drag the words into the correct boxes

1. brings amino acids to the ribosome for assembling the protein.
2. a biomolecule that is made up of a chain of amino acids is a
3. an is any part of a gene that will encode a part of the final mature rna produced by that gene after introns have been removed by rna splicing
4. an enzyme that synthesizes the mrna from the dna template
5. the process of translating the sequence of a messenger rna (mrna) molecule to a sequence of amino acids is
6. a is a segment of dna that codes, or contains instructions for building a specific protein.
7. is the sequence of events in which the primary mrna transcript from a gene acquires its mature form - introns are removed and exons are spliced together, a 5 cap is attached and a poly - a tail is attached to the 3 end of the mrna transcript.
8. non - coding regions of an mrna transcript, or the dna encoding it, that are eliminated by splicing during mrna processing are called
9. is the first of several steps of dna based gene expression in which a particular segment of dna is copied into mrna by the enzyme rna polymerase.
10. is a type of non - coding rna which is the primary component of ribosomes.
11. are the type of bonds which join amino acids.
12. are proteins which remove introns from a transcribed pre - mrna.
13. a sequence of non - coding dna found in the promoter region of genes is the
14. is a single - stranded molecule that carries genetic code from dna in a cells nucleus to ribosomes for translation.
15. a region of dna where transcription of a gene is initiated is called a
16. the monomers or building blocks of proteins are

Explanation:

1. tRNA (transfer - RNA) is responsible for bringing amino acids to the ribosome for protein assembly.
2. Proteins are biomolecules made up of chains of amino acids.
3. Exons are parts of a gene that encode part of the final mature RNA after introns are removed.
4. RNA polymerase synthesizes mRNA from a DNA template.
5. Translation is the process of converting mRNA sequence to an amino - acid sequence.
6. A gene is a DNA segment that codes for a specific protein.
7. mRNA processing involves removing introns, splicing exons, adding a 5' cap and a 3' poly - A tail.
8. Introns are non - coding regions removed during mRNA processing.
9. Transcription is the first step of gene expression where DNA is copied into mRNA by RNA polymerase.
10. rRNA (ribosomal RNA) is a non - coding RNA and a primary component of ribosomes.
11. Peptide bonds join amino acids.
12. Spliceosomes are proteins that remove introns from pre - mRNA.
13. The TATAA box is a non - coding DNA sequence in the promoter region.
14. mRNA (messenger RNA) carries genetic code from DNA to ribosomes for translation.
15. A promoter is a DNA region where transcription is initiated.
16. Amino acids are the monomers of proteins.
