Answer:
The Parents may have had heterozygous genotypes.
Explanation:
Normal wings could be the dominant allele that is expressed in the phenotype, and altered wings could be the recessive allele. If both parents had a heterozygous genotype, it is possible for the offspring to have a homzygous recessive genotype.
Answer:
Laminin refers to an extracellular protein, which exhibits the characteristic of binding the cells with each other, that is, possessing adhesive features. Generally, fibronectin is used for adhesion, however, it has also been found that coating of laminin can also be used for adhesion.
Laminin works in adhesion as it possesses three shorter arms that help in sticking other molecules together and assists in the formation of sheets. Laminin can also help in making the properties of adhesion better by combining with the receptors like integrin-binding receptors and the receptors present on the surface of the plasma membrane. Hence, in my opinion, using laminin on the surface of tissue culture dishes can improve the property of adhesion much more.
Well,
DNA stands for deoxyribonucleic acid. RNA stands for ribonucleic acid. Whereas DNA contains deoxyribose, RNA contains ribose. Unlike DNA, which holds together through hydrogen bonds, RNA does not employ hydrogen bonding. DNA has the following nucleotide bases: adenine, cytosine, thymine, and guanine. Three of RNA's nucleotide bases are the same: adenine, cytosine, and guanine. In RNA, thymine is replaced with uracil. Finally, DNA only exists in the nucleus as nuclear DNA or in mitochondria as mitochondrial DNA. RNA travels back and forth from the nucleus to the ribosomes as a part of protein synthesis. There are two types of RNA: Messenger RNA (mRNA) and Transcription RNA (tRNA).<span />
