What is a mutagen
an environmental angent that changes DNA. APEX
How are genes and proteins related
genes contain the code to make proteins
proteins are made from instructions in genes
What is gel electrophoresis used for
used to separate macromolecules, either nucleic acids or
proteins, on the basis of size, electric charge, and other physical
properties.
Separating strands of DNA
What could be a good effect of a mutation
More varity in a population
Which describes how mRNA is used by a cell
it is used to transfer genetic information
What describes a DNA mutation
changes in the DNA sequence
Which of the following determines the specificity of a DNA probe
What should scientist do to find gene that produces protein after he located all the mrna produced by liver and cdna if he wants to artifically produce protein that is produced in liver of frogs
The scientist should mix the cDNA with the liver DNA.
A plant survives in a tropical rain forest when placed in a temperature forest it dies within a year what is most likely characteristic of the plant
That plant needs stable weather.
Why does a detetion mutation usually cause more defect during protein synthesis than point mutation
Mutation usually causes the entire base sequence to defect. This
usually happens during the protein synthesis.
Which amino acid chain will be formed by the codons shown below ACU CCA UCG
Asn- Lys- Asp (Apex 2021)
The results of gel electrophoresis are shown below with four different strands of DNA labeled. Which strand of DNA is the shortest
Answer this q The results of gel electrophoresis are shown below, with four different strands of DNA labeled.
Which strand of DNA is the shortest? uestion…
In an experiment a scientist makes a radioactively labeled probe using human DNA she then discovers that the probe hybridizes to a small segment of DNA isolated from plant what can she conclude from h
The plant might have a gene that is similar to a human gene

What is a possible effect of an error during transcription apex
The wrong amino acid will be used
