What are the functions of the promoter sequence and the terminator sequence in DNA?

Biology
1 answer:
Veseljchak [2.6K]3 years ago
6 0

Answer:

A

Explanation:

Promoter region on DNA is the point on DNA where polymerase enzyme attaches so it can begin the translation of genes/operon downstream. Terminator region on the DNA is the point that causes the polymerase to terminate transcription. For example, the terminator regions may cause the transcribed nascent mRNA to form a hairpin structure at the terminator sequence hence causing  the polymerase enzyme to detaches from the DNA strand.

Evgen [1.6K]

Answer:

A. The DNA-bending function of TBP cannot be performed by another protein in the general transcription factor complex.

Explanation:

TATA  box sequence binding protein binds to aspecific region on DNA known as TATA Sequence. TATA binding protein binding to the DNA Sequence is necessary because it generates <em>bending of DNA till 80° angle.</em>

<em></em>

BINDING of all transcription factors depends solely upon the binding of TBP directly, that is why TATA binding proteins bonding to DNA is very important for initiation of transcription. Any other protein does not have the capacity of band formation with DNA. Hence, A. the DNA-bending function of TBP cannot be performed by another protein in the general transcription factor complex.

What is one of the reasons why Gregor Mendel chose to study
Tcecarenko [31]
Gregor Mendel was the father of the field of genetics, which seeks to explain how traits are passed on from one generation to the next.
To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits.

Birds and humans are theorized to have a common ancestor because they have homologous structures. Which evidence best supports t
Bogdan [553]

Answer:

They each have vestigial structures.

Explanation:

Birds and humans have a common ancestor as they have homologous structures.

Vestigial structures are the organs that have some important functions in the past but now in present, they do not perform any function.

Both humans and birds have vestigial structures such as humans have an appendix and ear pinna and wings of flightless birds such as ostrich.

Hence, the correct answer is "They each have vestigial structures.".
