Question

protein synthesis problem 1
codon wheel or table is needed to find the amino acid. please do your own work. i need to know that you know how to do these processes.

dna coding strand	a	t	g	a	c	t	t	g	g	c	t	a	c	c	g
mrna	a	u	g	a	c	u	u	g	g	c	u	a	c	c	g
codon (3 letters)	aug	acu	ugg	cua	ccg
amino acid (from codon wheel)	met	thr	trp	leu	pro

1. use the coding strand to create the template strand.
2. what process does this represent?

1. what enzyme performs this function?

1. use the template strand to form complementary bases to create the mrna.
2. what process does this represent?

1. what enzyme performs this function?

1. from the mrna, write the codons.

Explanation:

1. DNA base pairing rules: A pairs with T, G pairs with C.
2. The process of creating a DNA template strand from a coding strand is DNA replication, which uses DNA polymerase.
3. mRNA uses U instead of T; base pairs with template strand (A-U, T-A, G-C, C-G).
4. Creating mRNA from DNA template is transcription, done by RNA polymerase.
5. Codons are 3 consecutive mRNA bases, read sequentially.
6. Amino acids are matched to codons via standard genetic code.
