Across
- 4. mutation A change in the structure or number of chromosomes, which can result in genetic disorders.
- 8. codon A codon (UAA, UAG, or UGA) that signals the termination of protein synthesis.
- 10. RNA A type of RNA that is a structural component of ribosomes, helping in the assembly of proteins.
- 13. A mutation where a part of one chromosome breaks off and attaches to another chromosome.
- 14. mutations Mutations that affect a specific gene, altering the sequence of nucleotides.
- 16. A mutation where one or more nucleotides are added to the DNA sequence.
- 18. Refers to the process where the DNA double helix is unwound, allowing access to the genetic code for transcription.
- 20. A mutation where one or more nucleotides are removed from the DNA sequence.
- 21. A sequence of three nucleotide bases (adenine, cytosine, guanine, and thymine/uracil) in mRNA that specifies a particular amino acid.
- 23. acids The building blocks of proteins, linked together by peptide bonds
- 24. mutation A type of mutation caused by insertions or deletions that shift the reading frame of the genetic code, altering the sequence of amino acid
- 26. code diagram A chart that shows the relationship between codons in mRNA and the amino acids they encode in protein synthesis.
Down
- 1. A mutation where a section of the chromosome is repeated
- 2. Large molecules made up of amino acids that perform various functions in the cell
- 3. A mutation where a section of the chromosome is reversed end-to-end.
- 5. Cellular structures where proteins are synthesized by translating mRNA into an amino acid sequence.
- 6. rna A type of RNA that carries genetic information from DNA in the nucleus to the ribosome for protein synthesis.
- 7. rna A type of RNA that brings amino acids to the ribosome, corresponding to the codons in the mRNA.
- 9. A chain of amino acids linked by peptide bonds, which folds into a functional protein
- 11. The start codon in mRNA, signaling the beginning of translation, which codes for the amino acid methionine.
- 12. polymerase An enzyme that synthesizes RNA from a DNA template during transcription.
- 15. A sequence of three nucleotides in tRNA that pairs complementary to a codon in mRNA.
- 17. The process by which mRNA is decoded outside the nucleus in the ribosome to produce a specific polypeptide chain (protein).
- 19. A type of mutation where one nucleotide is replaced by another.
- 22. bond The chemical bond formed between amino acids during protein synthesis.
- 25. Permanent changes in the DNA sequence that can lead to altered protein function.
