Biology Unit 5

5. Segment of newly formed DNA on the lagging strand, connected together ligase during DNa replication.
9. 1st step of protein synthesis - takes place in nucleus and creates strand of mRNA.
13. Organelle where proteins are made.
14. Macromolecule made of amino acids for enzymes, transport, and cell structures.
15. 3 letter sections of mRNA that codes for an amino acid.
16. Replication strand of DNA that adds nucleotides moving toward helicase.
17. Type of mutation that changes who sections of a chromosome nu adding, deletion, inverting, and moving sections.
18. When a base is added or deleted and changes all amino acids after the mutation.
21. Double stranded nucleic acid that has all genetic material, bases include A, T, G, and C, and is located in the nucleus.

1. 3 letter section of tRNA that matches to a codon of mRNA.
2. Type of mutation that only affects one gene by substituting, adding, or deleting bases.
3. Enzyme used to unzip the DNA molecule during DNA replication.
4. Replication strand of DNA that adds nucleotides moving away from helicase.
6. Refers to DNA and histone proteins that make up chromosomes.
7. Monomer of proteins - made of sugar, phosphate, and nitrogen base.
8. Strand of RNA created during transcription - Each 3 letter section is called a codon.
10. Double stranded nucleic acid that has all genetic material, bases include A, T, G, and C, and is located in the nucleus.
11. Type of RNa used during translation, carries the amino acid and matches up with the mRNA codon.
12. When a base is substituted and only changes 1 amino acid.
19. Single stranded nucleic acid used by cells, has bases A, U, G, and, C types of include mRNA, tRNA, and rRNA.
20. 2nd step of protein synthesis - takes place at a ribosome and uses tRNA molecules to assemble amino acids into proteins.
