Yes it is AB because a blood test or either AB or type O is more informative
Answer:
The similarities and differences between DNA and RNA are given as follows:
Explanation:
Similarities:
Both are made up of nucleotides
Nucleotides are made up of nitrogenous bases, a pentose sugar, and the phosphate backbone.
Both DNA and RNA have four nitrogenous bases each - two purines two pyrimidines
Purine binds with pyrimidines
Differences
DNA uses the nitrogenous bases adenine, cytosine, thymine, and guanine whereas RNA uses adenine, cytosine, uracil, and guanine. Uracil lacks a methyl group on its ring
RNA contains the sugar ribose that has an extra -OH while DNA contains the deoxyribose sugar that has H at the 2 carbon.
DNA is double-stranded while RNA is a single-stranded
Under alkaline conditions, DNA is stable while RNA is not stable.
Natural common disorder function seeds
The answer would be C) Energy flows through an ecosystem and cannot be recycled.
The correct ones are:
- Differential gene expression affects the developmental process in animals.
- Positional information controls pattern formation.
- Homeotic genes code for transcription factors that control the development of segment-specific body parts.
- Cells receive molecular signals that communicate their position in relation to other cells.
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product, allowing it to produce end products such as protein or non-coding RNA and, as a result, affect a phenotype.
A homeotic gene is any of a group of genes that control the pattern of body formation in organisms during early embryonic development. These genes encode proteins known as transcription factors, which direct the formation of various body parts.
Molecular signaling refers to molecules that transmit information between cells in the body. However, the molecular properties of signaling molecules can vary greatly.
