Why do chromosomes get shorter during replication? Why is it necessary to reduce the chromosome number of gametes (egg and sperm), but not other cells of an organism? Describe the significance of meiosis. Describe chromosomes and alleles. ...
How does the process of meiosis contribute to the genetic variation of Sordaria? (a) Differentiate between mitosis and meiosis. (b) Explain the significance of meiosis. Define Meiosis. Explain in detail the difference between mitosis and meiosis Describe Meiosis...
2. Such divergences between males and females are the results of sexual selection for traits that influence individual fitness during the evolution process3. Selective pressure may lead to sexual antagonism, in which traits are beneficial to one sex but harmful to another4,...
Explain how the lagging strand is synthesized even though DNA polymerase can add nucleotides only to the 3' end. Describe the significance of Okazaki fragments Explain the role of RNA polymerase in transcription. Explain how you could use the nucleic acid sequence of RNA fo...
WAP (Whey Acidic Protein)-type 'four-disulfide core', extracellular link domain, dual specificity phosphatase catalytic domain, KR domain, and tyrosine phosphatase family domain were found increased (Supplementary TableS2). The significance of the domains with increased number will be discussed below....

Studies of one family - two children and a mother - demonstrated that the event occurred during mitosis or cell division, a significant finding that further confirms the significance of the event. The researchers noted that finding this mitotic rearrangement of the gene in the mother, who did no...
Describe the structure of a nucleotide. What is its significance in relation to DNA and RNA? Draw the DNA structure and explain why the DNA strands are antiparallel. Describe the structure of DNA, nucleotides and N-bases. Explain the function of all molecules involved i...
Compare the effects of HCl on protein digestion by pepsin and on starch digestion by salivary amylase. Explain the physiological significance of these effects. Explain transduction? Define the following medical term: Anteflexion Briefly Define: Etiology ...
The mechanism of human immunodeficiency virus 1 (HIV-1) nuclear entry, required for productive infection, is not fully understood. Here, we report that in HeLa cells and activated CD4+ T cells infected with HIV-1 pseudotyped with VSV-G and native Env pro
