What is a mutagen

an environmental angent that changes DNA. APEX

What is the purpose of transcription

Transcription is the process in which part of the nucleotide sequence of DNA is copied into a complementary sequence RNA. Transcription is helps to preserve the spoken way that allows it to be easily stored and examined in the future. Transcription allows a piece to be referenced in the future.

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 is nuclear transfer used for

Creating clones

Which is used to copy DNA for DNA fingerprinting

Polymerase chain reaction

Which describes how mRNA is used by a cell

it is used to transfer genetic information

Which protects the DNA of a virus

Capsid

How can a mutation in a gene affect the trait that an organism has

The Gene will code for a different protein than it should

Which is a type of Virus out of Bacteria Capsid Bateriophage and Pilus

Which best describes how common cold spread in the human body

Iceberg concept of viral infection best describes how common cold spreads in the human body.

What happens right before transaction begins

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
