What is meant by translocation?
- The term ″translocation″ refers to a shift of location.
- When a portion of a chromosome is transferred to another chromosome, it is referred to as chromosomal transfer.
- Chromosomes are structures that contain genes, which are the building blocks of our genetic inheritance.
What is the difference between translation and translocation?
Jan 22, 2020 · What is meant by translocation in biology? translocation . In genetics, the movement of a portion of one chromosome to another; in protein synthesis, the transfer of the newly elongated peptidyl-tRNA from the amino acyl site to the peptide site of a ribosome; in cell biology , the movement of a molecule across a barrier or between cytosol and membrane …
What type of mutation is translocation?
Dec 07, 2020 · Translocation is a biological mechanism involving the transfer of water and other soluble nutrients from one part of the plant to another through the xylem and phloem, which occurs in all plants. Transport of the soluble photosynthesis product or food from the leaves to other plant parts is referred to as translocation.
What is meant by translocation?
Mar 21, 2022 · From the source to the sink: Translocation is defined as the transportation of organic molecules from where they are produced at their source to where they are required at their sink (source to sink). It is a dynamic mechanism that may be employed to transfer phloem either up or down the plant’s vascular system.
What is a translocation process?
Nov 15, 2021 · Translocation is defined as the transport of food and water from leaves to all the part of plant including root. Translocation is very essential in plants because food is synthesized in leaves only and this product is needed to be reached to all the parts of plant. Translocation occurs through phloem.
What is translocation called?
Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.
What is translocation short answer?
Answer: Translocation is a biological mechanism involving the transfer of water and other soluble nutrients from one part of the plant to another through the xylem and phloem, which occurs in all plants.
What is meant by translocation class 10?
Translocation is the process by which plants deliver minerals, plant growth hormones, water, and organic substance over long distances throughout the plants (from leaves to other parts).
What is translocation class 7th?
The process of transporting prepared food from the leaves to other parts of the plant through phloem cells is known as translocation.
What is translocation in plants Class 11?
It is the movement of substance in bulk from one point to another as a result of pressure difference between two points. The bulk movement of substances through the conducting or vascular tissue of plants is called Translocation.Oct 8, 2018
What is the definition of transcription translation and translocation?
Transcription is the process of production of RNA (Ribo Nucleic Acid) from DNA (Deoxy ribo Nucleic Acid). Translation is the process of formation of protein from RNA. Translocation is the movement of materials in plants from the leaves to other parts of the plant.Jun 4, 2020
What does a mutagen cause?
Mutagens. Mutagens are chemical compounds or forms of radiation (such as ultraviolet (UV) light or X-rays) that cause irreversible and heritable changes (mutations) in the cellular genetic material, deoxyribonucleic acid (DNA).
What is a ribozyme?
A ribozyme is a ribonucleic acid (RNA) enzyme that catalyzes a chemical reaction. The ribozyme catalyses specific reactions in a similar way to that of protein enzymes. Also called catalytic RNA, ribozymes are found in the ribosome where they join amino acids together to form protein chains.
What is the process called that converts the genetic?
Transcription is the process by which a DNA template is used for the manufacture of several different types of RNA.
What is true about tRNA?
Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. When a tRNA recognizes and binds to its corresponding codon in the ribosome, the tRNA transfers the appropriate amino acid to the end of the growing amino acid chain.
In what direction are nucleic acids assembled?
Nucleic Acid Strands Grow in the 5′ → 3′ Direction All RNA and DNA synthesis, both cellular and viral, proceeds in the same chemical direction: from the 5′ (phosphate) end to the 3′ (hydroxyl) end (see Figure 4-13). Nucleic acid chains are assembled from 5′ triphosphates of ribonucleosides or deoxyribonucleosides.
What is a ribozyme quizlet?
What is a ribozyme? A) an enzyme that uses RNA as a substrate. B) an RNA with enzymatic activity. C) an enzyme that catalyzes the association between the large and small ribosomal subunits. D) an enzyme that synthesizes RNA as part of the transcription process.
Does a codon extend from one end of a tRNA molecule?
It extends from one end of a tRNA molecule. It is the basic unit of the genetic code. It consists of three nucleotides. It never codes for more than one amino acid.
What is the function of a phloem?
Phloem. The phloem moves food substances that the plant has produced by photosynthesis to where they are needed for processes such as: growing parts of the plant for immediate use. storage organs such as bulbs and tubers. developing seeds.
What is the energy that plants use to produce glucose?
During photosynthesis, plants produce glucose from simple inorganic molecules - carbon dioxide and water - using light energy. Some of the glucose produced by photosynthesis is used for respiration. This releases energy for the seven life processes.
Where does the small ribosomal subunit bind to?
The small ribosomal subunit binds to a sequence in the mRNA just upstream of the start codon. The small ribosomal subunit binds to the Shine-Dalgarno sequence, which is about 6 nucleotides upstream from the start codon.
How does RNA polymerase transcribe DNA?
transcription. The enzyme RNA polymerase transcribes DNA by applying the base-pairing rules. It's like DNA replication, but strand of DNA as a template. (1) base U (not T) pairs with base A, (2) the DNA isn't all transcribed at once, and (3) each act of transcription uses only one.
