The answer is 1. A DNA is double stranded with two polynucleotide chain which consists of a phosphate, a sugar and a nitrogen base. Adenine, thymine, guanine, and cytosine are the four types of nitrogen bases.

The answer is 2. A ribosome combines together amino acids by attaching to a part of the mRNA and a complementary amino acid on a tRNA molecule. Synthesis of enzymes would stop because this is usually processed in the ribosomes.

2

The answer is 3. The connection between information from DNA and an amino acid is called genetic code. Bases are the one responsible for the genetic code.

3

The answer is 2. In order for a trait to be expressed, certain genes are paired and are sequenced according to the trait of a certain person which has been transferred from the parents to their offspring.

2

The answer is 3. DNA molecules are made up of proteins. Proteins are the major component of DNA molecules and are therefore responsible for the proper coding of the amino acids.

The answer is 4. A DNA is double stranded with two polynucleotide chain which consists of a phosphate, a sugar and a nitrogen base. Adenine, thymine, guanine, and cytosine are the four types of nitrogen bases.

The connection between an information from DNA and an amino acid is called a genetic code. It is important that the genetic code must separate between the bases for it to equally express the same type of code for replication.

The answer is 2. The nucleus is the organelle wherein it converts DNA into proteins. DNA is replicated, transcribed and translated to proteins in the the nucleus.

The answer is 1. A ribosome combines together amino acids by attaching to a part of the mRNA and a complementary amino acid on a tRNA molecule.

The answer is 1. DNA controls the sequencing of amino acids in proteins. These codes are combined to for different types of proteins for the regulation of different functions in the cell.

The answer is 4. The main function of ribosomes is to make proteins. These proteins are needed in various functions of the cell in order to maintain homeostasis. A ribosome combines together amino acids by attaching to a part of the mRNA and a complementary amino acid on a tRNA molecule.

The answer is 2. A DNA is double stranded with two polynucleotide chain which consists of a phosphate, a sugar and a nitrogen base. Adenine always pairs with thymine and guanine with cytosine.

2

The answer is 1. This is because DNA is used for transcription and translation of DNA into protein. Protein is essential for us living things because it is used in a lot of processes such as enzymes.

The answer is 4. Mutations may be spontaneous wherein the original strand is replaced with another or added with a new one. Another way wherein mutations arise is by inducing a response created by exposure to chemicals or radiation.

4

DNA mutations are mistakes formed in a DNA sequence which can be a result of adding, removing or substituting the original or specified DNA molecule.

The answer is 3. Mutations may be spontaneous wherein the original strand is replaced with another or added with a new one. This type of mutation may be passed on to generations if the gene acquired is carried from the parents to the offspring.

3

The answer is 2. As living organisms reproduce, sex cells are the ones involved during the process of transferring the genetic material from parent to offspring. Sex cells exchange or transfer genetic material from each other.

2

The answer is 4. Mutations may arise is by inducing a response created by exposure to chemicals or radiation that directly affects the chromosome structure. This is called an induced mutation.

The answer is 1. A DNA is double stranded with two polynucleotide chain which consists of a phosphate, a sugar and a nitrogen base. Adenine always pairs with thymine and guanine with cytosine.

1

The answer is 1. The uniqueness of each living organism is based on the DNA bases. No living organism has the same sequence as with another living organism.

1

The answer is 4. Choices 1 and 2 is wrong because sex cells are the ones responsible for the alteration, choice 3 is also wrong because the statement did not include any mutation.

4

The answer is 1. DNA mutations are mistakes formed in a DNA sequence which can be a result of adding, removing or substituting the original or specified DNA molecule.
