Answer:
In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.
In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation. This means that transcription and translation are physically separated. The primary transcript, heterogeneous nuclear RNA (hnRNA), undergoes extensive post-transcriptional processing to make a messenger RNA (mRNA)molecule that can pass through the nuclear membrane.
Explanation:
Answer:
<em>Low temperature slows down the movement of molecules and slows the speed of the reaction</em>
Explanation:
At low temperatures, the number of successful collisions between the enzyme and substrate is reduced because their molecular movement decreases. The reaction is slow.
The bones that make up our arms are pretty similar to those of a turkey's wings. ... We can tell tibiae are homologous in humans, monkeys, tortoises, and turkeys because they always connect with the upper leg bone (femur) and the bones of the foot, and similar muscles connect them to other bones.
The brain can only use glucose and ketones for energy, so e.) a and c
Answer:
Our lack of body hair and our variable skin color are some of the traits that set us apart from our closest primate relatives. Wavelengths of light are reflected or absorbed by pigment in the skin called melanin. Melanin is synthesized in structures called melanosomes that are produced by cells called melanocytes.
