Answer: The corret DNA sequence is ACUGCUAGCAU.
Explanation: The common mistake that they make is, they forget to replace thymine with uracil as a base pair of Adenine. During DNA transcription Thymine is replaced by Uracil in production of messenger RNA. Uracil is a de-mythylated form of thymine and requires less energy to produce.
Answer:
Proteins.
Explanation:
Ribosomes are complex molecules present in all living cells, they are also called organelles. It serves as the site for protein synthesis. They can be gound freely in the cytoplasm or bound to certain organelles like the endoplasmic reticulum. They consist of two major structural components: the small ribosomal subunits, which read the mRNA, and the large subunits, which join amino acids to form a polypeptide chain.
There are 3 types of Ribosomes which are:
• Ribosomes link amino acids together in the order specified by messenger RNA (mRNA).
• Each unit also consist of ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins.
• Transfer ribosomes (tRNA)
Answer:
Explanation:
Deoxyribonucleic acid is said to contain instruction for species characteristics because it carries the information that characterize an individual.
DNA are made up of Nitrogenous bases that are unique codes specify by an individual and no two person has the same the DNA.
Genes are genetic information or instruction that specify an individual. it is located in the chromosome in the nucleus. DNA contains gene which helps to make molecules called proteins. It is the basis of all inheritance and the expression of the gene is what produces the phenotype that is visible.
The answer is; B
Sometimes winds carry the sand of the beaches causing erosion. The fences act as breakers of this wind erosion. As wind tries to carry the sand, they encounter the fence and 'break'. Therefore, the sand is deposited along the fence forming a sand dune. These dunes also form protection from storm surges.
