acid sequence in the N-terminal to C-terminal direction. Note: Enter the amino acids using their three-letter designations. Put a hyphen between each amino acid. (for example, Glu-Asp-Val). Refer to a codon table. amino acid sequence: \square B I U x2x_{2} x2x^{2}

Studdy Solution

STEP 1

What is this asking? Given a DNA template strand, we need to figure out the amino acid sequence it codes for, writing it from start to finish. Watch out! Remember, we're given the *template* strand, not the coding strand!
Also, don't forget to write the amino acids in the correct order, from the N-terminal to the C-terminal end.

STEP 2

1. Find the coding strand
2. Find the mRNA sequence
3. Translate the mRNA to amino acids

STEP 3

Alright, let's **kick things off**!
We're given the **template strand**: 33' GTCGAACGT 55'.
To find the **coding strand**, we need to find its complement.
Remember, A pairs with T, and G pairs with C.
Also, the coding strand runs 55' to 33'.

STEP 4

So, the **coding strand** is 55' CAGCTTGCA 33'.
We just swapped each base for its complement and flipped the direction!

STEP 5

Next up, we need to find the **mRNA sequence**. mRNA is almost identical to the coding strand, except T is replaced by U.

STEP 6

So, our **mRNA sequence** is 55' CAGC­UUGCA 33'.
See? Just swapped those Ts for Us!

STEP 7

Now for the **grand finale**: translating our mRNA into **amino acids**!
We'll read the mRNA sequence in **codons**, which are groups of three bases.
Let's break it down: CAG, CUU, and GCA.

STEP 8

Using a **codon table**, we can find which amino acid each codon codes for.
CAG codes for **Gln**, CUU codes for **Leu**, and GCA codes for **Ala**.

STEP 9

Finally, we write the amino acids in the correct order, from **N-terminal to C-terminal**: Gln-Leu-Ala.
Boom!

STEP 10

amino acid sequence: Gln-Leu-Ala
