Unit 5 Biology

3. gene mutation-when a base is added or deleted and changes all amino acids after the mutation.
5. masubstituting made of amino acids-used for enzymes, trnasport, and cell structures.
7. type of mutation that changes whole sections of a chromosome by adding, deletion, inverting, or moving sections.
9. 3 letter sections of mRNA that codes for an amino acid.
11. refers to DNA and histone proteins that make up chromosomes.
12. single stranded nucleic acid used by cells, has bases a,u,g,and c, types include mRNA,tRNA, and rRNA.
15. used to organize DNA to fit in the nucleus, together with DNA makes up chromatin.
19. monomer of proteins-these are carried by tRNA molecules during translation.
24. replicating strand of DNA that adds nucleotides moving away from helicase.
25. 3 letter section of tRNA that matches to a codon of mRNA.

1. replicating strand of DNA that adds nucleotides moving toward helicase.
2. enzyme used to unzip the DNA molecule during DNA replication.
4. gene mutation-when a base is substituted-changes only 1 amino acid.
6. section of a gene that codes for protein.
8. segment of newly formed DNA on the lagging strand, connected together by ligase during DNA replication.
10. making a copy of DNA, occurs during the s phase of interphase.
13. part of a nucleotide along with a 5 cabon sugar and phosphate group.
14. double stranded nucleic acid that has all gnetic material, bases includ a,t,g, and c, located in the nucleus.
16. type of RNA used during translation, carries the amino acid and matches up with the mRNA codon.
17. section of DNA that codes for a protein, has introns and exons-passed from parent to offspring.
18. type of mutation that only affects one gene by subsituting, adding, or deleting bases.
20. strand of RNA created during transcription-each 3-letter section us called a codon.
21. monomer of nucleic acids-made of a sugar, phosphate, and nitrogen base.
22. organelle where proteins are made.
23. section of a gene between exons-does not code for proteins, "junk".
