5.

What are the molecular scissors in rDNA technology .what are they used for in rDNA technology

Answer»

(a) RESTRICTION endonucleases are called molecular scissors as they cut the DNA segments at particular locations. Example: EcoRI.

(b) Restriction enzymes cut the DNA strands some distance away from the centre of the palindromic sites, but between the same two bases on the opposite strands. This leaves single stranded portions with OVERHANGING STRETCHES called STICKY ends on each STRAND as they form hydrogen bonds with their complementary cut counterparts. This stickiness at the ends of DNA fragments facilitates the action of enzyme DNA ligase

How can an alien piece of DNA made to multiply in a host cell

Answer»

In a chromosome there is a specific DNAsequence called the ORIGIN of replication, which is responsible for initiating replication. ... Thus, an alien DNA is linked with the origin of replication, so that, this alien PIECE of DNA can replicate and MULTIPLY itself in the HOST organism

8.

How does the stickiness of cut ends of DNA help

Answer»

'sticky' end is produced when the restriction enzyme cuts at one end of the SEQUENCE, between two bases on the same STRAND, then cuts on the opposite end of the COMPLEMENTARY strand. This willproduce two ends of DNA that will have some NUCLEOTIDES without any complementary bases

Application of abscissic acid in agri and horticulture

Answer»

Here is ur and dear
Drought stress is a major cause of postproduction decline in bedding plants. The plant hormone abscisic acid (ABA) regulates drought stress responses by mediating stomatal closure, THEREBY reducing transpirational WATER loss. Exogenous ABA applications delay wilting and allow plants to survive short PERIODS of severe drought. The effectiveness of the ABA biochemical, s-ABA (ConTego™; Valent BioSciences Corp., Libertyville, IL), at delaying wilting and extending shelf life during drought stress was evaluated in six bedding plant species. Spray and drench applications of 0 or 500 mg·L−1 s-ABA were applied to Impatiens walleriana(impatiens), Pelargonium ×hortorum (seed geranium), Petunia ×hybrida (petunia), Tagetes patula (marigold), Salvia splendens (salvia), and Viola ×wittrockiana(pansy). Water was subsequently withheld and wilting symptoms were compared between treated and control plants. s-ABA applications delayed wilting in all crops by 1.7 to 4.3 days. Leaf chlorosis was observed after s-ABA application in drought-stressed seed geraniums, marigolds, and pansies. In seed geraniums and marigolds, the drought stress itself resulted in leaf chlorosis that was EQUIVALENT to or more severe than the s-ABA application alone. In pansies, s-ABA applications induced leaf chlorosis that was more severe than the drought treatment. Overall, s-ABA was consistently effective at reducing water loss and extending shelf life for all species treated. Applications of s-ABA to bedding plants before shipping and retailing would allow plants to maintain marketability even under severe drought stress conditions.

Hello,,, details explanation of Human eye... quality answer required☺ hope u will give me quality answer... Don't spam

Answer»

Hey Mate !!

Thanks for the question.

The human EYE is one of the most important sense organs. It enables us to see the object and colours AROUND us.

Components of Human Eye :

⏩ The eye ball is nearly spherical in shape.

⏩ The front portion is more sharply curved and is covered by transparent protective MEMBRANE called the " Cornea ".

⏩ Beside the Cornea, there is place filled with a liquid called aqueous humour and behind this a crystalline lens which is RESPONSIBLE for the image formation.

⏩ Between the aqueous humour and the lens we have a muscular diaphragm called " Iris". Which has small hole in it called " Pupil".

⏩ Iris is the coloured part that we see in an eye.

⏩ The Ciliary muscle to which eye lens is attached helps the eye lens to change its focal length by changing the radii of curvature of the eye lens. V

Answer»

Heyyy !!!

Here is your answer -
____________________________________
MERISTEMATIC TISSUE -

It's a simple tissue which is composed of group of similar and immature cells (meristematic cells) which can divide to form new cells.

Breifly Discription -

Characteristics of meristematic tissue -
✓ They have ABILITY to grow and divide.
✓ They have small and immature cells.
✓ Intercellular spaces are absent.
✓ may be rounded, oval or polygonal shaped.
✓ Cells have dense cytoplasm and CONSPICUOUS nucleus.
✓ Endoplasmic Reticulum are small.
✓ Mitochondria posses simple structure.
✓ Instead of Plastid, proplastids are present.
✓ Rate of Respiration is very high.

Types of Meristematic tissue (on the basis of positions)

1. Apical Meristem - Present on the tip of stem and roots. They are responsible for growth of length of plant.

2. Intercalary Meristem - Present at intercalary position (at nodes). They help in elongation of the organs.

3. Lateral Meristem - They are found on the lateral side. They are responsible for increment in thickness.
____________________________________
PERMANENT TISSUE -

They are of three types -
Simple Permanent Tissue.
Complex Permanent Tissue.
Special Permanent Tissue.
____________________________________
SIMPLE PERMANENT TISSUE -

Group of similar permanent cells having same function are known as Simple Permanent Tissue.

Explain sexual reproduction in human

Answer»

Sexual reproduction is a form of reproduction where two gametes FUSE together. Each gamete contains half the number of chromosomes of normal cells. They are created by a specialized type of cell division, which only occurs in eukaryotic cells, known as meiosis. The two gametes fuse during fertilization to produce DNA replication and the creation of a single-celled zygote which includes genetic material from both gametes. In a process called genetic recombination, genetic material (DNA) JOINS up so that homologous chromosome sequences are aligned with each other, and this is followed by exchange of genetic information. Two rounds of cell division then produce four daughter cells with half the number of chromosomes from each original parent cell, and the same number of chromosomes as both parents. For instance, in HUMAN reproduction each human cell contains 46 chromosomes in 23 pairs. Meiosis in the parents' gonads produce gamete cells which only contain 23 chromosomes each. When the gametes are COMBINED via sexual intercourse to form a fertilized egg, the resulting child will have 23 chromosomes from each parent genetically recombined into 23 chromosome pairs or 46 TOTAL.
