Answer:Non-Polar and Neutral, Polar and Neutral, Polar and Acidic, Polar and Basic
Explanation:
The name of the group that consists only of modern humans and their direct ancestors is known as Hominidae. It is also called by the name of Hominids or great apes. Originally the term Hominidae referred to only the humans and their closest relatives. There are still people that continue to use this term in its restricted sense, rather than the modern sense.<span />
A skin cell in G2 of interphase has twice as much DNA as it had in G1.
A skin cell is somatic cell that undergoes mitosis (cell division). Mitosis together with interphase is part of the cell cycle.
Interphase also known as a phase for the preparation for division consists of three phases:
• G1- cell becomes larger, copies organelles, and makes the building blocks necessary for the new cell
• S-cell copies its DNA in the nucleus (that is why G2 phase has twice as much DNA as it had in G1)
• G2 – cell continues to grow, makes proteins and organelles.
During the mitosis, the cell separates its DNA into two and divides its cytoplasm, forming two new daughter cells.
Peristalsis is the process of contractions that move food through the intestines.
Answer:
The correct answer would be 5' capping, 3' polyadenylation , and intron splicing.
In eukaryotes, transcription results in the formation of pre-mRNA which needs to be processed in order to become mRNA (messenger ribonucleotide).
The pre-mRNA processing include:
- Addition of 5'cap (usually modified guanine nucleotide) at the 5'-end of the RNA. It prevents the RNA degradation and also help in the attachment of ribosome for translation.
- Addition poly-adenine (poly-A) tail at the 3'-end of the RNA. It increases the stability of the RNA and helps in its export out of the nucleus.
- Lastly, splicing takes place which removes the introns and joins the exons. Alternative splicing can also take place in order to produce many mRNA from a single gene.
