Ribonucleic acid, the basic unit of RNA, has a hydroxyl (-OH) on the second carbon atom. On the other hand, the deoxyribonucleic acid, the basic unit of DNA, has a single hydrogen in the second carbon. This chemical structure difference makes RNA heavier than DNA due to the extra carbon atom.
The RNA/RNA-DNA hybrids can be separated from double-standard DNA using a high-resolution centrifuge due to this difference in weight. The image belows shows the extra oxygen atom in the 2' carbon
Answer:
Answer is option A (true).
The child has brown eyes.
Explanation:
In this example, B represents the allele for brown eyes which is dominant and b represents the allele for blue eyes which is recessive. The color of the eyes, brown and blue are the two phenotypes (physical appearance) obtained from the combination of these two alleles. Since B is the dominant allele (brown eyes), both the genotypes BB and Bb will produce brown eyes. The genotype (genetic code from the combination of alleles inherited from parents) of the child is Bb, so she has brown eyes. The offspring will get blue eyes, only if the genotype is bb (homozygous recessive).
