Back

1 allele.

Front

TRUE or FALSE: Transcription happens before translation in protein synthesis.

Back

True.

Front

How many cells are created at the end of MEIOSIS 2?

Back

4 cells.

Front

What are homologous chromosomes?

Back

A pair of chromosomes, one inherited from each parent, that are the same size, stain the same, and carry the code for the same traits.

Front

What is transcription in protein synthesis?

Back

The process of copying a segment of DNA into mRNA.

Front

What is translation in protein synthesis?

Back

The process of converting mRNA into a sequence of amino acids to form a protein.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What are sister chromatids?

Back

Identical copies of a chromosome, connected by a centromere, formed during DNA replication.

Front

What is a karyotype?

Back

A visual representation of an individual's chromosomes, arranged in pairs.

Front

What is the function of a centromere?

Back

The region of a chromosome where sister chromatids are joined and where spindle fibers attach during cell division.
