Which part of DNA carries the genetic information?
Which part of DNA carries the genetic information?
Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.
How does the amount of DNA produced in a cell during mitosis compare with that produced during meiosis?
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
Are mirror images biology?
Almost all biological molecules exist as two different spatial structures that are related to each other like image and mirror image. These molecules are referred to as enantiomers. Scientists from the German Cancer Research Center (DKFZ) in Heidelberg are working to synthesize biomolecules in their mirror-image form.
What is the meaning of mirror life?
Mirror life (also called mirror-image life) is a hypothetical form of life with mirror-reflected molecular building blocks. Although this alternative life form has not been discovered in nature, efforts to build a mirror-image version of biology’s molecular machinery are already underway.
Do the two strands of DNA carry the same genetic information?
Both strands of double-stranded DNA store the same biological information. This information is replicated when the two strands separate. A large part of DNA (more than 98\% for humans) is non-coding, meaning that these sections do not serve as patterns for protein sequences.
How much DNA is present in each phase of mitosis?
Mitosis ends with 2 identical cells, each with 2N chromosomes and 2X DNA content. All eukaryotic cells replicate via mitosis, except germline cells that undergo meiosis (see below) to produce gametes (eggs and sperm).
