If Mendel had studied the seven traits using a plant with 12 chromosomes instead of 14, in what way would his interpretation have been different?
He would have mapped the chromosome.
He would have discovered blending of incomplete dominance.
He would not have discovered the law of independent assortment.
He would have discovered sex-linkage.
Extranuclear chromosomes occur in:
peroxisome and ribosome
chloroplast and mitochondria
mitochondria and ribosome
chloroplast and lysosome
Gene and cistron words are sometimes used synonymously because:
one cistron contains many genes
one gene contains many cistrons
one gene contains one cistron
one gene contains no cistron
'Signal hypothesis' for the biosynthesis of secretory type of proteins was proposed by:
Camillo Golgi
Blobel and Sabatini
Baltimore
Sheeler and Bianchi
Genetic code consists of
Adenine and guanine
Cytosine and uracil
Cytosine and guanine
All of the above
DNA elements, which can switch their position, are called
exons
introns
cistrons
transposons
A fruit fly heterozygous for sex-linked genes, is mated with normal female fruit fly. Male specific chromosome will enter egg cell in the proportion
1 : 1
2 : 1
3 : 1
7 : 1
In humans, there are two type of sex chromosome, called X and Y chromosomes. A person with two X chromosomes is called:
Female
Male
Autosomes
All of these
