3. The phosphate group at the 5'-end of DNA and the hydroxyl group at the 3'-end of DNA establish the DNA_______.
4._________ is the process that uses mRNA sequences to synthesize proteins.
5. Adenine binds to thymine, guanine binds to cytosine. This is known as________ .
6. A(n)________ consists of single long molecule of DNA associated with different types of proteins.
7. Complementary strands of DNA are meaning that one strand is oriented from 5' to 3' and the other from 3' to 5'________.
8. is the process that synthesizes single stranded RNA from a template DNA strand________.
9. Any one of the alternative forms of a particular gene is called a(n)___________ .

Answer 1

1. replication

2. gene

3. strand polarity

4. translation

5. complementary base pairing

6. chromosome

7. antiparallel

8. transcription

9. allele

Step-by-step 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
