If a DNA strand is CGTAGG, what is the complementary DNA strand?

GCATCC
CGTAGG
ATGCTT
TACGAA

Correct Answer

A. GCATCC

Explanation

The complementary DNA strand is formed by pairing each nucleotide with its complementary base. In DNA, adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). Therefore, the complementary DNA strand for CGTAGG would be GCATCC, as each nucleotide is paired with its complementary base.

__________ tissue is a type of animal tissue that covers body surfaces and lines body cavities.

Epithelial
Connective
Muscular
Nervous

Correct Answer

A. Epithelial

Explanation

Epithelial tissue is a type of animal tissue that covers body surfaces and lines body cavities. It serves as a protective barrier against mechanical injury, pathogens, and dehydration. Epithelial tissue is also involved in absorption, secretion, and sensory reception. It is characterized by closely packed cells with little to no extracellular matrix. Connective tissue, on the other hand, supports and connects different structures in the body, while muscular tissue is responsible for movement, and nervous tissue is involved in transmitting and processing signals. Therefore, the correct answer is epithelial tissue.

The metabolic sequence of enzyme-driven reactions by which carbohydrates, proteins, and fatty acids produce carbon dioxide, water, and ATP, is called ______________,

Calvin cycle
Nitrogen cycle
Krebs cycle
Cell cyle

Correct Answer

A. Krebs cycle

Explanation

The Krebs cycle, also known as the citric acid cycle, is a metabolic pathway that occurs in the mitochondria of cells. It is responsible for the breakdown of carbohydrates, proteins, and fatty acids to produce carbon dioxide, water, and ATP (adenosine triphosphate). During this cycle, acetyl-CoA is oxidized to produce NADH and FADH2, which then go on to generate ATP through oxidative phosphorylation. The Krebs cycle is an essential part of cellular respiration and plays a crucial role in energy production.

In the study of genetics Law of Segregation, Law of Independent Assortment, and Law of Dominace are also know as ____________.

Lamarck's Theory of Inheritance of Acquired Characteristics
Mendelian Law of Inheritance
Darwinism
Hershey-Chase Experiment

Correct Answer

A. Mendelian Law of Inheritance

Explanation

The correct answer is Mendelian Law of Inheritance. This is because the three laws mentioned (Law of Segregation, Law of Independent Assortment, and Law of Dominance) were proposed by Gregor Mendel, who is considered the father of modern genetics. These laws describe how traits are inherited from one generation to the next and form the basis of Mendelian genetics. Lamarck's Theory of Inheritance of Acquired Characteristics, Darwinism, and Hershey-Chase Experiment are not directly related to these laws.

Before a genetic message can leave a nucleus of a eukaryotic cell, it must undergo ____________.

Separation
Transcription
Translation
Termination

Correct Answer

A. Transcription

Explanation

Before a genetic message can leave a nucleus of a eukaryotic cell, it must undergo transcription. Transcription is the process by which the genetic information encoded in DNA is copied into a molecule of messenger RNA (mRNA). This mRNA molecule can then leave the nucleus and be used as a template for protein synthesis during translation. Separation, translation, and termination are not directly involved in the process of genetic information leaving the nucleus, making them incorrect options.

The phase of mitosis during which the chromosomes move toward separate poles of the cell is _____.

Telophase
Anaphase
Metaphase
Cytokinesis

Correct Answer

A. Anaphase

Explanation

During anaphase, the chromosomes move towards separate poles of the cell. This is accomplished by the spindle fibers pulling the sister chromatids apart, causing them to migrate towards opposite ends of the cell. This phase is characterized by the elongation of the cell and the movement of the chromosomes, ultimately leading to the formation of two distinct sets of chromosomes at opposite poles of the cell.

Which of the following is not a method of asexual reproduction in plants?

Vegetative propagation
Budding
Pollination
Spore formation

Correct Answer

A. Pollination

Explanation

Pollination is not a method of asexual reproduction in plants because it involves the transfer of pollen from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower, leading to sexual reproduction and the formation of seeds. Asexual reproduction, on the other hand, does not involve the fusion of male and female gametes and produces offspring that are genetically identical to the parent plant. Vegetative propagation, budding, and spore formation are all methods of asexual reproduction in plants where new individuals are produced from vegetative parts, buds, or spores, respectively.

If an organism is multicellular, does not carry on photosynthesis, absorbs nutrients from the environment, and is composed of eukaryotic cells with cell walls, it can be classified under which of the following kingdoms?

Animal
Bacteria
Plant
Fungi

Correct Answer

A. Fungi

Explanation

The given characteristics of the organism, such as being multicellular, not carrying out photosynthesis, absorbing nutrients from the environment, and having eukaryotic cells with cell walls, align with the characteristics of fungi. Fungi are organisms that obtain nutrients through absorption and have eukaryotic cells with cell walls. Therefore, based on these characteristics, the organism can be classified under the kingdom Fungi.

All of the following are protists except __________.

Basidiomycota
Chlorophyta
Ciliophora
Dinoflagellata

Correct Answer

A. Basidiomycota

Explanation

Basidiomycota is not a protist but a fungal group. Protists are a diverse group of eukaryotic microorganisms that do not fit into the categories of plants, animals, or fungi. Chlorophyta, ciliophora, and dinoflagellata are all examples of protists.
