How are mitosis and meiosis similar

they both produce new cells(apex)

they both have prophase and metaphase (anaphase)

They both involve duplicating chromosomes.

they both have simular steps.

What happens during interphase

the chromosomes are duplicated.

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.

What is produced by meiosis

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

What does polymerase chain reaction enable scientist to make

Using the Polymerase Chain Reaction, scientists can amplify even the smallest amount of DNA, by constant cycles of separation and replication.

What best describes a gene

A chromosome.

A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.

For apex it's "A piece of a chromosome."

Why did mendel use pea plants in his experiment

They produce many offspring

How are tumor cells different from normal cells

Mitosis is not regulated in tumor cells. This can cause the rapid proliferation of a large number of non-functional cells, whose only actions are to divide into more cells.

Tumor cells multiply too quickly.

What happens directly after prophase

Metaphase

When and why does DNA need to be replicated

DNA is replicated during the S phase of the cell cycle. If DNA is not replicated then the new cell will not have a copy of the DNA. If it does not have a copy of the DNA, then the cell will not be able to function properly.

What are non mendelian trait

A trait with four alleles

What organism that reproduces sexually has a diploid number of 30 how many chromosomes will gamete of this organism have

15

How are meiosis and mitosis different

mitosis only has to do with celluar reproduction

meiosis has to do with sex cells reproducing
Mitosis creates new cells that are used for development, repair, asexual reproduction and growth. Meiosis creates cells in order for organisms to reproduce sexually.

Which best describes the daughter cells produced by mitosis

they are identical to the cell they formed

Which best describes probability

the likelihood that something will happen
