A) Crossing over is the mechanism of genetic variation that results from the exchange of gene segments between non-sister chomatids.
Answer: they have to maintain homeostasis, so they remove waste to do so..
Answer:
Explanation:
1. Complex carbohydrates (AKA polysaccharides like starch)- monosaccharides linked together by glycosidic linkages
Fats (AKA triglycerides) - Fatty acids
Proteins- Amino acids.
2. Name the 3 portions of the small intestine in order - The Duodenum, Jejunum, and Ileum.
3. In which of these 3 portions does the greatest amount of nutrients absorption occur - Jejunum
The restriction endonuclease EcoRI cleaves the DNA sequence 5'-GAATTC-3' in such a way as to leave a 5' overhang, which is often referred to as a "sticky end". To 5' overhang with the complementary sequence this sticky end adhere.
- The palindrome EcoRI restriction site breaks DNA after G and creates sticky ends with AATT. G/corresponding AATTC's DNA sequence is CTTAA/G, where "/" designates the location of the peptide bond break.
- When the ssDNA sequence 5'-GAATTC'-3 is recognised by the restriction endonuclease EcoRI, a single-strand cut is made between the G and A nucleotides.
- At the ultimate end of double-stranded DNA, an overhang is single-stranded DNA. This can occur on either strand, and if it does, there will either be a 5' overhang on the 5' end of the strand or a 3' overhang on the 3' end of the strand.
