MUTATIONS
The changes in the genetic makeup of a cell are Called mutations. The mutations alter the structure of chromosomes. Sometimes, a point mutation occurs in a gamete, or in a…
Control of Gene Expression in Eukaryotes
The expression of gene can be controlled at different levels in the eukaryotes Transcriptional Control of Gene Expression The RNA synthesis depends on RNA polymerase enzymes. Numerous proteins called transcription…

saadia3. THE FORAMINIFERA oraminiferans are commonly called for:ans. They are primarily- a marine group of amoebae. Foraminiferans possess reticulopodia They secrete a test of calcium carbonate. The foramini ferans grow…
GENES IN ACTION
A sequence of bases in DNA that .codes for the synthesis of One polypeptide is called gene. The genes must transmit their information from the nucleus to the cytoplasm. Therefore,…
THE AMOEBOID PROTOZOA
THE AMOEBOID PROTOZOA Members Of the amoebozoans are the amoebae (sing.. amoeba). They form temporary cell extensions called pseudopodia.There are different forms of pseudopodia. 1. Lobopodia (mean little foot): They…
