Year 10 Biology

What are the two basic functions of DNA?

• carrying genetic information for inheritance an coding for amino acids to produce proteins

• Storing genetic information and transmitting genetic information
• Encoding genetic information and decoding genetic information
• Creating genetic information and destroying genetic information

What are chromosones?

• Chromosomes are thread-like structures made of DNA and proteins that carry genetic information in the form of genes

• Chromosomes are responsible for producing energy in cells.
• Chromosomes are only found in plant cells.
• Chromosomes are structures made of carbohydrates and lipids.

What is the genetic code?

• The genetic code is a type of barcode used in DNA sequencing.
• The genetic code refers to the process of cloning genes in a laboratory setting.
• The genetic code is a term used to describe the physical appearance of an organism.
• The base sequence of each gene which contain information for one characteristic.

What is a protein?

• Proteins are made up of nucleic acids
• Proteins are not essential for body functions
• Proteins are simple sugars
• Proteins are large biomolecules consisting of one or more long chains of amino acid residues, that control the characteristics of the body.

What is an allele?

• A type of protein found in cells.
• A type of cell division.
• Different forms of the same gene.

• A unit of heredity that is transferred from a parent to offspring.

What is a gene?

• A gene is a section of DNA that carries the genetic code for a particular protein.

• A gene is a type of protein found in plants
• A gene is a type of cell in the human body
• A gene is a type of virus that affects DNA

What is a nucleotide and what does it consist of?

• A nucleotide consists of a sugar molecule, a lipid, and a nitrogenous base
• A nucleotide is the information of the cells consists of a protein molecule, a phosphate group, and a nitrogenous base

• A nucleotide is the structural unit and consists of a sugar molecule, a phosphate group, and a nitrogenous base.

• A nucleotide is the nucleous consists of a sugar molecule, a phosphate group, and a lipid

What is homozygous?

• An individual having two identical alleles for a particular gene.
• An individual having no alleles for a particular gene.
• An individual having two different alleles for a particular gene.
• An individual having one dominant and one recessive allele for a particular gene.

What is heterozygous?

• Having no alleles for a particular gene.
• Being homozygous for a particular gene.
• Having two different alleles for a particular gene.
• Having two identical alleles for a particular gene.

What is phenotype?

• Phenotype is the observable physical or biochemical characteristics of an organism.
• Phenotype is the study of animal behavior.
• Phenotype is the genetic material of an organism.
• Phenotype is the process of photosynthesis in plants.
