Answer & Explanation:
After a complimentary DNA chain is generated as messenger RNA (mRNA), Sequence of nuclotides in a mRNA directs the addition of a specific sequence of amino acids to form the protein. This usually occur on ribosome.
The polypeptide chain now increases in length by covalent attachment of successive amino acids units, each carried to the ribosome and correctly positioned by its transfer RNA (tRNA). The completion of the polypeptide chain is signalled by a termination codon present in the mRNA.
Answer: While Biology is the study of living things, living things themselves are made up of chemical composition. That being said, our survival is dependent on the reactions taking place inside and outside the body. Hence, to understand living things, biologists needs a good understanding of chemistry.
Answer:
One relative of whales was Pakicetus, which lived 50 million years ago. (the group of marine animals that includes dolphins and whales).

Aneuploidy is a condition in which the chromosomes do not separate<span> properly between daughter cells </span>
The similarity just lies in the structure. DNA is double-stranded, however it is twisted/helical, while the ladder does not twist. However, other than that, they are quite similar. The 2 strands (5' -> 3' and 3' -> 5') of DNA serve as the 2 vertical sides of the ladder. The base pairs of DNA are what connect the two strands together. So, in terms of the ladder, think of the steps of the ladder as the base pairs. Think each step as consisting of 2 entities joining together to make 1 big step. For example, think of a step having 2 halves down the middle. 1 half would be a guanine (base) and the other half would be a cytosine (base). Guanine is connected to the 5' --> 3' strand (Left vertical side of ladder) while the Cytosine is connected to the 3' --> 5' strand (right vertical side of ladder). These two come together at one of their ends and base pair, which appears to look like the steps on a ladder.
