![**Task: Complementary DNA Strand**
Write the complementary DNA strand for the following DNA base sequence:
**5' CTCAAG 3'**
[Box for answer: 3' __________ 5']
---
**Explanation:**
In DNA, the bases pair as follows:
- Cytosine (C) pairs with Guanine (G)
- Thymine (T) pairs with Adenine (A)
- Adenine (A) pairs with Thymine (T)
- Guanine (G) pairs with Cytosine (C)
Using this information, the complementary strand for the given sequence can be determined by matching each base with its pair, writing it in the opposite 3' to 5' direction.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F19398810-45a6-4031-9f44-c561c2949034%2F1b7b439c-e7c4-48c5-a1cd-9c0cfc342060%2F5uf7wgt_processed.png&w=3840&q=75)

**a. The sequence of a short DNA segment is ATGGCAATAC. What names are given to the two ends (termini) of the molecule?**
- [Dropdown] end
- [Dropdown] end
**b. Label the ends of the DNA segment.**
- [Dropdown] ATGGCAATAC [Dropdown]
**c. The sequence of a short RNA segment is GCCGUUAUGCA. Label the ends of the RNA segment.**
- [Dropdown] GCCGUUAUGCA [Dropdown]
**Explanation:**
In molecular biology, DNA and RNA molecules have two distinct ends referred to as the 5’ (five prime) and 3’ (three prime) ends. These denote the directionality of the nucleic acid strands and are critical in processes like replication and transcription.
- **5’ End:** This end of the DNA or RNA strand is characterized by a phosphate group attached to the fifth carbon of the sugar ring.
- **3’ End:** This end has a hydroxyl group attached to the third carbon of the sugar ring.
The labels should be placed correctly to indicate the orientation of both DNA and RNA sequences. Understanding and naming these termini is essential for accurate communication in genetics and molecular biology.
In the exercise above, the user is prompted to choose the correct labels for these ends using dropdown menus.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F19398810-45a6-4031-9f44-c561c2949034%2F1b7b439c-e7c4-48c5-a1cd-9c0cfc342060%2F01ahn4c_processed.png&w=3840&q=75)
