The Cell, the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa, others, such as nerve, liver, and muscle cells, are specialized components of multicellular organisms. In another words, without cells we wouldn't be able to live or function correctly.
The overall concept a clad organ aims to prove is evolutionary relationships among each organism.
Answer:
The biological level of organization represented by all of the three steps of gene expression products is <em>the central dogma of molecular biology.</em>
Explanation:
DNA is divided up into functional units called genes. Each of them provides instructions for a functional product, that is, a molecule nedeed to perform a job in the cell. In many cases, the functional product of a gene is a protein.
The functional products of most known genes are polypeptides. Genes that specify polypeptides are called protein-coding genes.
Not all genes specify polypeptides. Instead, some provide instructions to build functional RNA molecules, such as transfer RNAs and ribosomal RNAs that play roles in translation.
The construction of polypeptide involves two major steps: transcription and translation. During the transcription, the DNA sequence of gene is copied to make an RNA molecule and in translation the sequence of mRNA is decoded to specify the amino acid sequence of the polypeptide.
Answer:
When we say that a trait has been "selected for", this means that. individuals with that trait reproduce more than individuals without that trait.Explanation:
Answer:
Common mistakes and misconceptions. Anaerobic respiration is a normal part of cellular respiration. Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. However, if oxygen is not present, some organisms can undergo fermentation to continually produce ATP.
