Genetics and DNA

Front

What is a dominant trait?

Back

A dominant trait is a genetic characteristic that is expressed in the phenotype even when only one copy of the allele is present. For example, in pea plants, yellow seed color is a dominant trait.

Front

What are the monomers of DNA?

Back

The monomers of DNA are nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the organelles where protein synthesis occurs, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides twisted around each other, held together by hydrogen bonds between complementary bases.

Front

What is the role of the nucleus in a cell?

Back

The nucleus is the organelle that contains the cell's genetic material (DNA) and controls cellular activities by regulating gene expression.

Front

What is a recessive trait?

Back

A recessive trait is a genetic characteristic that is expressed in the phenotype only when two copies of the allele are present. For example, green seed color in pea plants is a recessive trait.

Front

What are alleles?

Back

Alleles are different versions of a gene that can exist at a specific locus on a chromosome, contributing to genetic variation.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is zero.

Front

What is the slope of a linear equation?

Back

The slope of a linear equation represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is the process of transcription in genetics?

Back

Transcription is the process by which the information in a gene is copied into messenger RNA (mRNA) from DNA.
