Instructions: 1 Using the DNA sequence, make a complementary RNA strand from both the human and the cow. Write the RNA directly
Ksenya-84 [330]

Answer:

Please find the complete table attached as an image

Explanation:

This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code).

- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc.

- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid.

The table has been completed and attached below. Note that in the amino acids row;

GLY means Glycine

ILE means Isoleucine

VAL means Valine

GLN means Glutamine

CYS means Cysteine

THR means Threonine

SER means Serine

PHE means Phenylalanine

ALA means Alanine

LEU means Leucine

Why might there be more dissolved oxygen in a lake in Vermont than in a similar sized lake in Florida in summer?
givi [52]
In summer, the temperature of Vermont is lower than that in Florida. And the temperature is an important factor influences the gas dissolving ability. When temperature increases, the ability will decrease. So there is more dissolved oxygen in Vermont's lake.

Are Sarcomeres made of amino acids?
nevsk [136]

Answer:

A titin mutation that occurs in muscular dystrophy with myositis (mdm) mice results in a predicted 83 amino acid deletion in the N2A and PEVK regions of the titin protein. Muscles from mdm mice are actively more compliant  possibly owing to the deletion in titin's I-band region. This suggests that modulation of titin stiffness in active sarcomeres by the proposed titin–thin filament interaction may be affected by the mdm mutation. The answer is YES I believe.

Explanation:

I believe the answer is yes from my deep reaserch. You may want to research in your texts book/lesson or courses and review what your teacher/professer has given you.

Regulatory and basal transcription factors regulate transcription by binding to the promoter.A) True B) False
Licemer1 [7]

Answer:

False

Explanation:

In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.

There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.  

Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.
