please answer all especially 3 Proline has 4 codons 5 CCU 3

please answer all especially #3

Proline has 4 codons: 5\' CCU 3\' 5\' CCC 3 CCA CCG What are the anticodons? 3. In yeast, a single t can bind and recognize codons ending in U or C But if codons end in A or G separate tRNAs are required. 4.How many specific tRNAs for Proline does yeast require? 5. What are the anticodons? Analysis

Solution

The anticodons are:

1.3\'-GGI-5\'

2.3\'-GGG-5\'

3.3\'-GGU-5\'

4.3\'-GGA-5\'

Yes seperate tRNA are required if codon end in A or G because the 3\'-5\' chain becomes too big to fit into a single tRNA.The multiple tRNA can form bons and it can easily fit in between these bonds.
