What happens during interphase

the chromosomes are duplicated.

Where does DNA transcription take place

In the Nucleus of the Cell.

What is produced by meiosis

Reproductive cells-- egg or sperm cells--or produced by meiosis.

What happens during translation

When the mRNA is used to make the polypeptide coded for.

The force that is used to separate DNA fragments on a gel in the process of electrophoresis is what

Gel Electrophoresis

Explain how two atoms of the same element can have different number of neutrons

These atoms are isotopes of the same element.

Which is true about a daughter cell produced by mitosis

it can function independently

What happens directly after prophase

Metaphase

Which of the following steps happens last during transcription

RNA polymerase reaches the end of a gene.

How are the lysogenic and lysogenic and lytic cycles different

: During the lysogenic cycle, the cell is not killed.

Which of the following explains why a probe will hybridize to a target gene but not to any unrelated genes

Complementary base pairing occurs only between the probe and the target gene.

Which of the following is a cause of a DNA mutation

DNA exposure to high energy radiation

A greater amount of DNA damage occurs when a living organism is exposed to a greater amount of a radioactive isotope how might this affect the number of mutations acquired by the organism

More mutations will be acquired, leading to more phenotypic changes.

What possible effect of an error during transcription

A possible effect of an error during transcription can be a mutation. The mutation can cause a change in a protein. This change can be beneficial or damaging.

Best describes the structure of a DNA molecule

A double helix of two strands of DNA linked together with sugar-phosphate backbones with bases on the inside.

What is true about gel electrophoresis

The heaviest molecules are at the top of the sheet in gel electrophoresis (if it is SDS-PAGE electrophoresis).

What forms a base pair with adenine

Thymine in dna, and uracil in rna.

Which of the following processes takes place in the ribosomes of a cell

translation only

What best describes a rhino virus

A virus that causes the common cold. APEX

What molecule consists of a string of nucleotides made up of a nitrogenous base deoxyribose and a phosphate group

This is the deoxyribonucleic acid (DNA).
