If epigenetic modifications are passed on during meiosis, how can a fertilizer egg develop all of...
Homework Answers
Though, epigenetic modification has been performed.
In fertilized eggs there are many maternal gene which is present in the cytoplasm of the egg .
When zygote is formed this factors will control various other proteins level by regulating translation of transcription or controlling some other protein's post transcription regulation.
Like in drosophila, bicoid in anterior portion inhibit caudal and stimulate the synthesis of Hunchback protein this two effects will help the anterior portion to be anterior.
Thank you

describe how the Methyl-directed mismatch repair system in E. coli which DNA strand is the correct strand and determines which DNA strand has the mutation. describe how DNA methylation is heritable during replication how epigenetic modifications are involved in genomic imprinting, X-inactivation, and regulation of tissue/cell specific gene expression (including the general roles of TrxG and PcG group proteins). ***Are these heritable during mitosis or meiosis? Are these reversible? Can you support your answer?

In Drosophila, nondisjunction during meiosis in the parent can result in flies with abnormal numbers of sex chromosomes. Flies with a single X and no Y are male, and those with XXY are female. Which of the following events could not give rise to a male with a single X in Drosophila? Nondisjunction at meiosis II in the female parent Nondisjunction at meiosis I in the male parent Nondisjunction at meiosis I in the female parent All of these CAN...

Barbara is a research biologist for Green Carpet Lawns. She is studying the effects of fertilizer type, temperature at time of application, and water treatment after application. She has three fertilizer types, two temperature zones, and five water treatments to test. Determine the number of different lawn plots she needs in order to test each fertilizer type, temperature range, and water treatment configuration.
