Molecular Biology

5. A codon that signals to ribosomes to begin translation; codes for the first amino acid in a protein.
7. A process by which mRNA is decoded and a protein is produced.
8. These are the units that are repeatedly joined together to form a strand of DNA.
12. It is a process of copying a nucleotide sequence of DNA to form a complementary strand of mRNA
14. It is the nucleic acid molecule that allows for the transmission of genetic information and protein synthesis.
15. Both polypeptide and proteins are made up of these.

1. It is a process by which copies of DNA are made.
2. A mutation that involves a substitution of only one nucleotide.
3. a codon that signals to ribosomes to stop protein trnslation.
4. A model that compares the structure of a DNA molecule, in which two strands wind around one another, to that of a twisted ladder.
6. In a molecule of double-stranded DNA, the amount of Adenine present is always equal to the amount of?
9. A form of RNA that brings amino acids to ribosomes during protein synthesis
10. A form of RNA that carries genetic information from the nucleus to the cytoplasm, where it serves as a template for protein synthesis.
11. It is a set of three nucleotide in a tRNA molecule that binds to a complementary mRNA codon during translation
13. RNA that is in the ribosome and guides the translation of mRNA into a protein; also is synthesized in the nucleolus.
