This process is known also as protein synthesis. It is the process that converts the mRNA code into an amino acid sequence.
transcription
replication
translation
mutation
This process is used to make an exact copy of DNA. It occurs in the nucleus of a cell. It occurs during interphase (before mitosis or meiosis).

This type of chromosomal abnormality occurs when part of one chromosome breaks off and is added to a different chromosome.
Translocation
Inversion
Deletion
Duplication
X-rays, ultraviolet light, and radioactive substances that can change the chemical nature of DNA are referred to as this. They are defined as any agent that can cause a change in DNA.

Match the following jobs to the correct form of RNA
mRNA
brings code from DNA
tRNA
carries an amino acid
rRNA
combines w/ protein to form a ribosome
Match the shape to the correct term
mRNA
single strand
tRNA
"t" or cloverleaf
rRNA
lumpy glob
DNA
double helix
Match the following to the correct area of the cell
nucleus
replication and transcription take place; DNA found here
cytoplasm
ribosomes found here; mRNA attaches to ribosomes, tRNA and amino acids join
ribosome
mRNA molecule is read; codon & anticodon line up
A (a) mutation occurs when a single letter (base) in changed in the sequence. They can be less harmful as they disrupt a single codon. A (b) mutation occurs when a letter (base) is added or removed. It shifts the reading of codons by one base.
Match the following chromosomal alternations
deletion
a part of the chromosome is left out
insertion
chromatid breaks off & attaches to a sister chromatid; duplication of genes
inversion
chromsome breaks off & reattaches backwards
translocation
chromosome breaks off & is added to a different chromosome
This is a chart of chromosome pairs
