Front

What does it mean to be homozygous in genetics?

Back

Having two identical alleles (also known as purebred).

Front

What is the amino acid sequence for the mRNA code AUGCCAGUAUGA?

Front

What are stem cells?

Back

Undifferentiated cells that can develop into any type of cell.

Front

During which part of the cell cycle is DNA copied?

Back

S phase.

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

Define phenotype.

Back

The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic constitution of an organism, while phenotype is the expression of that genotype in the organism's traits.

Front

What is codominance in genetics?

Back

A situation in which both alleles in a heterozygous organism contribute to the phenotype.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis, where mRNA is translated into amino acid sequences.
