Maternal inheritance of coiling of shell in snail (limnaea peregra) is well established. The dextral coiling depends on dominant allele D and sinistral coiling depends upon recessive allele d. A female F1 progeny of dextral(Dd) type is crossed with a male dextral (Dd). What will be the phenotype ratio in progeny?

The xanthophyll cycle, which comprises the three carotenoids violaxanthin, antheraxanthin, and zeaxanthin, establishes an ability to dissipate excess light energy in the leaf, Under high light the conversion of the carotenoids such as

Following statements are being
made regarding gradients of specific translational inhibitors in drosophila.
A. In
the anterior region, Bicoid protein prevents translation of the caudal message
by binds to a specific region of caudal’s 3′UTR. Here, bicoid recruits Bin3 (a
translation inhibitor) which prevents translation of caudal in the anterior of
the embryo.
B. In
the posterior region, Nanos protein prevents translation of the hunchback message
by forming a complex with several other ubiquitous proteins, including Pumilio
and Brat. This complex binds to the 3’UTR of the hunchback message, where it
recruits d4EHP and prevents the hunchback message from attaching to ribosomes.
C. In
the anterior region, Bicoid protein prevents translation of the caudal message
by binds to a specific region of caudal’s 5′UTR. Here, bicoid recruits pumilio
and brat (a translation inhibitor) which prevents translation of caudal in the
anterior of the embryo.
D. In
the posterior region, Nanos protein prevents translation of the hunchback message
by forming a complex with several other ubiquitous proteins, including bin3 and
smaug. This complex binds to the 3’UTR of the hunchback message, where it
recruits d4EHP and prevents the hunchback message from attaching to ribosomes.
