From DNA to Proteins Unit Crossword
Name ____________________
Across
1. – the process where a strand of
messenger RNA or mRNA is
converted into a sequence of amino
acids to build a protein.
3. –the making of an RNA
molecule from a DNA template
5. A change of the DNA
sequence within a gene or
chromosome of an organism
resulting in the creation of a new
character or trait not found in the
parental type.
6. -a type of RNA that binds to s
specific amino acids and carries
it to the ribosome during
translation.
7. –a biomolecule composed of
stands of Amino Acids
9. - The bases of both DNA and
RNA are almost always found as
paired bases. In DNA Adenine
pairs with Thymine and Guanine
pairs with Cytosine. The pairing
is the same in RNA except Uracil
replaces Thymine
11. - (DNA) a molecule
composed of a deoxyribose
sugar, a phosphorus group and a
nitrogen base. The molecule that
contains the instructions for all of
the cells function.
12. – a sequence of three bases
of mRNA the specifies or codes
for a specific amino acid to be
incorporated into a protein. Certain codon signal the start and end of protein synthesis.
15. – a type of mutation that results in a shift in the coding sequence of DNA resulting in a completely different protein being produced.
16. – an Enzyme that catalyzes the bonding of free RNA nucleotides into a continuous strand using RNA nucleotides that are complementary to the
DNA strand being transcribed.
17. –Nitrogen Base of DNA that hydrogen bonds to Adenine
19. – a protein that DNA wraps around when coiling and condensing to form chromosomes.
20. –a molecule composed of ribose sugar, phosphate groups and Nitrogen Bases. This molecule helps transfer the information from the DNA in
the nucleus to the ribosomes in the cytoplasm where it helps build proteins.
21. polymerase –Enzyme that bonds to DNA nucleotides together into a continuous strand using the pre-existing DNA stand as a template.
22. –Nitrogen Base of DNA and RNA that hydrogen bonds to Cytosine
23. – a 5 carbon sugar that is used in RNA
Down
2. (rRNA) –strands of RNA that make up part if the ribosomal subunits.
4. –Nitrogen base of DNA and RNA that hydrogen bonds to Thymine in DNA and Uracil in RNA.
8. –Process in which an identical copy of an existing DNA strand is duplicated.
10. – Type of molecule that forms an important part of nucleic acid, composed of a nitrogen-containing ring structure. Hydrogen bonds between
bases in opposing complementary strands link the two strands of a DNA double helix.
13. –a 5 carbon sugar used in DNA
14. –an individual sub unit that makes up DNA and RNA, made up of a Sugar, a phosphate and a nitrogen base.
18. –Nitrogen base of RNA that hydrogen bonds with Adenine. Replaces Thymine
