Genetics

2. Thread-like structures made of DNA and proteins that carry genetic information.
3. The cell structure where proteins are made by linking amino acids together.
6. A molecule that carries genetic instructions for growth, development, and functioning of all living things.
8. A type of RNA that carries genetic instructions from DNA to the ribosome.
11. The passing of traits from parents to offspring through genes.
12. A type of RNA that brings amino acids to the ribosome to build proteins.
14. Proteins that help organize DNA into structures called chromosomes.
16. The first step of gene expression, where a gene's DNA is copied into mRNA.
18. The basic unit of DNA and RNA, made of a sugar, a phosphate group, and a nitrogenous base.

1. The second step of gene expression, where the mRNA is used to build a protein at the ribosome.
4. A visual arrangement of all the chromosomes in a cell.
5. The complete set of DNA in an organism.
7. The building blocks of proteins.
9. A molecule similar to DNA that helps carry out the instructions in genes to make proteins.
10. Large molecules made from amino acids that perform many functions in the body.
13. A sequence of three RNA bases that code for one amino acid.
15. A segment of DNA that contains instructions to make a specific protein.
17. base The part of a nucleotide that are either adenine, thymine, cytosine, or guanine.
