Question

if the dna reads agcttacatgcc, the complementary rna strand is:

ucgaaugucggu
tcgaatgtacggt

session *

1 7:30am- 10:00am
2 11:00am-1:30pm

the genetic code consists of ______ letter \word\ also know as codons *

one
two
four
three

Explanation:

Determine the complementary RNA strand

The given DNA sequence is AGCTTACATGCC.
Using the base pairing rules for transcription:

• Adenine (A) pairs with Uracil (U) in RNA.
• Guanine (G) pairs with Cytosine (C).
• Cytosine (C) pairs with Guanine (G).
• Thymine (T) pairs with Adenine (A).

Applying these rules to each base:

• A -> U
• G -> C
• C -> G
• T -> A
• T -> A
• A -> U
• C -> G
• A -> U
• T -> A
• G -> C
• C -> G
• C -> G

The resulting complementary RNA sequence is UCGAAUGUCGGU.

Determine the length of a codon

A codon is a sequence of nucleotides on an mRNA molecule that codes for a specific amino acid. The genetic code is read in groups of three nucleotides, meaning each codon consists of three letters.

Answer:

Question 1

• (A) UCGAAUGUCGGU (Correct answer)
• (B) TCGAATGTACGGT

Question 2

• (A) one
• (B) two
• (C) four
• (D) three (Correct answer)
