What is the shape of the DNA called?
-
Double spiral
-
Circular
-
Spiral
-
Double helix
Correct Answer
A. Double helixExplanation
The shape of DNA is called a double helix. This refers to the twisted ladder-like structure formed by two strands of nucleotides that are connected by hydrogen bonds. The double helix shape allows for the compact storage of genetic information and provides stability to the DNA molecule.Rate this question:

How many types of RNA do we have?
-
1
-
2
-
3
-
4
Correct Answer
A. 3Explanation
There are three types of RNA: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). mRNA carries the genetic information from DNA to the ribosomes, where it is used as a template for protein synthesis. tRNA brings amino acids to the ribosomes during protein synthesis. rRNA is a structural component of ribosomes, which are responsible for protein synthesis.Rate this question:

Which one is not found in the structure of the DNA?
-
Phosphate
-
Uracil
-
Thymine
-
None of these
Correct Answer
A. UracilExplanation
Uracil is not found in the structure of DNA. DNA is composed of four nitrogenous bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Uracil (U) is a nitrogenous base that is found in RNA instead of DNA. In RNA, uracil replaces thymine. Therefore, the correct answer is Uracil.Rate this question:

RNA does not leave the Nucleus, but DNA does.
-
True
-
False
Correct Answer
A. FalseExplanation
This statement is incorrect. DNA does not leave the nucleus, while RNA does. DNA is the genetic material that is stored in the nucleus of a cell and is responsible for storing and transmitting genetic information. RNA, on the other hand, is synthesized from DNA and carries the genetic information from the nucleus to the cytoplasm, where it is used to produce proteins. Therefore, the correct answer is false.Rate this question:

What are the building blocks of protein called?
-
Polypeptide
-
Lipase
-
Amino acid
-
Enzymes
Correct Answer
A. Amino acidExplanation
Amino acids are the building blocks of proteins. Proteins are composed of long chains of amino acids that are linked together by peptide bonds. Each amino acid has a specific structure and unique side chain, which determines its properties and function. When these amino acids join together, they form polypeptides, which can then fold into specific three-dimensional structures to create functional proteins. Lipase is an enzyme that breaks down lipids, while enzymes are proteins that catalyze chemical reactions in the body. However, neither lipase nor enzymes are the primary building blocks of proteins.Rate this question:

DNA is found in the _________ of a cell.
-
Lipase
-
Ribosome
-
Both A & B
-
Nucleus
Correct Answer
A. NucleusExplanation
DNA is found in the nucleus of a cell. The nucleus is the control center of the cell and contains the genetic material, including DNA. Lipase is an enzyme involved in the breakdown of lipids, and ribosomes are involved in protein synthesis. While both lipase and ribosomes are important components of cells, they do not contain DNA. Therefore, the correct answer is nucleus.Rate this question:

Which one is not part of the Nucleus?
-
Ribosomes
-
Nuclear membrane
-
Nucleolus
-
Chromatin network
Correct Answer
A. RibosomesExplanation
Ribosomes are not part of the nucleus. Ribosomes are small, spherical organelles found in the cytoplasm of cells. They are responsible for protein synthesis and are involved in translating the genetic information stored in the DNA. While the nucleus contains the genetic material of the cell and is surrounded by a nuclear membrane, nucleolus, and chromatin network, ribosomes are located outside of the nucleus in the cytoplasm.Rate this question:

Carries genetic material can be used for paternity tests and biotechnology crime investigations.
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is true because genetic material, such as DNA, can be used in paternity tests to determine biological relationships between individuals. It can also be used in biotechnology crime investigations to identify suspects or link them to a crime scene through DNA evidence. Therefore, genetic material is valuable in both paternity tests and biotechnology crime investigations.Rate this question:

How many codons are required to specify five amino acids?
-
2
-
3
-
5
-
7
Correct Answer
A. 5Explanation
To specify an amino acid, three nucleotides called codons are required. Since we need to specify five amino acids, we would need a total of 5 codons. Each codon consists of three nucleotides, so 5 codons (5 x 3 = 15 nucleotides) would be needed to specify five amino acids. Therefore, the correct answer is 5.Rate this question:
