Eukaryotic cells contain DNA in the mitochondria and chloroplasts (in addition to the nucleus). Is the organization of DNA in th
Elena L [17]

Answer:

The DNA is more closer to bacteria.

Explanation:

Mitochondria and chloroplast are considered as semi-autonomous organelle because they contain their own genetic material. The mitochondria and chloroplast evolution can be explained by the endosymbiont theory.

The DNA of mitochondria and chloroplast are more closely related to bacterial chromosome rather than eukaryotic chromosome.  Both the organelle and bacterial DNA are double stranded and  their translation can be inhibited by the chloramphenicol. Some of their replicating enzymes also show similar characteristics.

Thus, the DNA is more closer to bacteria.

Define the following terms. Drag and drop the words into the appropriate blanks to complete the sentences.
FrozenT [24]

Answer:

1. replication

2. gene

3. strand polarity

4. translation

5. complementary base pairing

6. chromosome

7. antiparallel

8. transcription

9. allele

Explanation:

1. Replication is the process by which DNA is duplicated or the process of making another copy of DNA.

2. Gene is the physical unit of heredity i.e a segment of DNA transferred from parents to offsprings. A gene also encodes a useful products such as protein.

3. A DNA strand is a polar molecule, which is attributed to the phosphate group at the 5'-end of DNA and the hydroxyl group at the 3'-end of DNA.

4. Translation is the process whereby the information in a mRNA molecule is used to synthesize a protein.

5. Complementary base pairing is a phenomenon whereby Adenine (A) binds to thymine (T), guanine (G) binds to cytosine (C).

6. A chromosome contains of single long molecule of DNA coiled together around histone proteins. The chromosome is associated with different types of proteins.

7. In the double-stranded DNA molecule, one strand runs from 5' to 3' and the other runs from 3' to 5'. This is called ANTIPARALLEL nature of DNA.

8. Transcription is the process by which a DNA molecule is used to synthesize a mRNA single strand.

9. Allele is the alternative or contrasting form of a gene. Each allele is contributed by each parent
