Archegoniate - Unifying features of archegoniates, Transition to land habit, Alternation of generations

What is Archegoniate? Archegoniate is the group of plants in which the female sex organ called archegonium is present. It is a multicellular flask-shaped structure that is formed during the gametophyte phase, and it is the place where the ovum is produced and retained. It is the outer jacket layer of sterile cells that protect … Read more

These organisms are named after David Bruce and are placed under the family … Read more

Okazaki Fragments – Formation, Enzymes, Importance

Okazaki Fragments - Definition, Discovery, Formation, Enzymes, Importance

Okazaki fragment is the short segment of DNA that is synthesized on the lagging strand during DNA replication. It is formed because the DNA polymerase can extend the new strand only in the 5’–3’ direction, so the strand that is oriented in the 3’–5’ direction is produced in a discontinuous manner. It is initiated by … Read more

Pureline Selection – Procedure, Applications, Advantages, Disadvantages

Pureline Selection

Pureline selection is a method used in plant breeding where plants are chosen from a single self-pollinated variety to create a population that is genetically uniform. It was first introduced by Johannsen (1903) while working with beans (Phaseolus vulgaris). The method based on assumption that variation seen in self-pollinated crops is mostly due to environment … Read more

Post-transcriptional Modification – Definition, Types, Process, Importance

Post-transcriptional modification

Post-transcriptional modification is a set of biological processes common to most eukaryotic cells by which an primary RNA transcript is chemically altered following transcription from a gene to produce a mature, functional RNA molecule that can then leave the nucleus and perform any of a variety of different functions in the cell.

Difference Between Analytical Balance and Triple Beam Balance

Difference Between Analytical Balance and Triple Beam Balance

What is Analytical balance? What is Triple beam balance? Difference Between Analytical Balance Vs Triple Beam Balance 1. Precision – Analytical balance gives very high precision (up to 0.0001 g) while triple beam balance only measure till 0.01 g, so less sensitive comparatively. 2. Power Source – Analytical balance mostly works on electric / electronic … Read more
