Answer:
2) DNA Makes Up Our Body Structure Like Muscle
Explanation:
There Are Pairs In Our DNA That Determine Certain Physical Features Or Traits. ( These Are Called Gene's ) The Genes That You Have In Your Body Right Now, Makes Up Your Genotype. This Genotype Then Determines Your Physical Appearance, Which Is Called Your Phenotype!
The study of comparative anatomy predates the modern study of evolution. Early evolutionary scientists like Buffon and Lamarck<span> used comparative anatomy to determine relationships between species. Organisms with similar structures, they argued, must have acquired these traits from a common ancestor. Today, comparative anatomy can serve as the first line of reasoning in determining the relatedness of species. However, there are many hidden dangers that make it necessary to support evidence from comparative anatomy with evidence from other fields of study.</span>
The word “hydro” means water and “phobic” means away or repel. So, the correct answer would be B, Repels Water
Answer:
DNA ligase
Explanation:
DNA replication is a process whereby a particular DNA makes a copy of or synthesizes itself. It consists of several steps with some important enzymes for successful, error free replication. The various steps are as follows;
- Unwinding of the double helix structure of the DNA and formation of replication fork. The enzyme involved here is the DNA helicase.
- Primer, a short piece of RNA becomes synthesized and binds to the 3' end of one of the 2 strands of the DNA, the leading strand. The enzyme involved is the DNA primase.
- Replication of the <em>leading strand</em> then proceeds with the elongation of the primer through the addition of bases in the 5' to 3' direction leading to the formation of continuous strands.
- The other strand of the DNA, known as the <em>lagging strand </em>starts its own replication by binding with multiple primers at different regions of the strand. Bases are then added to each primer leading to the formation of several, short discontinuous DNA strands known as Okazaki fragments. The enzyme involved in the elongation process is the DNA polymerase.
- Next is the termination of the replication process after the formation of the continuous and discontinuous strands. Exonuclease enzyme removes primers from the synthesized strands. Primers are replaced by appropriate DNA bases and the Okazaki fragments are joined to form a unified DNA strand by an enzyme known as the DNA ligase.
The many, few nucleotides long DNA segments observed by the Biochemist are the Okazaki fragments that should have been joined together by the DNA ligase.
Hence, DNA ligase must have been the component left of the mixture.
