DNA helicase and DNA polymerase are alike in that both are...?

Biology
1 answer:
just olya [345]2 years ago
5 0

Answer:

Both DNA helicase and polymerase are enzymes capable of binding double stranded DNA able to break the hydrogen bonds between the nucleotides. Helicase case splits  the doubled stranded helix apart so that the polymerize can start and produce the copies Hopefully this Helps!

Investigator Benton uses several methods to analyze hair samples found at the crime scene. He examines the physical features of
Diano4ka-milaya [45]

Answer:

Medulla.

By analyzing the DNA extracted from the hair follicle, the medullary index and the pattern of medulla in the hair samples obtained from a crime scene, an investigator can identify the owner.

Explanation:

The hair consists of follicle and shaft. The follicle is the part of the skin, where the hair grows and the hair shaft has three layers: an inner medulla,  a cortex, and an outer cuticle.

The morphology (physical characteristics) of hair provides a broad detail on the racial background of  an individual and an investigator can identify a  group of people who share similar  traits. But the hair without follicle cells attached to it, cannot  be used to identify a specific individual. If the follicle of a hair is present, then it can lead to individual identification by DNA analysis. Also the medulla of animals is larger than that in the humans. By comparing the medullary index (the ratio of the diameter of the medulla to the diameter of the entire  hair), it can be determined if the hair obtained from crime scene belongs to animals or humans. The macroscopic (length, color, and curliness) and  microscopic characteristics ( pattern of the medulla, pigmentation of  the cortex, and types of scales on the cuticle) of the hair samples are studied during a crime investigation. If the entire hair follicle (follicular tag) is present in the hair samples found at the crime scene, the blood and tissue attached to  the follicle is extracted and analyzed using DNA profiling. DNA analysis of the hair follicle provides  an identification with greater accuracy than the hair shaft.

What evidence suggests that RNA appeared before DNA? ribozymes, catalytic RNA, play pivotal roles in modern cells ribosomes are
mote1985 [20]

Answer:

<em>The evidence that suggests  RNA  appeared before DNA is the fact that RNA can act as an enzyme to self-edit their own genetic code. </em>Moreover, it has the ability to store genetic information, while transfer and ribosomal RNA have the ability to translate genetic information into proteins.

Explanation:

RNA has a great capability as a genetic molecule, it once had to carry on hereditary process on its own. It is absolutely sure that RNA was the first molecule of heredity. However, a single stranded RNA is rather unstable and easily damaged by enzymes. By essentially multiplying the existing RNA molecule, and using deoxyribose sugar instead of ribose.

<em>The DNA evolved as a much more stable form to pass genetic information with accuracy.  It shows a biological evolutionary purpose .</em>
