Answer:
B
Explanation:
soil being depleted to nitrogen due to high runoff
TRNA reads codons from mRNA and then brings attached amino acids accordingly. Amino acids are connected in long chains called proteins.
Answer:
B. Base pairing occurs within an RNA molecule to give RNA the three-dimensional shape needed for specific functions.
Explanation:
Ribonucleic acid, known as RNA, is a type of nucleic acid found in living systems. In opposition to the other type of nucleic acid (DNA), RNA is a short single stranded molecule. Both DNA and RNA are made of nucleotides, composed of a phosphate group, nitrogenous bases and a pentose sugar.
The presence of ribose sugar and Uracil base in RNA instead of deoxyribose sugar and thymine base respectively structurally differentiates the molecule from DNA. However, base pairing occurs within the RNA molecule to form the three-dimensional shape of the RNA, which is key to the specificity of its function.
A point defined with reference to another position, either fixed or moving; the coordinates of such a point are usually bearing, true or relative, and distance from an identified reference point.
Answer: DNA polymerase I is able to proofread; DNA polymerase III is not.
Explanation:
Escherichia coli is a gram negative anaerobic bacteria that is found in the gastrointestinal tract of and humans and animals. Escherichia coli has 5 types of DNA polymerase.
a. Polymerase I is used to repair any damaged DNA and proof reading
b. Polymerase II is used in proof reading, DNA Replication and repairs.
c. Polymerase III is primarily responsible for DNA replication. It also has the ability to proof read.
d. Polymerase IV is used to change genetic information of Escherichia coli.
e. Polymerase V is used in DNA repair in Escherchia coli.
