Across 6. The process in which cellular ribosomes create proteins 7. The process by which messenger RNA is synthesized from a DNA template resulting in the transfer of genetic information from the DNA molecule to the messenger RNA. 8. The process by which such a change occurs in a chromosome, either through an alteration in the nucleotide sequence of the DNA coding for a gene or through a change in the physical arrangement of a chromosome. 11. The addition, as by mutation, of one or more nucleotides to a chromosome 12. A sequence of three adjacent nucleotides in transfer RNA that binds to a corresponding codon in messenger RNA and designates a specific aminoacid during protein synthesis. 14. The first codon of a messenger RNA 15. The loss, as through mutation, of one or more nucleotides from a chromosome

Down 1. The occurrence of a repeated section of genetic material in a chromosome 2. A chromosomal defect in which a segment of the chromosome breaks off and reattaches in the reverse direction. 3. The process by which biological cells generate new proteins 4. The set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated into proteins by living cells 5. An adapter molecule composed of RNA, 7. A type of chromosomal abnormality in which A chromosome breaks and a portion of it reattaches to a different chromosome 9. A nucleotide triplet within messenger RNA that signals a termination of translation 10. A large family of RNA molecules that convey genetic information from DNA to the ribosome 13. The RNA component of the ribosome, and is essential for protein synthesis in all living organisms
