10 DN A and RNA: Structure and Function Name Lab section may collect These end-ofesercise questions so, pleare Aill in your name and kob secin End-of-Exercise Questions Directions: Use the complete codon dictionary (table 10.2) to answer these questions 1. Use the base equence for mRNA to complete the columns on the following table (table 10.4). (Use the mRNA Rememsn the table. Do not use the mRNA hase pair sequence from the exercise you just completed.) sequence shown in the Remember that complemeetary base pairing is the key. Refer to table 10.3 if you have problems Table 10.4 Complementary Base Pairing Amine Acid DNA RNA Complement Gene 2. Use one word to describe the relationship between the gene sequence and the mRNA sequence in table 10.4 3. Describe in a sentence the relationship between the gene sequence and the tRNA sequence in table 10.4. 4. What will the sequence of mRNA nucleotides be if the following represents the bases in a DNA molecule of a structural gene? DNA gene mRNA . Ifa structural gene contains 300 DNA nucleotides, how many amino acids will be used in the protein synthe- sis process? 121

Answer 1

2)

Complementary

3)

​​​​​​anticodon sequence on t-RNA is same as gene sequence at its respective site of gene sequence but there is 'U' instead of 'T' in t-RNA sequence.

4)

mRNA sequence :

UUA CCA GGU GGC GAC

5)

100 amino acids will be used in protein synthesis as 1 amino acid is used per 3 nucleotide in protein synthesis.
