Focuses on the uniqueness of the turtle among vertebrates. Consideration of the special features of the turtle's shell; Extinct creatures believed to be turtle ancestors; Evolutionary changes undergone by turtles; Division of the turtles into two lineages; How two different pulley mechanisms categorize...
Mitochondrial DNA maintenance in vertebrates. The functional state of mtDNA requires a great number of factors for gene expression, DNA replication, and DNA repair. These processes are ultimately ... GS Shadel,DA Clayton - 《Annual Review of Biochemistry》 被引量: 2049发表: 1997年 Human ...
2a). Moreover, the intermediately sized repertoire of bed bug chemoreceptors is in line with the moderate complexity of its chemical ecology, being an obligate blood feeder such as tsetse flies (Glossina morsitans)28,29, but having a broader host range that encompasses many vertebrates, whereas...
We identify unique features of mtIF2 that are required for specific recognition of fMet–tRNAMet and regulation of its GTPase activity. Finally, we observe that the ribosomal tunnel in the initiating ribosome is blocked by insertion of the N-terminal portion of mitochondrial protein mL45, which ...
Describe the fibrous skeleton of the heart, and explain its functions. What makes the compact and spongy bone so different besides the appearance? Describe the anatomical features that will help you determine that a species is bipedal. What characteristics do all ver...
For example, in vertebrates, the Sex-determining region Y (SRY) functions as a determinant of male differentiation in mammals [2]. In rainbow trout, the sex-determining region Y (SdY) [3], which is homologous to the immune system gene interferon regulatory factor 9 (IRF9), triggers ...
What are the main orders of placental mammals? What are some representative species and distinguishing features of each of those orders? List five characteristics that make vertebrates and invertebrates different. Mammals and birds eat more often than reptiles. Which of the following traits shared by...
The exogenous epsilonretroviruses of fish include walleye dermal sarcoma virus and the walleye epidermal hyperplasia viruses (WDSV, WEHV; genus Epsilonretrovirus). These viruses encode a distinct Env lacking the hallmark features of a gamma-type Env, and gammaretrovirus-related ERV are largely absent...
Sequence comparison of human TRIM family proteins The TRIM proteins appeared with the metazoans, and increased in number along with the evolution of vertebrates (Reymond et al., 2001). TRIM proteins are found in the nucleus as well as the cytoplasm. Many cytoplasmic TRIM proteins have a carboxy...
CDK1–cyclin B phosphorylates a large number of substrates17 and, in vertebrates, a number of phosphatases have been shown to counteract its activity16,18. Ultimately, however, CDK1 activity is depleted by the beginning of anaphase as a result of cyclin A and cyclin B ubiquitination and ...
