- Question
Where does translation take place in the cell?
Options- A. Nucleus
- B. Mitochondria
- C. Ribosomes
- D. Cytoplasm
- Correct Answer
- Cytoplasm
ExplanationTranslation occurs in the cytoplasm whereas transcription occurs in the nucleus.
Transcription and Translation:
Terms transcription and translation in biology are generally related to the DNA and its properties. Human cells replicate. In order to do that, they have to produce the same constituents for the new cell that is to be made. The only way to do that is by producing proteins.
The proteins are produced in the process that is called protein synthesis. The first step is in the nucleus where a particular gene is being expressed so it enables all protein factors to come and to replicate that part of a chromosome. This is finished when mRNA, the same single-stranded genetic code of a particular gene, is formed. This is transcription.
Right after that, the mRNA enters the cytoplasm through nuclear pores. There, it could be translated into proteins by ribosomes. This process is called translation.

Correct Answer: Uracil
Explanation:
A nitrogenous base, or nitrogen-containing base, is an organic molecule with a nitrogen atom that has the chemical properties of a base. The main biological function of a nitrogenous base is to bond nucleic acids together. A nitrogenous base owes its basic properties to the lone pair of electrons of a nitrogen atom.
In DNA, four bases have been found. They are
1. Adenine (A),
2. Guanine (G),
3. Cytosine (C) and
4. Thymine (T).
The first three of these bases are found in RNA also but the fourth which is Uracil (U) is absent in it.
RNA contains cytosine and uracil as pyrimidine bases while DNA has cytosine and thymine.
Correct Answer: Nucleotides
Explanation:
DNA is a very long chain polymer made up of thousands of repeating units called nucleotides.
Nucleotide Unit is composed of a phosphate group, a pentose sugar, and a nitrogenous base.
The sides of the DNA ladder are made up of alternating deoxyribose sugar -- phosphate group units.
Correct Answer: Yeast belongs to members of the Kingdom Fungi Yeast are single-celled microorganisms that are classified, along with molds and mushrooms in Fungi family Yeasts are evolutionally diverse and are therefore classified into two separate phyla, Ascomycota or sac fungi and Basidiomycota or higher fungi, that together form the subkingdom Dikarya
Correct Answer: Eubacteria
Explanation:
There are two kingdoms of bacteria. They are
1. Eubacteria and
2. Archaea
The members of these two kingdoms appear similar in shape and appearance, even under the extreme magnification of the electron microscope . However, they are very different from each other in a number of molecular and biochemical aspects. It is these differences that have resulted in the microorganisms being grouped into separate kingdoms.
For example, eubacteria contain the rigid, stress-bearing network known as the peptidoglycan . The only exceptions are the bacteria from the genera Mycoplasma and Chlamydia. Archaebacteria do not contain peptidoglycan. Instead, they contain a different structure that is called pseudomurein.
The common bacteria belongs to Eubacteria kingdom.
Correct Answer: prevents chromosomes from separating
Explanation:
A cytoskeleton acts as a frame that gives a cell its shape, protects it to an extent, and helps with cellular motion.
Correct Answer: Heart
Explanation:
Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation (usually veins carry deoxygenated blood to the heart but the pulmonary veins carry oxygenated blood as well).
Correct Answer: Fimbriae
Explanation:
The fimbriae of the uterine tube, also known as fimbriae tubae, are small, fingerlike projections at the end of the fallopian tubes, through which eggs move from the ovaries to the uterus.
The fimbriae are connected to the ovary.
Correct Answer: mitochodria
Explanation:
Cellular repiration takes place in the mitochodria.
There are 3 phases of cellular respiration. They are:
1. Glycolysis (Fermentation),
2. Krebs Cycle, and
3. Electron Transport.
Glycolysis takes place in the cytoplasm. The Krebs cycle and electron transport takes place in the mitochondria.
Correct Answer: Cervicitis
Explanation:
Leukorrhea is a thick, whitish or yellowish vaginal discharge. There are many causes of leukorrhea, the usual one being estrogen imbalance. The amount of discharge may increase due to vaginal infection or STDs, and it may disappear and reappear from time to time. This discharge can keep occurring for years, in which case it becomes more yellow and foul-smelling. It is usually a non-pathological symptom secondary to inflammatory conditions of vagina or cervix.
Correct Answer: Reproductive glands
Explanation:
Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct.
The major glands of the endocrine system include:
pineal gland,
pituitary gland,
pancreas,
ovaries,
testes,
thyroid gland,
parathyroid gland,
hypothalamus and
adrenal glands.
