( C ) -That the spontaneous generation doesn’t happen
Answer:
Some forms of chromatin modification can be passed on to future generation of cells
Acetylation of histone tails in chromatin allows access to DNA for transcription
DNA is not transcribed when packaged tightly in a condensed form
methylation of histone tails can promote condensation of the chromatin
Explanation:
chromatin modifications that can be passed on includes epigenetic modifications that are heritable changes made to the chromatin structure that does not involve the DNA sequences. Some epigenetic modifications include DNA methylation and Histone modifications. examples of histone modification include acetylation, methylation, phosphorylation, ubiquintylation etc. All these function either in allowing the DNA become more accessible to transcritional factors or vice versa. for exmple, histone tail acetylation encourages unwounding of nucleosomes allowing transcriptional factors to have access to the DNa while histone tails methylation further tightens the nucleosomes promoting condensation of the chromatin.
The seven levels of classification are Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Answer:
Explanation:
Sequencing the human genome is the function of the human genome project with the goal of determining the base pairs/order of DNA nucleotides that make up human genome, and also identifying and mapping all of the genes of the human genome both from the physical level and its functions in molecular medicine. The benefits in this field could allow for better diagnosis of disease, early detection of certain diseases, and gene therapy and control systems for drugs.
Inborn errors of metabolism are rare genetic (inherited) disorders where the body cannot properly digest and turn food into energy through the normal pathway. The disorders are usually caused by mutations in specific enzymes that help in the break down of these foods.
Through the study of the human genome, sequences involved in these mutations giving rise to these disorders are identified and mapped to their variuos locations. This can help in the early diagnosis of the disorders and effective control system for drugs and gene therapy against these disorders.
An organism that makes its own food is a producer.
