Answer:
Most biological laundry detergents contain lipase and protease enzymes, both of which are found in the body. Lipases break down fats and oils, while proteases work to break down protein chains. Their ability to break down these compounds makes them excellent for stain removal.
Explanation:
A genetic trait that helps an organism be more successful in its environment
Answer:
C
Explanation:
This is a monohybrid cross between involving a gene coding for earlobe. The allele for free earlobe (F) is dominant over that of attached earlobe (f).
N.B: let F represent the gene involved.
A genotypic ratio is the ratio derived from the offsprings based on the actual genetic make-up and not based on their phenotypic appearance as in phenotypic ratio.
A homozygous individual is an individual having the same kind of alleles for a gene while a heterozygous individual is one that has two different alleles i.e. combination of the dominant and recessive allele.
The monohybrid cross is between an individual with attached earlobe (ff) i.e. homozygous recessive individual. (Note that, a recessive trait will only be expressed in a homozygous state) and a heterozygous free earlobeb individual (Ff). (See attached picture). Ff × ff
The resulting four offsprings will
be expected to have only two distinct genotypes i.e heterozygous (Ff) and homozygous recessive (ff) in an equal ratio i.e. 2:2 ~ 1:1
Answer:
The correct answer is d. eukaryotes almost always produce polycistronic mRNA
Explanation:
In eukaryotes one transcription unit contains the information of only one gene which codes for only one protein or polypeptide therefore eukaryotic mRNA is called monocistronic mRNA.
In prokaryotes transription unit contains set of genes adjacent to each other which are transcribed together and codes for multiple proteins. So prokaryotic mRNA is called polycistronic mRNA.
Almost all messenger RNA present in eukaryotes are monocistronic mRNA because eukaryotes are more complex than prokaryotes and require modification at many stages which is easily possible with monocistronic mRNA.
