<h2>Epigenetic modification </h2>
Explanation:
A methyl group bound to DNA inhibits transcription of a gene describes an epigenetic modification
Epigenetic modifications include: histone modifications and methylation
Methylation is the main cause of gene silencing for example methylation at lysine residue of histone protein, H4 leads to gene repression
Small silencing RNA molecules are of two types: micro RNA (miRNA) and small interfering RNA (siRNA)
miRNA directs degradation of target mRNA when makes perfect complementary while suppress mRNA translation when makes partial or imperfect complementary
siRNA primarily mediates degradation of target RNA
Answer:
Drooping the sticks on the table and transcribing the letters on the sides facing up follow Mendel's law of segregation by showing the segregation determining which alleles end up in the gamete.
Explanation:
- The Mendel's law of segregation states that the allele pairs always separate and segregate at gamete formation process and they randomly unite at the fertilization.
- When fertilization process is carried, the new organism developed has multiple factors for each trait, one from each parent.
- So the bending or drooping of the sticks and transcribing letter follows that law proposed by Mendel in 1860s.
- This law is also commonly known as the purity of gametes.
