Answer: c) amino acid
Explanation: A codon is an mRNA sequence which contains three nucleotides that codes for a particular amino acid. The codons on the mRNA are read by the ribosome during translation and the amino acid coded for by each codon is used to make a protein. There are 64 different codons in existence, each amino acid is coded for by at least one codon. Some amino acids have more than one codon. For example, the amino acid Leucine is coded for by six codons: UUA, UUG, CUU, CUC, CUA and CUG while the amino acid phenylalanine is coded for by two codons: UUU and UUC.
The nucleus is the part of the cell, or organelle, that contains the genetic material and controls the cell's movement. It consists of the genetic material, the nucleoleus, and the nuclear membrane.
Nucleus- the nucleus controls all of the cells activities, including how the cell grows,develops,and divides.
Answer: The common ancestor of humans and chimpanzees had 24 pairs of chromosomes, and at some point in the human lineage, two chromosomes fused end to end, providing some selective advantage.
Explanation: Humans evolved in a different way due to external factors and at some point in the human lineage, two chromosomes blended giving humans a selective lead.
