Is Helicase functional in elongation?

Biology
1 answer:
Wittaler [7]3 years ago
6 0

Answer:

Proteins with seven conserved "helicase domains" play essential roles in all aspects of nucleic acid metabolism. ...

Explanation:

Known or putative helicases are required for general transcription initiation and for transcription-coupled DNA repair, and may play important roles in elongation, termination, and transcript stability.

Halobacterium has a photosynthetic membrane that appears purple. its photosynthetic action spectrum is the inverse of the action
a_sh-v [17]

Yellow- Green Wavelength of light at peak absorption of 565nm.

Halobacterium is known to be a member of Archaea and they thrive in very salty environment such as Great Salt lake and Dead Sea. Halobacteria under the process of photosynthesis with chlorophyll and they make their ATP from the sunlight using bacteriorhodopsin and halorhodopsin as photosynthetic pigments.

However, photosensory pigements found in Halabacterium were:

1. photosystem 565 which is used to respond to yellow –green light in other for cell to find optimum conditions for ATP synthesis and photophosphorylation and they have peak absorbtion at 565nm.

2. Photosystem 370 nm appears to be responsible for the protective avoidance of blue/UV light.

jekas [21]

Answer:

the correct answers are as follows

12:

b. Testcross- an organism with dominant phenotype but unknown genotype is crossed with homozygous recessive organism for the same trait. Based on the results obtained, if all offsprings have the same phenotype, then the parent is homozygous, but when a 1:1 ratio is observed in the offsprings, then the parent is heterozygous.

13.

e. Watson and Crick- they both used the crystallographic images from Franklin, analyzed them to first elucidate the 3D structure of the DNA and propose it to the world.

14.

c. Intracellular and commonly found in the cytoplasm- the receptors of steroid hormones are generally present within the target cell either in the cytoplasm or nucleus, since they alter gene expression.

15

e. Certain prokaryotes/bacteria- this is a process that will enable disease-causing pathogens to communicate and cooperate with their group, by the release of autoinducers that increase their cell density.

jeyben [28]

Question:All known organisms use genetic information to produce protein molecules via the same genetic code. This finding strongly supports the hypothesis that __________.

a) the earliest macromolecules probably arose when lightning struck an oxygen-free atmosphere

b) all organisms are descended from one or a few common ancestors

c) the genetic code readily evolves by natural selection

d) there's only one possible way to encode information in a macromolecule

Answer:

b) all organisms are descended from one or a few common ancestors

Explanation:

Protein synthesis occurs when the nucleotide sequence of the mRNA is read in the form of genetic codes. A specific genetic code specifies the same amino acid in all living beings. For example, the code "UUU" codes for phenylalanine in all the living beings irrespective of their species. This suggests that all the life forms have originated from one or few common ancestors and the genetic code has been preserved during the course of evolution of various species.
