What is Metaphase in cell division?

Back

Metaphase is the stage of cell division where chromosomes align in the middle of the cell before being separated into daughter cells.

What signals the ribosome to start translating mRNA?

Back

A codon signals the ribosome to begin translating mRNA into a new amino acid sequence.

Front

What is the chromosome number of daughter cells produced by Meiosis?

Back

The chromosome number of daughter cells produced by Meiosis is haploid.

Front

What determines the type of specialized cell a stem cell will become?

Back

The genes that are expressed determine the type of specialized cell a stem cell will become.

Front

What phase of the cell cycle involves cell growth and preparation for DNA replication?

Back

The G1 phase of the cell cycle involves cell growth and preparation for DNA replication.

Front

Define protein synthesis.

Back

Protein synthesis is the process by which cells generate new proteins, involving transcription of DNA to mRNA and translation of mRNA to amino acids.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells contain two complete sets of chromosomes (one from each parent), while haploid cells contain only one set of chromosomes.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures that facilitate the translation of mRNA into proteins.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two copies of each chromosome.
