Helicase "unzips" the two strands of DNA. During DNA replication.
Answer:
It will decrease in size and it will pinch to surround anything entering the cell.
Answer:
internal receptor binding
Explanation:
This is because steroid hormones are lipids by nature (usually composed of cholesterol) so they are hydrophobic. This means that steroid hormones can easy pass through the membrane and bind to their internal receptors.
Internal receptors also known as intracellular receptors have DNA binding domain and when hormones bind to them DNA-binding site becomes exposed. Hormone-receptor complex gets into the nucleus and binds to regulatory regions of the DNA. Cellular response is gene expression.
Answer:
1/4.
Explanation:
The Mendel is known as father of genetics. He explained the concept of dominance, law of segregation and law of independent assortment while working on the pea plant.
The cross between the heterozygous seed color (Ss × Ss), result in the 3/4 dominant phenotype ( SS, Ss and Ss ) and 1/4 recessive phenotype with alleles ss.
Ss × Ss
progeny obtained are SS, Ss, Ss and ss.
Thus, the correct answer is option (3).
