In tertiary structure of $DNA$, what is a histone octamer?

A complex consisting of eight positively charged histone proteins (two of each $H2A, H2B, H3 and H4$) that aid in the packaging of $DNA.$

Lampbrush chromosomes are found inside

Barbara McClintock is famous for her work on

When the genomes of two people are cut using the same restriction enzyme, the length and number of fragments obtained are different, this is called

A pure breeding pea plant with the dominant phenotype of character $A$ and recessive phenotype of character $B$ was crossed with another pure breeding plant with the recessive phenotype of $A$ and dominant phenotype of character $B. A$ offspring of this cross was crossed with a homozygous recessive for both the characters -$A$ and $B$. The following results are obtained $22$ were phenotypically dominant for $A$ and recessive for $B$.

$4$ were phenotypically dominant for both $A$ and $B$.

$4$ were phenotypically recessive for both $A$ and $B$.

$24$ were phenotypically recessive for $A$ and dominant for $B$.

These results show that
