real stems, leaves or roots and are also known as nonvascular plants. Plants
with true roots are known as vascular plants. Vascular plants have real roots, stems and leaves and contain vascular tissues.
The stars that is very dim and red is called Red Dwarfs.
Answer:
nucleotides are only building blocks whose combinations determine different codons which subsequently associate in a sequential manner in order to create different amino acid combinations
Explanation:
A gene is a specific segment of DNA whose (nucleotide) sequence is copied into an RNA during the process of transcription, typically a messenger RNA (mRNA) molecule which is subsequently used to synthesize a protein. During translation, each triplet of nucleotides, i.e., each codon, corresponds to a specific amino acid. There are 64 possible codons (4³: 64), which can combine in different ways to create different amino acid combinations, and thus they are responsible for the generation of a huge amount of proteins coded by a given genome.
The answer is; Choice D
ABC transporters are transmembrane proteins that enable active transportation of substances across the cell membrane. The protein is important in the movement of substances against their concentration gradient using ATP energy. ATP binding causes it to change conformation and bind the molecule being transported.
